Firm Mattresses

Firm Mattresses

Firm mattresses are more supportive than others. Designed to be stiffer, preventing the body from sinking in, they can sometimes be referred to as orthopaedic mattresses or 'ortho mattresses'.
Our range of firmer-feeling mattresses is made by some of the top brands such as Hypnos, Sleepeezee, Harrison Spinks and many, many more!
