Rank #4 in Best Small Double Mattress 2026: 10 Ranked, Coil Counts Compared
dosleeps 9-Zone Small Double Mattress, 22cm
Price and rating as shown on Amazon when we collected them. Both change.
The dosleeps Small Double Mattress is the fourth entry in this guide to small double mattresses. It is a 4ft mattress measuring 120 x 190cm and 22cm deep, sold at £139.99 and rated 4.5 out of 5 from 784 ratings on Amazon. The listing describes a hybrid build: gel memory foam over a 9-zone pocket spring unit, wrapped in a polyester cover with 3D breathable mesh on the side, and a medium firm feel.
What stands out in this ficha is the coil count. dosleeps claims 700 pocket springs inside the same 120 x 190cm footprint in which other listings in this guide log 7 coils (Twirest, for a 7-zone unit), 90 (Doublelife, 9-zone) and 150 (BEDZONLINE, Bonnell). 700 springs over 9 zones works out at roughly 78 springs per zone — arithmetically plausible on its own terms, and impossible to check from the page. The thickness figure does not hold as neatly: the product name and the spec sheet both say 9 Inch / 22cm, while a five-star review on the same listing describes a "Thick 27cm design". Everything on this page is taken from the Amazon listing, not from any test of our own.

Verified purchase“What I like 👍Thick 27cm design gives it a substantial feel.Memory foam + pocket springs offers a combination of cushioning and support.Motion isolation is a useful feature if the bed is shared. Vacuum-packed delivery makes it easier to move upstairs and set up.Is it worth buying? Yes, if you want a reasonably priced, thicker mattress for a single bed. The combination of memory foam and pocket springs makes it appealing for everyday sleeping or a guest room.”
