Rank #7 in Best Small Double Mattress 2026: 10 Ranked, Coil Counts Compared
Suilong 12 Inch Small Double Hybrid Mattress, 30cm
Price and rating as shown on Amazon when we collected them. Both change.
Suilong's small double is the seventh entry in this guide: a 4ft (120 x 190cm) hybrid mixing gel memory foam with pocketed coils, at £139.99 with 4.6 stars from 585 ratings. It is the only mattress in this top ten that never states how many springs it contains. Instead of a coil count, the listing offers "7 zones" — a description of how the coils are arranged, not how many there are. If the point of this guide is comparing spring counts across mattresses in the same footprint, this is the listing that gives you nothing to compare against.
The same listing also disagrees with itself on size. One field says 120 x 190cm and the title says 4ft by 6ft3; a separate "item dimensions" field says 28 x 200 x 28cm — 200cm long and 28cm wide on one reading, against 190cm long and 120cm wide on another. Thickness is steadier: 12 inch in the title, 30cm in the spec sheet, which is 11.8 inch. Everything on this page comes from the Amazon listing as we found it, not from a mattress we have slept on or measured.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“The mattress is absolutely amazing. This is the best spent money recently. It is exactly what I expected. I bought it to replace an old one and wanted a moderate hard mattress with orthopedic features. My back feels very well, my sleep is perfect and now 3weeks after the purchase I feel more and more happy with it. Strongly recommend it. Reasonable price and good quality.”
Verified purchase“Second time buying this mattress, and it's just as comfortable as ever! It arrives compact and vacuum-sealed, then expands nicely once opened. It's lovely and plump, really comfortable and feels great to sleep on. Brilliant value and I'd definitely recommend it!”

Questions people ask
How many springs does the Suilong small double mattress have?
The Amazon listing does not give a spring count. It says the pocketed coils are arranged in 7 zones, but no total number of coils appears anywhere in the data.
How thick is it?
The title says 12 inch and the spec sheet says 30cm, which is 11.8 inch. A third field, "item dimensions", lists 28cm instead.
Is it medium or medium-firm?
Both appear. The spec sheet's firmness field says Medium, while the bullet points describe the Suilong as a medium-firm hybrid. The listing does not resolve the difference.
What size bed frame does it fit?
The size field says small double, 120 x 190cm, and the title says 4ft by 6ft3. One other field gives the dimensions as 28 x 200 x 28cm, so measure your frame before ordering.
What is it made of?
Gel memory foam, high density foam, memory foam and pocketed coils, with a 3D breathable fabric cover that Suilong describes as antimicrobial.
Is there a trial period, and how does it arrive?
Suilong offers a 100-night sleep trial. The mattress arrives compressed, vacuum-sealed and boxed, and the care instructions say hand wash only, with the mattress rotated seasonally.
