Best Super King Mattress 2026: 10 Ranked, One Claims 2,000 Springs

By · Updated

Two hybrid listings in this set contradict themselves on weight. One super king mattress, 180x200x30 cm, declares an item weight of 17 g; a second, 25 cm deep, declares 454 g. Every other hybrid here sits between 17 kg and 45.2 kg. Meanwhile the most expensive model, at £829, lists 600 pocket springs — fewer than the 868 of the £143.64 model and under a third of the 2,000 that a £220.99 listing claims. Layer counts do not hold up either: 12 layers inside 22 cm is 1.8 cm per layer.

We ranked ten of the best super king mattress options on Amazon on the numbers the sellers publish, how those numbers compare with each other, price against spring count, and the full review histogram rather than the star average alone.

“I recently purchased this mattress, which has exceeded my expectations for comfort and support. After doing some research, I decided on a single mattress measuring 90cm x 190cm x 25cm, and I couldn't be happier with my choice.The mattress arrived vacuum-packed in a protective plastic bag, neatly boxed for easy handling. Since I was about to go on holiday, I took the precaution of laying the mattress out flat as soon as it arrived. After carefully removing the plastic covering, I allowed it to expand to its original shape for several days while I was away. I was pleased to notice minimal odour during this process, and any residual smell dissipated shortly after unboxing.Once I returned from my trip, I placed the mattress on my new bed frame. The first night was truly a revelation; the mattress was incredibly comfortable, offering an excellent balance of support and pressure relief. I found myself sinking into the surface just the right amount without losing that essential firmness. It is classified as medium-firm, and although it's a touch softer than I initially anticipated, this slight give adds to overall comfort and makes for an inviting sleeping experience.I was delighted to wake up after my first night feeling well-rested and refreshed. The support provided by the mattress alleviated pressure points, resulting in deep, restorative sleep. Having experienced various mattresses in the past, I can honestly say this one stands out in its value and quality.Overall, I am thoroughly satisfied with my purchase. The combination of affordability, comfort, and support makes this mattress a great investment for anyone seeking a restful night's sleep. I'm truly enjoying it and look forward to many more nights of comfortable rest ahead.”

“Needed to replace a 10 year old mattress which cost almost a £1000 , ordered a smaller one for my mum previously and was so impressed with the comfort for such a bargain price that I ordered a king size one for myself,it came vacuum packed so easy to transport upstairs and within minutes of opening became a fully plumped up bed . Can't believe how comfortable it is ,like sleeping on a marshmallow!”

This one takes the top spot on 3,524 ratings at 4.4 stars, and its 900-coil count is the highest credible figure in the top three — the £259.99 dosleeps beside it publishes no coil count at all. The 28.5 kg item weight is the check that matters: it sits in the same band as every other genuine hybrid here, which is exactly why the 17 g and 454 g listings stand out. Each super king mattress in this ranking was judged on whether its own numbers held together. This one's do.

The build is a 9-zone pocket spring unit under gel and wave memory foam, each coil wrapped individually so movement does not travel across. The cover is a Tencel lyocell blend, which the listing says absorbs moisture more efficiently than standard fabric. It is 25 cm deep, medium firm, and the spec table lists box spring, slatted base and solid foundation as compatible. A 100-night trial is included.

Do not buy it if you want a plush feel — medium firm is the only firmness offered, and a plush all-foam option appears further down this list at £199.99. Worth noting that 9 of the 100 histogram entries sit at one or two stars, so the 4.4 average hides a small but real unhappy group. The cover should go on a gentle cycle only, and 7 layers across 25 cm works out at roughly 3.6 cm each.

TeQsli 10 Inch Hybrid Pocket Sprung Mattress, 180x200

TeQsli 10 inch super king hybrid mattress in a box, 25 cm deep
£143.64 4.5 1,412 reviews

The cheapest here at £143.64, declaring 868 pocket springs — 268 more than the £829 model.

Pros

  • £143.64 for 868 individually pocketed springs
  • 38 kg item weight supports the pocket sprung claim
  • OEKO-TEX 100 fabric and CertiPUR-US foam certification stated
  • Handles on both sides, rare at this price
  • 7-zone support with cooling and wave memory foam

Cons

  • No trial period stated anywhere in the listing
  • Marked as neither foldable nor portable
  • 8 layers across 25 cm averages about 3.1 cm each
  • 5 of 100 histogram entries sit at one star

“I bought this mattress for my daughter after moving house and, so far, I'm really happy with it. I was specifically looking for a single mattress and chose the 10-inch TeQsli one, which turned out to be a good choice. The size is exactly as expected and fits the standard single bed perfectly. The firmness is just right—not too hard and not too soft—and it's very comfortable. I was actually quite impressed with the upper layer and even thought it would be nice to use for myself! The mattress arrived compressed and rolled up in a box. It weighs around 20 kg, so it's manageable to get into the room before opening. I followed the instructions and left it for more than three days to fully expand before using it. One thing worth mentioning is that during those first 72 hours, I wouldn't recommend putting a bedsheet or anything else over it, so it has enough space to expand properly. Overall, I'm pleased with the quality and comfort. The price is reasonable too, and I think it's good value for money. My daughter is happy with it, which is the main thing!”

“I normally wouldn't order a mattress online but my husband and I were desperate and on a budget and our daughter needed a new one too.I ordered them during Amazon days so got them for £89 each.I am so glad I went with this brand of mattress.It arrived rolled up and air tight. It say may take hours for it to get into it's fullness. Ours went straight into it.We've had it a few months and we don't wake up with back aches. It gives just enough while still gives support. It's really think but our sheets fit perfectly. Careful sitting on the side when getting up if you're not to graceful as it launches you a bit but it's really sturdy.I highly recommend, especially since it's cost effective and you don't spend hundreds of your money elsewhere.”

Check Price on Amazon More about the TeQsli 10 Inch Hybrid Pocket Sprung Mattress, 180x200

At £143.64 this is the cheapest mattress in the ranking, and it declares 868 individually pocketed springs. The £829 model further down declares 600. In practice that means the cheapest listing here publishes 45% more springs than the most expensive one. The 38 kg item weight is the second-heaviest in the set, and it is consistent with a steel spring unit of that size.

It is a 7-zone super king hybrid mattress: cooling memory foam over a wave memory foam layer, over the pocket spring base. The fabric carries OEKO-TEX 100 certification and the foam is CertiPUR-US certified, both stated in the bullets. Handles on both sides are unusual at this price. It arrives compressed and roll-packed, so it is a super king mattress in a box in the literal sense — the seller asks for time to let it recover its depth.

The catch is maintenance and firmness. The seller asks you to rotate it every two weeks for the first three months, then every other month up to twelve. It is medium firm only. The listing marks it as neither foldable nor portable, and it quotes no trial period anywhere in the spec table.

dosleeps 10.6 inch super king mattress with nine-zone pocket springs, 27 cm
£259.99 4.4 2,686 reviews

Second dosleeps in the top three, and its own fields disagree on depth: 27 cm in three places, 28 cm in a fourth.

Pros

  • 9-zone pocket spring unit with gel memory foam
  • 28.6 kg weight keeps it inside the normal hybrid range
  • CertiPUR-US and OEKO-TEX certification listed
  • 100-night trial stated
  • 27 cm profile, deeper than the 22 cm and 25 cm options

Cons

  • Item Depth says 28 cm while thickness and dimensions say 27 cm
  • 12 layers across 27 cm averages about 2.25 cm each
  • No coil count published in the spec table
  • Bullets are near-identical to the other dosleeps listing here

“This arrived at 8:12pm, I unboxed it, put it on the bed, cut the plastic and watched it expand, it took less than 10 minutes. I am now laying on it writing this and I feel like I'm floating on a cloud! What an amazing bargain, I am so comfortable after years of sleeping on a sprung mattress that had springs broken everywhere. I am looking forward to a really good nights sleep and I think I will finally get one! I cannot believe I bought this mattress for only £140! An absolute bargain!!!”

Check Price on Amazon More about the dosleeps 10.6 Inch 9-Zone Super King Mattress, 27 cm

This is the second dosleeps listing in the top three, at £259.99 and 2,686 ratings. Its spec table carries 12 layers — the highest count in this ranking. However, 12 layers inside 27 cm gives an average of 2.25 cm per layer, the same arithmetic problem as the 22 cm model that also claims 12 layers at 1.8 cm each.

Underneath the layering is a 9-zone pocket spring unit with gel memory foam. It is 27 cm deep, medium firm, and 28.6 kg — again inside the normal band. The benefits field lists both CertiPUR-US and OEKO-TEX certification. A 100-night trial applies, and base compatibility matches the top-ranked model: box spring, slatted base or solid foundation.

Its own fields disagree with each other. Item Thickness says 27 cm, Item Dimensions say 27 cm, but Item Depth says 28 cm. As a result, the one thing this 6ft super king mattress cannot tell you is exactly how deep it is. No coil count is published anywhere either — unusual for a listing that leans so hard on its spring unit.

Slily 12 Inch Pocket Sprung Hybrid Mattress, 30 cm

12 inch super king mattress 180x200 with 30 cm depth and reinforced edges
£220.99 4.5 1,077 reviews

Claims 2,000 pocket springs at £220.99 — ten times the £829 model's count — alongside a 17 g item weight.

Pros

  • Claims 2,000 pocketed coils, the highest count in this set
  • 250 kg maximum weight capacity, the highest published here
  • 30 cm depth, alongside the NOFFA the deepest hybrid in the ranking
  • Reinforced dual-row edge support
  • 4.5 stars from 1,077 ratings

Cons

  • Firmness field says Medium while the title says Medium Firm

“I've been really pleased with this mattress so far. It has a good balance of comfort and support, and the medium firm feel suits me well. The memory foam layer feels comfortable without being too soft, while the pocket springs provide good support. I also like the 7 zone design, which seems to provide a nice level of support across the mattress. It feels well made, and the 30cm depth gives the bed a substantial, comfortable feel.Overall, it's comfortable, supportive and good value for the price. I'm happy with my purchase.”

Check Price on Amazon More about the Slily 12 Inch Pocket Sprung Hybrid Mattress, 30 cm

The headline here is 2,000 pocket springs at £220.99, roughly ten times the £829 model's 600 and more than double the 900 of the top-ranked mattress. Crucially, the same table lists the item weight as 17 g and the item dimensions as 100 x 30 x 30 cm. Neither is possible for a 180x200 mattress. The £143.64 model weighs 38 kg; this one supposedly weighs less than a slice of bread.

It is a 30 cm deep 6ft super king mattress with dual rows of reinforced coils along all four edges, and a published maximum weight capacity of 250 kg — the highest figure in this set. The cover is a 3D knitted fabric. It ships vacuum-sealed and rolled, and the seller asks for two to three days of settling before use.

Buy this if you want the deepest profile and the highest stated weight capacity, not if you want a documented build. The spec table lists only 2 layers while other listings here claim 12. By contrast, the firmness field says Medium while the title says Medium Firm. With a 17 g weight field, nothing in this table can be taken at face value.

TeQsli 9 Inch Pocket Sprung Mattress in a Box, 22 cm

TeQsli 9 inch super king mattress in a box with knitted cover, 22 cm
£139.99 4.4 1,366 reviews

£139.99 for 22 cm and a claimed 12 layers — which averages 1.8 cm per layer, the thinnest here.

Pros

  • £139.99, the lowest price in this ranking
  • 25 kg weight is plausible for a 22 cm pocket sprung build
  • 100-night trial stated in the bullets
  • Dual rows of reinforced coils along the edge
  • Rolled and vacuum-sealed for delivery

Cons

  • Construction Type says Memory Foam while the coil type says Pocketed Coil
  • 12 layers across 22 cm averages 1.8 cm per layer
  • 22 cm is the shallowest profile in this set
  • Fill material field names high density foam only

Check Price on Amazon More about the TeQsli 9 Inch Pocket Sprung Mattress in a Box, 22 cm

£139.99 is the lowest price in this ranking, and the profile is 22 cm — the shallowest hybrid here. It claims 12 layers, which averages 1.8 cm per layer, the thinnest average in this set. Meanwhile the Construction Type field says Memory Foam while the coil type field says Pocketed Coil. The two cannot both describe the same product.

It is a super king pocket sprung mattress rolled and vacuum-sealed into a box, with a knitted fabric cover and a Euro top. Dual rows of reinforced coils run along the edges. It is medium firm, 25 kg, and the listing says it fits box springs, slatted bases and floor beds. A 100-night trial is stated in the bullets.

The catch is depth. At 22 cm it is 8 cm shallower than the two 30 cm models here, and the fill material field names high density foam only — no memory foam appears in that field despite the title. If you want a thick, deep mattress, this is not it. Even so, £139.99 with 25 kg behind it is a believable package.

Doublelife 11 Inch Gel Memory Foam 9-Zone Mattress

Doublelife 11 inch gel memory foam super king mattress, 28 cm deep
£378.99 4.6 249 reviews

The best average in the set at 4.6 from 249 ratings, and the most expensive hybrid before the £829 outlier.

Pros

  • 4.6 average from 249 ratings, the best above 200 ratings in this set
  • 9-zone pocket spring with gel memory foam
  • CertiPUR-US and OEKO-TEX certification stated

  • 3D breathable fabric cover with claimed motion isolation

Cons

  • No coil count published anywhere in the spec table
  • 12 layers across 28 cm averages about 2.3 cm each

This is the highest-rated mattress here at 4.6, from 249 ratings, and at £378.99 it is the most expensive hybrid before the £829 outlier. It declares 12 layers, which across 28 cm averages about 2.3 cm each. No coil count is published, so £378.99 buys a 9-zone spring unit and a certification list rather than a spring number you can compare with anything else.

The build is 9-zone individually pocketed springs with gel memory foam and a 3D breathable fabric cover. The listing claims motion isolation, edge support, and both CertiPUR-US and OEKO-TEX certification. It weighs 28 kg, is medium firm, and carries a 100-night trial. In theory this is the middle of the range: deeper than 25 cm, cheaper than the Dormeo.

That said, 249 ratings is a smaller sample than the top three listings carry, and 4.6 on a small sample is easier to hold than 4.4 on 3,524. Nobody shopping for the cheapest super king mattress should start here — the £143.64 TeQsli lists more springs and costs £235 less. And with no coil count, there is no way to check the £378.99 against the rest.

Pros

  • Layer breakdown adds up exactly: 4 + 4 + 12 cm = 20 cm
  • CertiPUR-US and OEKO-TEX certification stated
  • 21 kg, the lightest mattress in this ranking
  • Washable cover; foam not washable
  • Expansion stated as 20 cm within 24 hours, ± 1 cm

Cons

  • No pocket springs at all
  • 20 cm is the thinnest profile here

Check Price on Amazon More about the NOFFA Soft Super King All-Foam Mattress, 20 cm

This is the only all-foam model in the ranking and, notably, the only one whose layer arithmetic adds up. The bullets describe 4 cm gel memory foam plus 4 cm bamboo charcoal foam plus 12 cm support foam: 20 cm exactly, which matches the size field. Compare that with the listings claiming 12 layers inside 22 cm. At 21 kg it is also the lightest mattress here.

It is a super king size mattress with no springs at all — plush, not medium firm — and the cover is washable while the foam is not. Both CertiPUR-US and OEKO-TEX certification are stated. The listing says it expands to 20 cm within 24 hours of unboxing, with a 1 cm tolerance either way, which is a more specific claim than most listings here make.

Do not buy it if you want spring support, a deep profile, or a medium firm feel. At 20 cm it is the thinnest mattress in this set, 8 cm short of the two 30 cm models. At the same time, £199.99 for a certified all-foam 180x200 with a washable cover is a fair ask, and the firmness is at least honest about being plush rather than pretending to suit everyone.

£169.99 4.5 265 reviews

The item weight field on this listing reads 454 g, for a 25 cm pocket sprung mattress at £169.99. That is the second impossible weight in this set, after the 17 g on the 30 cm model. Every other hybrid here falls between 17 kg and 45.2 kg, and 454 g would make this mattress lighter than a bag of sugar. Its dimensions field also reverses the usual order, giving length as 180 cm and width as 200 cm.

It is a 9-zone pocketed spring build with gel memory foam, sold compressed and rolled, with 48 to 72 hours recommended for expansion and for the packaging odour to clear. Firmness is medium firm, depth is 25 cm, and the cover is a knitted fabric with 3D mesh. The colour field says orange.

No coil count is published, and the weight field cannot be used as a sanity check, which means the spring unit cannot be verified from the page at all. Its histogram also skips two stars entirely: 5 entries at one star, nothing at two, then 6 at three. Worth noting if you read histograms closely.

  • Seller publishes a firmness guide by body weight

  • Listing itself says it may not support users over 100 kg long-term
  • Fill material says feathers and memory foam while material type says springs and memory foam

It's perfect! The quality and attention to detail and build craftsmanship is unbelievable. This should be at least 4x the price.I'm a big guy (16+ stone) and it supports me well, doesn't even flinch and I'm extremely impressed.I would recommend it, even my wife was surprising taken by it, being a sub £200 quid mattress, we thought it would be a temp, as we just moved house, got a new bed frame with built in TV support, and we took a chance on this as an interm solution before we went for a Tempur etc, but honestly, there's no need.Buy it today, before the price skyrockets or stock is gone, you won't be disappointed.

Check Price on Amazon More about the NOFFA 12 Inch 7-Zone Hybrid Mattress, 30 cm

NOFFA's 12 inch hybrid claims 1,000 individually pocketed springs at £259.99 and weighs 41 kg — the second-heaviest item here and consistent with a 30 cm build. It also carries the highest average rating in the set, 4.9, though from just 120 ratings. In short: strong numbers, thin sample.

The unusual part is the firmness guide in the first bullet. The seller states the mattress feels firmer under 70 kg, medium firm between 70 and 80 kg, softer between 80 and 100 kg, and may not give optimal long-term support above 100 kg. That is a rare piece of honesty in a category full of fixed claims. The mattress has 7 support zones, a Euro top, and a 100-night trial.

The listing contradicts itself on fill: one field says feathers and memory foam, while the material type says springs and memory foam. Feathers in a 30 cm hybrid would be unusual, and nothing else on the page mentions them. And if you are over 100 kg, the seller's own guidance is that this super king mattress may not be the right one for you.

“Very pleased with this mattress but was a little surprised how heavy it was to carry upstairs seeing what the construction of it is.But after placing it on the bed i was pleasantly surprised just how comfortable it is.”

Check Price on Amazon More about the Dormeo Octasmart Hybrid Plus Mattress, 22 cm

At £829 this is the most expensive mattress in the ranking and it declares 600 pocket springs — the fewest of any spring count published here. The £143.64 model declares 868; the £220.99 model claims 2,000. That means the cheapest pocket sprung listing here states 45% more springs than the most expensive one does.

What £829 buys is the Octaspring honeycomb system, arranged into 6 body zones, plus a pressure-relieving memory foam layer and a cover the listing claims is 8x more breathable. It weighs 45.2 kg, the heaviest item in this set, with a published maximum user weight of 139 kg. Firmness is medium.

Even so, the numbers behind the price are the weakest here: 4.0 from 68 ratings, the lowest average and the smallest sample in the ranking. Its histogram puts 14 entries at one star and 3 at two — 17% at one or two stars, against 9% for the top-ranked model. Its thickness field says 22 cm while its dimensions field says 24 cm. Buy it for the spring design, not for a spring count.

Final Verdict

For most homes, the TeQsli at £143.64 does the job: 868 pocket springs set against a 38 kg item weight, in a super king mattress in a box that fits through a narrow hallway. If you want more depth and a stated trial, the dosleeps at £269.99 lists 900 coils, 28.5 kg and a 100-night trial. However, if firmness needs to change with your body weight, only the NOFFA 12 inch hybrid publishes that guide — and, crucially, it also says it may not support users over 100 kg. Either way, treat the super king mattresses here as sets of claims to check, not finished specifications: the £829 model asks the most and declares the fewest springs.

Best Electric Cool Box 2026: 10 Ranked, and Why the Litre Count Misleads

An electric cool box is sold on one number, and it is the least reliable figure in the listing. The TZS 25-litre model calls itself a '32-litre gross capacity (25L net)' in its own bullet point. The TZS with wheels is a 40L box in the title and a 45L box in the bullet and the specification. The Igloo IE27 is 26 litres in the title, 27 litres in the bullet and on the spec sheet. Only the Amazon Basics box publishes both measurements without contradicting itself: 24L total, 22L net. So count on two to five of the litres you are paying for being the outside of the box rather than the space you can fill. We ranked ten of the best electric cool boxes on Amazon on things we could actually check: the listed price, the number of ratings behind each score, and the places where a specification disagrees with its own marketing copy. Thermoelectric and compressor designs sit in the same list, and they are not interchangeable. One cools to a fixed number of degrees below the air around it; the other holds a temperature you choose.

Best Baby Changing Bag 2026: 10 Ranked, Pocket Counts Checked

Pocket counts are the number that sells a baby changing bag, and in four of the ten listings below the same page gives two different figures. The Dikaslon announces 19 pockets in its title while its own specification table says 18. The NEWHEY says 14 in the description and 15 in the specs. The £19.99 LOVEVOOK claims 20 pockets in the description, and the specification table lists 5. The black BabbleRoo lists 11 pockets against 9 on its grey twin. The clearest unloaded figure comes from the £33.99 LOVEVOOK: it declares 30 litres of volume, but its own dimensions — 30 x 10 x 45 cm — multiply to 13.5 litres. Meanwhile the same 26-litre BabbleRoo costs £31.97 in light grey and £37.99 in black, £6.02 apart for the same bag. We ranked ten of the best baby changing bags on Amazon on verified price, rating, review volume, and whether each listing's own numbers agree with each other. Where they do not, we say so with both figures.

Best Work Lights 2026: 10 Ranked, 4 Listings That Argue With Themselves

Two listings in this round-up claim 4,000 lumens and 2,000 lumens in their titles. Their own spec tables and bullets say 3,000 and 1,000. That gap is the reason this guide exists: the best work lights are not the ones with the biggest number on the box, but the ones whose numbers survive cross-checking. Across these ten listings the headline figure and the specification table disagree four times. The SYLSTAR 40W is titled 4,000LM while its own Light Output Maximum field reads 3,000 Lumens — the same figure its cheaper 30W sibling quotes. The LETOUR two-pack advertises 2,000 lumens in the title and 1,000 lumens in its own first bullet. The wattage fields repeat the trick: the OHAYORI declares 60 watts against a 30-watt Maximum Compatible Wattage, and the SYLSTAR 100W declares 100 watts against 50 watts. Below, we ranked ten of the best work lights on Amazon on four honest checks: whether the lumens in the title match the Light Output Maximum field; runtime and battery capacity against the modes claimed; price per usable light; and how many ratings sit behind the star score. Where a listing argues with itself, we print both numbers rather than pick the kinder one. In practice, that is why the £55.99 rechargeable floodlight ranks third and not first, and why a £15.67 portable work light at number eight carries the highest star score here.
