Who is it for? The best choice if you suffer from back pain, prefer to sleep on your back or stomach, or simply need a firmer mattress that holds its shape under pressure. At firm tension (9/10), it delivers corrective orthopaedic support and is rated for sleepers up to 20 stone. It is also the right upgrade if your current mattress has started to sag. What makes it different? Most hybrid mattresses use a single layer of pocket springs. The 4000 Ortho Elite uses a dual-layer system, doubling the spring count and significantly increasing the stability and longevity of the support core. The stability-focused memory foam above the springs minimises sink, keeping your hips and shoulders from dropping out of alignment as you sleep.

Frequently asked questions Is the 4000 Ortho Elite firm enough for someone who wants an extra firm mattress?+ Yes. At a firm 9/10 orthopaedic tension it is one of the firmest mattresses in the REM-Fit range, with 4000 dual-layer pocket springs and stability-focused memory foam that give a solid, supportive feel with minimal sink. It suits shoppers looking for an extra firm hybrid mattress that holds its shape, and is rated for sleepers up to 20 stone. Is an orthopaedic mattress good for back pain?+ For many people, yes. An orthopaedic mattress like the 4000 Ortho Elite is designed to keep your spine correctly aligned and stop your hips and shoulders sinking out of position, a common cause of morning back pain. In our own customer data, 84.5% of firm-mattress shoppers came to us with back pain as their main concern. What is the difference between an orthopaedic hybrid and a standard hybrid mattress?+ Most hybrid mattresses use a single layer of pocket springs. The 4000 Ortho Elite uses a dual-layer system that doubles the spring count for firmer, more stable support, with stability-focused memory foam on top to minimise sink. The result is a firmer, more corrective feel aimed at back support, rather than the medium feel of a standard hybrid. Is a firm mattress better for your back?+ It depends on how you sleep. Back and stomach sleepers, and anyone whose current mattress has started to sag, usually benefit from a firmer mattress that holds its shape and keeps the spine level. Side sleepers who need more give at the hips and shoulders may prefer a medium feel. The 4000 Ortho Elite's 9/10 firm tension is built for those who need corrective, supportive firmness. What size and weight is the 4000 Ortho Elite suitable for?+ It is available from single up to super king, and its dual-layer orthopaedic springs are rated to support sleepers up to 20 stone without losing shape or edge support.
