Price and rating as shown on Amazon when we collected them. Both change.
The dosleeps king size mattress costs £159.99 and is rated 4.5 stars from 782 ratings, with nine zones of pocket springs, gel memory foam and a twenty-two centimetre depth.
It takes third because its 782 ratings are the same 782 that the dosleeps single carries in this site's cheap mattress ranking — one pool, two sizes, two articles — and because its name rounds twenty-two centimetres up to nine inches, as its sibling does.
How those 782 ratings break down
An average hides its own shape. This is the spread behind the 4.5 stars.
