Is This the Best Orthopaedic Mattress for Back Pain?
The Sealy Mellbreak Ortho Plus is purpose-built for back care. The PostureTech spring system offers zoned support, helping to align your spine and reduce pressure on the lower back. This is especially beneficial for those experiencing stiffness or pain in the morning.
The firm tension is ideal for back and stomach sleepers, delivering the kind of surface that promotes proper posture without sinking or sagging. Unlike softer or foam-based mattresses, the Mellbreak is also cooler and more breathable.
If you’re searching for one of the best orthopaedic mattresses in the UK, this should be high on your shortlist.

If you’re comparing firm orthopaedic mattresses, the Sealy Mellbreak Ortho Plus stands out for its superior edge support, breathable design, and consistent spinal alignment. The Sleepeezee Backcare Deluxe 1000 offers good value but lacks reinforcement, while the Silentnight Miracoil Ortho suits tight budgets but sacrifices long-term comfort.
👉 For a firmer feel without compromise, the Mellbreak remains a top pick.
