Rank #7 in Best Mattress for Side Sleepers 2026: Two Say Extra Firm
Hybrid Double Mattress Extra Firm 4ft6, 25cm, 29kg
Price and rating as shown on Amazon when we collected them. Both change.
This extra firm hybrid double costs £149.99 and is rated 4.3 stars from 418 ratings, with a twenty-five centimetre profile and a twenty-nine kilogram body.
It takes seventh because it is one of only two mattresses here that say extra firm — while its thickness field reads zero point two five centimetres, which is a metric conversion that changed the unit and left the number behind.
How those 418 ratings break down
An average hides its own shape. This is the spread behind the 4.3 stars.
