If you're looking for a mattress that prioritises stability, posture support, and long-term durability, the Sealy Burlington Backcare Extra Firm Mattress delivers a confidently supportive sleep experience. Crafted in the UK exclusively for Bensons for Beds, this backcare mattress is designed for sleepers who value a firmer feel without compromising on breathability or comfort.The mattress features Sealy's PostureTech Core Support spring system, which adapts to your body as you sleep. As pressure builds, the springs respond by becoming progressively firmer, helping to maintain even weight distribution and support the spine in a neutral, aligned position throughout the night.Wrapped in a Belgian damask cover, the surface feels smooth and breathable while standing up to everyday use. Beneath this, ReNew fibres — made from 76% recycled PET plastics — promote airflow through the mattress, helping heat to dissipate for a cooler, fresher sleep while offering impressive durability.To ensure strength from edge to edge, EdgeGuard technology reinforces the mattress perimeter, reducing the feeling of roll-off and increasing the usable sleeping area. The mattress is hand-tufted to keep the internal layers securely in place, delivering a firm, consistent feel over time.Designed for ease as well as support, the Burlington Backcare Extra Firm is an easy-care, non-turn mattress that only requires regular rotation in line with the care guide. With a 27cm depth, an extra firm comfort rating, and a free 5-year guarantee* for added reassurance, it's a practical and dependable choice for supportive, no-nonsense sleep.Also available in a firm comfort option as the Sealy Burlington Backcare Firm Support Mattress.*T&Cs apply.
