The dosleeps Small Double Mattress is the entry at number six in this guide. It is a 120 x 190 x 27cm hybrid — gel memory foam over a 9-zone pocket sprung unit — listed at £153.69 and rated 4.4 out of 5 from 2,686 ratings.

The finding on this ficha is a missing number rather than a conflicting one. The other listings in this guide quote coil counts running from 7 to 700, and they disagree so widely that the figure is close to useless. The dosleeps listing never gives one at all: it says 9 zones, individually pocketed coils and tempered stainless steel wire, but no total anywhere. What is stated holds together, though. The title's 10.6 inch works out at roughly 27cm, which is exactly what the spec sheet gives for the thickness. The layer count is listed as 12.0, which is a lot of layers to fit into 27cm. Everything on this page is taken from the Amazon listing, not from any testing we have carried out.
