Rank #6 in Best Cheap Mattress 2026: What Fifty Pounds Actually Buys
eXtreme comfort ltd Diamond Essential Grey Single Mattress, Foam Free, 18cm
Price and rating as shown on Amazon when we collected them. Both change.
The eXtreme comfort Diamond single mattress costs £56.95 and is rated 4.1 stars from 520 ratings, with a Bonnell open coil spring unit and an eighteen centimetre depth.
It takes sixth because it is the only mattress here sold on what it does not contain — foam — with a named spring type instead, and an 80 kilogram limit that makes it a mattress for one ordinary adult.
How those 520 ratings break down
An average hides its own shape. This is the spread behind the 4.1 stars.
