Sealy Ortho Posture Firm Mattress

Featuring Sealy’s exclusive PostureTech Core Support spring system, this firm mattress works to support your body where you need it the most. The springs gradually get firmer as pressure increases to provide deep down support and pressure relief.

A combination of Purotex and silky soft TENCEL™ fibres are nestled in the fabric of the mattress to reduce moisture and allergens that may cause irritation during the night. Endorsed by Allergy UK, Purotex works to keep your mattress clean, fresh and odour free. Over time, your mattress feels just as good as the day you placed it in your bedroom. The hand-tufted surface provides a luxurious and durable feel – perfect for those who prefer a sturdier, more traditional sleep surface.
