Best Double Mattress 2026: 10 Ranked, and Where the Spec Sheets Disagree

3,524 ratings at 4.4 put this first. The next-biggest sample in this list is 439, so more buyers have left a verdict on this mattress than on the other nine combined. Crucially, it also declares 650 individually pocketed coils across nine zones — the highest coil figure of any mattress here, at the same £149.99 as the Amazon Basics, which declares 350.

In practice it is a 25 cm hybrid: gel memory foam and wave memory foam over a 9-zone pocket spring unit, with a Tencel Lyocell surface that the listing says absorbs moisture more efficiently than standard fabric. The foam layer is claimed to cut pressure on neck, spine and hips by up to 87%. A 100-night trial is stated in the bullets, and the base compatibility list covers box springs, slatted bases and solid foundations.

That said, 4.4 is the joint-lowest score in this top ten, and 9% of the ratings shown sit at one or two stars. The dimensions also carry three different numbers: the size field says 25 cm, the thickness field says 10 inches (25.4 cm) and the item depth says 24 cm. If you need a declared weight limit, this double mattress does not give one.

439 ratings at 4.6 put this second, and the 30 cm build makes it the deepest double mattress here — 5 cm more than the 25 cm and 26 cm models that dominate the list. At £161.49 it is the third most expensive. However, that extra depth costs weight: 27.6 kg is beaten only by the NIXNAP at 28.5 kg, which is 5 cm thinner.

It is a 4ft6 double mattress in the standard 135 x 190 cm footprint, built as a four-layer pocket spring unit with cooling foam and a moisture-wicking fabric. The listing claims 30,000 pressure tests behind its VAJRA spring system and says the mattress expands fully in 72 hours after unboxing. Meanwhile, one bullet says it is fully expandable in 10 seconds — those two numbers cannot both be right. Delivery is vacuum-sealed and rolled.

The catch for heavier users: no spring count appears anywhere on this listing, unlike the 650, 630 and 350 declared by cheaper rivals. It also states the handle is for decoration only, so you will not be dragging it upstairs by that. And 30 cm needs deep-pocket sheets; a standard 25 cm sheet will not stay on.

136 ratings at 4.7 — one of only two 4.7 scores in this list — at £139.99. That is £10 less than the dosleeps and the FRIDEKO, both of which declare spring counts this listing does not. 79% of its ratings are five-star. At the same time, the sample is small: the top-ranked mattress has 26 times as many.

This hybrid double mattress runs pocket springs for spinal support alongside comfort foam, with a gel-infused top layer intended to draw heat away. The reinforced perimeter is the practical detail: it gives you a stable edge to sit on and adds usable sleeping surface. Expansion takes 48 to 72 hours after unboxing, and it is compatible with slatted bases and box springs.

Worth noting what the listing leaves out. There is no coil count, no weight capacity, and the cover material field simply says Fabric, material not specified. Nor is there any CertiPUR-US or OEKO-TEX mention, unlike the FRIDEKO, NIXNAP and Happiland. With 136 ratings, the sample is also a tenth the size of the one behind the top-ranked double mattress.

630 individually wrapped springs across seven zones, £149.99, 4.6 from 98 ratings. In theory that is near-identical to the 650 springs of the top-ranked mattress at the same price. The difference is the evidence: 98 ratings against 3,524. By contrast, this one does name its certifications — CertiPUR-US foam and OEKO-TEX Standard 100 fabric.

The build is a 25 cm hybrid with gel-infused memory foam over the pocket spring unit, and a bamboo charcoal cover the listing describes as naturally hypoallergenic. Motion isolation is the headline claim: the coils are independently wrapped, so a partner's movement stays local. It fits box springs, bunky boards, slatted bases and foundations, and the care instructions are spot-clean only rather than machine wash.

Even so, 98 ratings is a small sample for a £149.99 purchase, and three of them are one-star. No weight capacity is declared, and no individual layer thickness is given, so the 10-layer figure in the specs does not tell you how thick the memory foam actually is. If you want a long track record rather than a good specification sheet, this is not the one.

£110.49, 4.6 from 108 ratings, and the only mattress in this list with a declared weight capacity: 250 kg. It is also the heaviest of the 25 cm group at 28.5 kg. So you get the second-lowest price with the highest stated load, which is an unusual combination in a category where cheap usually means thinner springs.

Nine zoned pocket spring sections sit under cooling memory foam and a breathable 3D fabric, with reinforced edges. A 100-night trial is stated, along with a 72-hour expansion window. The spring count is not given, which means the 9-zone claim describes layout rather than density — you cannot compare it numerically with the 650 or 630 coil counts elsewhere in this list.

The dimension fields disagree with each other. The highlight says 135 x 200 x 25 cm; the size field says Double, 135 x 190 cm. One of those is wrong, and it matters by 10 cm. Firmness is listed as Medium in the specs but as medium-firm in the bullets, so check both before you buy this double mattress. On top of that, the care instruction is hand wash only, for a 28.5 kg object.

242 ratings at 4.5 make this the third-largest sample in the list, at £169.99 — the second-highest price here. Yet its own specification describes two different mattresses: the size field says Double (135x190cm), the item dimensions say 200 x 140 cm. It also lists one layer and a construction type of Memory Foam, while the bullets describe a seven-zone pocket sprung hybrid.

Anyone searching for a double mattress 135x190 will find the right size field and a contradictory one underneath, so measure your frame before ordering. The practical build, as described, is a fan-quilted surface over seven pocket spring zones with breathable knit fabric and motion isolation. It arrives compressed and rolled, with 24 to 72 hours allowed for expansion, and it cannot be re-rolled once opened.

At £169.99 it is £30 more than the FRIDEKO, which declares 630 springs, and it names no spring count at all. Firmness is given as Medium in the specs, Firm in the style name and medium to firm in the bullets. As a result, the one thing you know for certain is the price.

£117.79, 4.6 from 73 ratings, 25 cm and 17 kg. The number that stands out is the coil count: 71. The next-lowest declared figure in this list is 350 on the Amazon Basics, which costs £32 more. A 25 cm pocket sprung hybrid with 71 springs would be unusual, so read that figure as a data-entry problem rather than a build specification — we report what the listing says.

You get it as a double mattress in a box: vacuum-compressed, sealed and rolled, with 72 hours advised before use. The fill is listed as memory foam and cotton, with a breathable hypoallergenic cover and independently bagged springs for motion isolation. Country of origin is China.

At the same time, 73 ratings is a small base, and the listing gives no certifications, no weight capacity and no split between the memory foam and the cotton. Fill proportions matter on a mattress this thin. If spring density is what you are paying for, the 630-spring FRIDEKO is £32 more.

£109.98 buys more here than anywhere else in the top ten: a 25 cm hybrid, seven-zone pocket springs, memory foam and a 4.7 rating. The catch is the sample — 46 ratings, the smallest in this list. Notably, not one of them is one-star or two-star. Separately, its declared weight of 10.9 kg is the anomaly that shapes this whole article: every other 25 cm mattress here is listed at 23.9 kg to 28.5 kg.

The build is a seven-zone individually pocketed spring unit under high-density memory foam, with a 3D breathable mesh side panel and a Euro Top finish. The listing names both CertiPUR-US foam and OEKO-TEX Standard 100 certification, which is more than the Tegeniss and Hiimgo offer. It ships vacuum-compressed and rolled, with 72 hours allowed for recovery.

Two things to weigh. First, 46 ratings is thin, however good they look. Second, the 10.9 kg figure — if accurate, this is a very different construction from the 23.9 kg to 28.5 kg memory foam double mattress sitting around it in this ranking; if it is a listing error, then the weight column of this comparison is unreliable. Either way, do not pick it on weight.

£149.99 buys 350 pocketed coils here. The dosleeps costs the same £149.99 and declares 650. That is nearly double the spring count for identical money, and it is the clearest price-per-spring gap in this list. The rating is 4.2 from 124 reviews, the joint-lowest score in the ranking.

At 22 cm this is the thinnest mattress here, and its firmness is listed as Plush where almost everything else is medium or medium firm. Meanwhile, it is the only pocket spring double mattress in this list rated plush, which suits some sleepers and rules it out for others. It is made in the UK, certified BS7177-compliant, and weighs 27 kg — heavier than several mattresses that are 3 cm thicker.

The histogram is the warning: 12% of ratings are one or two stars, the largest low-rating share in this top ten. If you want a medium-firm feel, or springs you can count on, this is not the one. It also carries no CertiPUR-US or OEKO-TEX claim, and the care instruction is hand wash only.
