# Best Small Double Mattress 2026: 10 Ranked, Coil Counts Compared Source: https://www.ranked10.co.uk/home/best-small-double-mattresses Published: 2026-09-19 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-19 The spring count should be the number that separates one small double mattress from another. In practice, it is the least trustworthy figure in the category. Twirest's own data sheet logs 7 coils for a 7-zone spring unit. BEDZONLINE logs 150 Bonnell coils. Meanwhile dosleeps claims 700 and Vesgantti 390 in the same 120x190cm footprint. Thickness is no safer. BEDZONLINE's title says 20cm, its spec sheet says 6 inches (15.2cm), and the same listing gives the mattress dimensions as 26 x 26 x 101cm. We ranked ten of the best small double mattress options on Amazon on three honest measures: whether the spec sheet agrees with the listing it sits under, how many buyers actually left a rating, and what you pay per centimetre of depth. Where a brand contradicts itself, we quote both numbers. ## The ranking ### 1. Vesgantti Hybrid Small Double Mattress, 26cm - Price: £214.99 | Amazon rating: 4.6 from 5,252 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/vesgantti-small-double-hybrid - Buy on Amazon: https://www.amazon.co.uk/dp/B075ZQS29L?tag=ranked10-21 Ranked first for the 10-year warranty and 100-night trial — the longest cover here — at 26cm deep and £214.99. Vesgantti tops this list on cover, not on coils. The spec table logs 390 pocket coils in a 120x190cm frame and 26cm of depth, against a 4.6 average from 5,252 ratings — 77% of them five stars. However, it is also the priciest small double mattress here at £214.99, £75 more than the 700-coil dosleeps at 22cm. The build is a 7-zone pocket spring unit under memory foam, boxed and vacuum-sealed at 26.7kg. Crucially, that weight matters: a 26cm hybrid is not a mattress you turn alone, and Vesgantti's care instructions say hand wash only for the cover — not something most buyers will ever do. Don't buy this if price leads your decision. It costs £106 more than the SZsuilong at 28cm, and the listing gives thickness as both 26cm and 10.3 inches (26.2cm). The 10-year warranty and the 100-night trial are the real reasons it sits first. Pros: 390 pocket coils in a 120x190cm frame — the second-highest count here; 4.6 from 5,252 ratings, with 77% at five stars; 100-night trial and 10-year warranty, the longest cover in this list; 26cm deep and 26.7kg, the heaviest build in the top five; CertiPUR-US and OEKO-TEX certified materials stated Cons: £214.99, the most expensive here — £75 more than the £139.99 dosleeps; Care instructions say hand wash only, which is impractical for a mattress cover; Thickness is given as both 26cm and 10.3 inches (26.2cm) in the same listing; No coil count in the bullet points; 390 appears only in the spec table ### 2. TeQsli 4FT Small Double Hybrid Mattress, 25cm - Price: £129.19 | Amazon rating: 4.4 from 1,967 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/teqsli-small-double-pocket-spring - Buy on Amazon: https://www.amazon.co.uk/dp/B0DSBRWGJT?tag=ranked10-21 Second for the highest coil count below £130 — 522 pocket springs — plus the highest stated weight capacity here at 600lb. TeQsli takes second on one number: 522 pocket coils for £129.19. That is more coils than the £214.99 Vesgantti and roughly £0.25 per coil. Meanwhile the 600lb (272kg) maximum weight is the highest capacity stated anywhere in this list. The 25cm hybrid packs a 7-zone pocket spring unit, cooling memory foam and 3D mesh side panels into 22kg. In practice, that 12-layer count in the spec is marketing — the fill material field names five things: pocket springs, cotton felt, high density foam, memory foam and non-woven fabric. That said, the review profile is mixed. Of 1,967 ratings, six are one star and three are two stars. There is no trial period and no warranty length in the listing either, which the Vesgantti and both dosleeps models do state. If you want the most spring per pound, this small double hybrid mattress is still the value pick. Pros: 522 pocket coils — the highest count in this list below £130; 600lb (272kg) maximum weight, the highest capacity stated here; 25cm deep and 22kg, lighter than the 26.7kg Vesgantti; Handles and edge support both listed as special features; £129.19, about £85 less than the top pick Cons: 4.4 stars from 1,967 ratings, with nine reviews at two stars or below; No trial period or warranty length stated, unlike the Vesgantti and dosleeps; 12 layers is stated but never broken down in the spec table; Allow 72 hours to expand, at the long end of the 24-72 hour range other brands quote ### 3. dosleeps 9-Zone Small Double Mattress, 25cm - Price: £139.99 | Amazon rating: 4.4 from 3,524 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/dosleeps-small-double-hybrid - Buy on Amazon: https://www.amazon.co.uk/dp/B0FB9BP956?tag=ranked10-21 Third on review volume — 3,524 ratings at 4.4 — with 550 pocket coils, though its own specs give the depth three different ways. Third place goes to the 25cm dosleeps, which logs 550 pocket coils across 9 zones and 3,524 ratings at 4.4 — the second-largest review base here. As a small double pocket sprung mattress goes, that is a lot of spring for £139.99. The build pairs gel memory foam with individually wrapped coils, a Tencel cover and a 3D mesh side panel, at 21.7kg. The brand claims the foam cuts pressure on neck, spine and hips by up to 87%. Worth noting: that is a manufacturer figure, not a test result, and nothing in the listing explains how it was measured. By contrast, the internal numbers are messy. The same spec table gives the depth as 24cm, the thickness as 10 inches (25.4cm) and the size as 120x190x25cm. Nine of its 3,524 ratings are two stars or lower, and no warranty length appears anywhere in the listing. Pros: 550 pocket coils across a 9-zone spring unit; 3,524 ratings at 4.4 — the second-largest review base here; 100-night sleep trial stated in the bullets; Tencel fibre cover, claimed to absorb moisture more efficiently; 21.7kg, one of the lighter hybrids at this depth Cons: Its own spec table gives depth as 24cm, thickness as 10 inches and size as 25cm; The 87% pressure-reduction figure is a brand claim, not a measured test; No warranty length is stated anywhere in the listing; Nine of its 3,524 ratings are two stars or lower ### 4. dosleeps 9-Zone Small Double Mattress, 22cm - Price: £139.99 | Amazon rating: 4.5 from 784 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/dosleeps-small-double-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0FCSK6284?tag=ranked10-21 Fourth for the highest coil count in the whole list — 700 — in a slimmer 22cm body at the same £139.99. Fourth on the highest coil count anywhere in this shortlist: 700 pocket springs, in the 22cm dosleeps at £139.99. It also carries the best rating of the three dosleeps entries — 4.5 from 784 ratings, 78% at five stars. The 9-zone design uses the same gel memory foam and 3D breathable fabric as its 25cm sibling, but 3cm thinner and 20kg rather than 21.7kg. Curiously, the thicker mattress claims 550 coils and this thinner one claims 700 — a 27% jump that no part of either listing explains. Even so, this is the thinnest of the three dosleeps models, and 784 ratings is the smallest sample in the top five. It repeats the same 12-layer line with no breakdown, and no warranty period. Buy it for the spring count and the 100-night trial, not for depth. Pros: 700 pocket coils — the highest count of any mattress here; 4.5 stars from 784 ratings, with 78% at five stars; 22cm deep and 20kg, the lightest of the dosleeps entries; 100-night sleep trial stated; CertiPUR-US and OEKO-TEX listed in the benefits field Cons: 784 ratings is the smallest sample in the top five; £139.99 buys 700 coils here but 550 in the 25cm dosleeps — the count does not scale with depth; 12 layers is stated but never itemised; No warranty length given ### 5. Inofia Original Series Small Double Mattress, 26cm - Price: £138.69 | Amazon rating: 4.6 from 2,472 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/inofia-small-double-mattress-26cm - Buy on Amazon: https://www.amazon.co.uk/dp/B0C27YBY4P?tag=ranked10-21 Fifth for consistency — 4.6 from 2,472 ratings at £138.69 — though Inofia publishes no coil count at all. Fifth for consistency: 4.6 from 2,472 ratings, 77% at five stars, and £138.69 for a 26cm hybrid. If you want a small double memory foam mattress with springs behind it, this is the same depth as the £214.99 top pick for £76 less. Inofia builds a memory foam and pocket spring hybrid with a Euro Top finish, reinforced edge coils and a SmartAir knitted cover certified to BS7177 for fire resistance. The foam carries EuroPUR and CertiPUR-US certification. At 22.7kg it is lighter than the Vesgantti despite matching it for depth. The catch is the paperwork. This is one of three listings here that publishes no coil count at all, so the support cannot be compared. Firmness is listed as Firm, Medium in the spec and Medium Firm in the highlight. Two bullets also refer to a king mattress, which suggests copy carried over from another size. Pros: 4.6 from 2,472 ratings, with 77% at five stars; £138.69 for a 26cm hybrid — the same depth as the £214.99 top pick; BS7177 fire compliance and EuroPUR/CertiPUR-US foam certification both stated; Euro Top construction with reinforced edge coils; 100-night home trial offered Cons: No coil count published anywhere in the listing; Firmness given as Firm, Medium in the spec and Medium Firm in the highlight; Two bullets refer to a king mattress, not this 4ft size; The 2-4 week adjustment period is the longest settling advice here ### 6. dosleeps Medium Firm Small Double Mattress, 27cm - Price: £153.69 | Amazon rating: 4.4 from 2,686 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/dosleeps-small-double-mattress-j47z - Buy on Amazon: https://www.amazon.co.uk/dp/B0FBDNJ47Z?tag=ranked10-21 Sixth for depth at 27cm, but this is the most expensive dosleeps and it publishes no coil count to compare. Sixth on depth: 27cm, the third-thickest here, for £153.69. That is the most expensive dosleeps in this list and £14 more than the 25cm version, yet the listing publishes no coil count at all. If you specifically want a small double mattress medium firm in feel, the spec says medium firm and the top layer is gel memory foam over 9-zone pocket springs. The cover is a 3D breathable quilted knit, and the whole thing weighs 22kg — lighter than the 26cm Vesgantti, despite being 1cm deeper. That said, £153.69 buys nothing measurable that the £139.99 dosleeps does not also claim. Eight of its 2,686 ratings are one star. The 12-layer figure appears again with no itemised breakdown, so treat it as a label rather than a specification. Pros: 27cm deep — 5cm more than the 22cm dosleeps at the same brand; 4.4 from 2,686 ratings; Gel memory foam top layer over 9-zone pocket springs; 100-night sleep trial stated; 22kg, lighter than the 26cm Vesgantti at 26.7kg Cons: No coil count published, so the 9-zone claim cannot be checked; £153.69 is the most expensive dosleeps here and £14 more than the 25cm one; Eight one-star ratings out of 2,686; 12 layers is stated but never itemised ### 7. Suilong 12 Inch Small Double Hybrid Mattress, 30cm - Price: £139.99 | Amazon rating: 4.6 from 585 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/suilong-small-double-mattress-4ft - Buy on Amazon: https://www.amazon.co.uk/dp/B0DPRWR37M?tag=ranked10-21 Seventh despite being the thickest at 30cm, because the listing gives two different sets of dimensions. Seventh for a reason that has nothing to do with comfort: Suilong's own spec table gives the dimensions as 28 x 200 x 28cm, while the title and the size field both say 120 x 190 x 30cm. A 200cm length is not a 4ft small double. As a result, the one measurement you need before ordering is the one the listing gets wrong. In theory this is the most mattress here: 30cm deep, 30.5kg, a 250kg weight capacity and a 7-zone pocket spring unit under gel memory foam. It rates 4.6 from 585 ratings, 79% of them five stars, and there is a 100-night trial. The catch is weight and sample size. At 30.5kg it is the heaviest mattress in this list — impractical to rotate alone, which the care instructions ask you to do seasonally. And 585 ratings is a small base next to the 5,252 of the top pick. Buy it if you need the depth; measure your frame first. Pros: 4.6 stars from 585 ratings, with 79% at five stars; 30cm deep — the thickest mattress in this list; 250kg maximum weight capacity; 7-zone pocket springs with reinforced perimeter coils; 100-night sleep trial stated Cons: The spec table gives dimensions as 28 x 200 x 28cm, contradicting the 120x190x30cm in the title; 30.5kg is the heaviest here — awkward to rotate alone; 585 ratings is a small sample next to the 5,252 of the top pick; No coil count published for the 7-zone spring unit ### 8. SZsuilong 4ft Small Double Mattress, 28cm - Price: £106.24 | Amazon rating: 4.5 from 256 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/szsuilong-4ft-small-double-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0G11GQTKS?tag=ranked10-21 Eighth for price — £106.24 and 28cm deep — on a review base of only 256. Eighth for value at depth: £106.24 buys a 28cm hybrid, 2cm more than the £214.99 top pick at roughly half the price. This 4ft small double mattress is also the second-cheapest entry here, behind only the £84.99 BEDZONLINE. It uses 7-zone carbon steel pocket springs with a wave foam breathable layer and a vintage embroidered jacquard cover, at 19.2kg. That is light for a 28cm hybrid and manageable for one person to move on their own. The rating is 4.5, with 81% of 256 ratings at five stars. Even so, 256 ratings is the smallest review base in this list, and seven of them are one star. The spec line also reads 28L x 120W x 190Th, which swaps length and thickness. No coil count is published, so the 7-zone claim cannot be checked. Pros: £106.24 for a 28cm hybrid — the second-cheapest here; 4.5 stars, with 81% of 256 ratings at five stars; 19.2kg — light enough for one person to move; Reinforced edge support stated; 7-zone pocket springs in carbon steel Cons: 256 ratings is the smallest sample here, and seven are one star; The spec line reads 28L x 120W x 190Th, swapping length and thickness; No coil count given for the 7-zone spring unit; 100-night trial offered, but no warranty period is stated ### 9. Twirest Hybrid Small Double Mattress, 22cm - Price: £119.99 | Amazon rating: 4.8 from 162 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/twirest-small-double-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B0FZQ2B2NH?tag=ranked10-21 Ninth, and the clearest example of the problem — its spec sheet logs 7 coils for a 7-zone unit, one coil per zone. Ninth, and the cleanest example of why coil counts cannot be trusted. Twirest's spec sheet logs 7 mattress coils for a 7-zone unit — one coil per zone. It sits among listings quoting 390, 550 and 700 in the same 120x190cm frame. Which means the figure is a data-entry placeholder, not a spring count. The numbers that are consistent look better. Twirest rates 4.8, the highest average here, on a 22cm hybrid with a 250kg capacity and 21kg of weight. The 7-zone inner spring unit is designed to spread weight, and the cover is listed as breathable and hypoallergenic. That said, 4.8 comes from 162 ratings — by far the smallest sample in this shortlist. The fill material field names high density foam only, with no memory foam, despite the hybrid label. No trial period and no warranty length appear in the listing. If a small double mattress 120x190 with a high score appeals, ask what those 7 coils actually are. Pros: 4.8 stars — the highest average rating in this list; 22cm deep with a 250kg maximum weight capacity; £119.99, around £95 less than the top pick; 7-zone spring design with pressure relief listed; Hypoallergenic and dust mite protection stated Cons: 162 ratings — the smallest review base here; The spec sheet logs 7 coils for a 7-zone unit, one per zone; Fill material is high density foam only, with no memory foam named; No trial period or warranty length stated ### 10. BEDZONLINE Hybrid Small Double Mattress, 4ft - Price: £84.99 | Amazon rating: 4.0 from 7,069 ratings - Full review: https://www.ranked10.co.uk/home/best-small-double-mattresses/bedzonline-hybrid-small-double-mattress - Buy on Amazon: https://www.amazon.co.uk/dp/B06X3Q9FJL?tag=ranked10-21 Tenth because its own listing contradicts itself on thickness, though it has the largest review base at 7,069 and the lowest price at £84.99. Tenth because it is the only mattress here whose own listing disagrees with itself on size. The title says 20cm thick. The spec sheet says 6 inches (15.2cm). The dimensions field reads 26 x 26 x 101cm — and a 101cm side is not a mattress. Meanwhile the size field says 4ft small double, and the 150 Bonnell coils are the only spring figure given. It is, however, the cheapest entry at £84.99 and the most reviewed by a wide margin: 7,069 ratings at 4.0. If you need a cheap small double mattress for a guest room, that volume of feedback is worth something. At 13kg it is the lightest here and simple to turn. The compromise is the spring type. Bonnell coils are wired together, not individually pocketed, so motion transfer is higher than in any hybrid above this. Its 4.0 average is the lowest in the list, and 17 ratings are two stars or lower. At the same time, £84.99 is the only price here under £100. Pros: £84.99 — the cheapest here by more than £20; 7,069 ratings, the largest review base in this list; 13kg, easy for one person to carry and rotate; Bonnell spring unit with memory foam, 150 coils stated; Vacuum-packed and roll-packed, expands within 72 hours Cons: 4.0 stars — the lowest average rating here, with 17 ratings at two stars or lower; The title says 20cm, the spec says 6 inches (15.2cm), and the dimensions read 26 x 26 x 101cm; Bonnell coils rather than pocket springs, so motion transfer is higher; Memory foam is the only fill material named, with no layer depth given ## Verdict For most homes, this small double mattress shortlist points to the dosleeps 22cm at £139.99: 700 pocket coils, a 100-night trial, and £75 less than the top pick. If you want the longest cover, the Vesgantti adds a 10-year warranty and 100 nights for £214.99. If you need a cheap small double mattress for a spare room, the BEDZONLINE at £84.99 has the largest review base here — check the depth before you order. Either way, treat any small double mattress coil count as a claim, not a measurement.
