The Sealy Support Firm mattress is part of Sealy's Essential range, offering great levels of comfort and orthopaedic support, without breaking your pocket.
The Sealy Support Firm mattress is built using Sealy's Zero deflection triple offset spring system, meaning the mattress can soak up motion and body weight effectively, whilst carefully aligning to the contours of your sleeping form. It uses a heavy-gauge metal rod around the edge of the mattress to keep everything firm and stable, allowing the Support Firm to live up to its name effectively, as a comfortable supportive mattress with a firm feel.
The Support Firm mattress is an easy-care, no-turn mattress with a luxury damask cover and a traditional tufted finish.

The edge to edge support for me is brilliant and the firm rating spot on for my needs especially if you've back issues. Being disabled I need the mattress to support me at the edge and not sag which many do so I love it thank you for your help and support
