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.
