Price and rating as shown on Amazon when we collected them. Both change.
The dosleeps 4FT Small Double is a hybrid mattress measuring 120 x 190cm, built from gel memory foam over a 9-zone pocket spring unit and sold at £139.99. It takes third place in this guide. The interesting part is what the listing does and does not put a number on: the spec sheet logs 550 pocketed coils, while the marketing bullets describe the 9-zone spring system without ever stating a coil count. So 550 is the only coil figure this listing itself gives, even though dosleeps is quoted at 700 coils elsewhere in this guide for the same 120 x 190cm footprint.
The thickness moves around too. The title says 10 inches, the dimensions say 190 x 120 x 25cm, and the same listing carries a separate Item Depth of 24cm — three figures for one measurement. The 4.4 rating comes from 3,524 ratings, and the reviews shown on this page include a buyer describing a single 90 x 190cm mattress and another describing a king size, so that average covers more than the 4FT small double. Everything below is taken from the Amazon listing; we have not tested this mattress.
