# Best Super King Mattress 2026: 10 Ranked, One Claims 2,000 Springs Source: https://www.ranked10.co.uk/home/best-super-king-mattresses Published: 2026-09-19 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-19 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. ## The ranking ### 1. dosleeps 6FT Hybrid Memory Foam Mattress, 10 Inch - Price: £269.99 | Amazon rating: 4.4 from 3,524 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/dosleeps-super-king-hybrid-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0FM2V3XDH?tag=ranked10-21 Top of the ranking on 3,524 ratings and a 900-coil unit that matches its own 28.5 kg weight. 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. Pros: 900 pocketed coils at £269.99 — 300 more than the £829 model declares; 28.5 kg item weight is consistent with a hybrid of this size; Tencel lyocell cover, described as moisture-absorbing; 100-night trial included; Compatible with box spring, slatted base and solid foundation Cons: Medium firm is the only firmness listed; 7 layers across 25 cm averages about 3.6 cm per layer; Cover is a polyester blend and needs a gentle cycle; 9 of 100 histogram entries sit at one or two stars ### 2. TeQsli 10 Inch Hybrid Pocket Sprung Mattress, 180x200 - Price: £143.64 | Amazon rating: 4.5 from 1,412 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/teqsli-super-king-hybrid-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0BR8TSKVQ?tag=ranked10-21 The cheapest here at £143.64, declaring 868 pocket springs — 268 more than the £829 model. 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. 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 ### 3. dosleeps 10.6 Inch 9-Zone Super King Mattress, 27 cm - Price: £259.99 | Amazon rating: 4.4 from 2,686 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/dosleeps-super-king-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0FNBV1KR7?tag=ranked10-21 Second dosleeps in the top three, and its own fields disagree on depth: 27 cm in three places, 28 cm in a fourth. 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. 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 ### 4. Slily 12 Inch Pocket Sprung Hybrid Mattress, 30 cm - Price: £220.99 | Amazon rating: 4.5 from 1,077 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/slily-super-king-hybrid-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0D4Q37Y6Y?tag=ranked10-21 Claims 2,000 pocket springs at £220.99 — ten times the £829 model's count — alongside a 17 g item weight. 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. 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: Item weight listed as 17 g; Item dimensions listed as 100 x 30 x 30 cm; Only 2 layers in the spec table against 12 elsewhere; Firmness field says Medium while the title says Medium Firm ### 5. TeQsli 9 Inch Pocket Sprung Mattress in a Box, 22 cm - Price: £139.99 | Amazon rating: 4.4 from 1,366 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/teqsli-super-king-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0GXZF4B6B?tag=ranked10-21 £139.99 for 22 cm and a claimed 12 layers — which averages 1.8 cm per layer, the thinnest here. £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. 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 ### 6. Doublelife 11 Inch Gel Memory Foam 9-Zone Mattress - Price: £378.99 | Amazon rating: 4.6 from 249 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/doublelife-super-king-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0GF82SYSJ?tag=ranked10-21 The best average in the set at 4.6 from 249 ratings, and the most expensive hybrid before the £829 outlier. 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: 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; 100-night trial included; 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; £378.99 is nearly double the £199.99 all-foam option; 249 ratings is a smaller sample than the top three listings ### 7. NOFFA Soft Super King All-Foam Mattress, 20 cm - Price: £199.99 | Amazon rating: 4.5 from 370 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/noffa-soft-super-king-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0GQ9KQ1JB?tag=ranked10-21 The only all-foam model here, and the only one whose layer arithmetic adds up: 4 + 4 + 12 cm = 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. 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; Plush firmness will not suit anyone wanting medium firm; Only 370 ratings, a smaller sample than the top three ### 8. SCEPKN 9-Zone Gel Memory Foam Mattress, 25 cm - Price: £169.99 | Amazon rating: 4.5 from 265 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/scepkn-super-king-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0FPCWDXQ4?tag=ranked10-21 £169.99 with a 454 g item weight — the second listing here whose weight field is out by three orders of magnitude. 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. Pros: 9-zone pocketed spring design with gel memory foam; £169.99, below both dosleeps listings; 25 cm depth, matching the top-ranked model; 4.5 stars from 265 ratings; 3D breathable mesh and knitted fabric cover Cons: Item weight listed as 454 g; Item dimensions give length as 180 cm and width as 200 cm, reversed against every other listing here; No coil count published; Histogram has no two-star entries at all ### 9. NOFFA 12 Inch 7-Zone Hybrid Mattress, 30 cm - Price: £259.99 | Amazon rating: 4.9 from 120 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/noffa-6ft-super-king-hybrid - Buy on Amazon: https://www.amazon.co.uk/dp/B0GQ9176Y5?tag=ranked10-21 4.9 from 120 ratings — the highest average here — and the only listing that admits firmness changes with your weight. 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. Pros: 1,000 individually pocketed springs; 41 kg weight is consistent with a 30 cm hybrid build; Seller publishes a firmness guide by body weight; 4.9 average from 120 ratings; 100-night trial and 7-zone support Cons: Only 120 ratings, the second-smallest sample here; 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; 1,000 coils is half the 2,000 claimed by the £220.99 model ### 10. Dormeo Octasmart Hybrid Plus Mattress, 22 cm - Price: £829.00 | Amazon rating: 4.0 from 68 ratings - Full review: https://www.ranked10.co.uk/home/best-super-king-mattresses/dormeo-octasmart-hybrid-plus - Buy on Amazon: https://www.amazon.co.uk/dp/B09MR29DKW?tag=ranked10-21 The most expensive at £829, with the fewest springs — 600 — and the lowest rating in this set at 4.0. 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. Pros: 45.2 kg, the heaviest item in this set; 6 body zones using the Octaspring honeycomb design; 139 kg maximum user weight published; Hypoallergenic and temperature regulating per the special features; Medium firmness Cons: £829, the highest price, with the lowest coil count at 600; 4.0 average from 68 ratings, the lowest in this ranking; 17% of histogram entries at one or two stars, against 9% for the top-ranked model; Thickness says 22 cm while the dimensions field says 24 cm; Only 2 layers in the spec table ## 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.
