Drawing on over 100 years’ experience and expertise, Sealy has created a mattress that offers all the support you need, with absolutely no compromise on comfort. Simple in design yet complex in construction, it combines modern materials with traditional manufacturing techniques that have been passed down through the generations. The firm rating makes it suitable for those who suffer from back pain, or for those who simply prefer a firmer feel. It’s also a single-sided option making it much lower maintenance than a double-sided mattress.

The mattress looks as good as it feels too, with a silky-soft Damask cover over the top and extra layers of fillings to create a cushioned feel. It is categorised as an orthopaedic mattress, designed to provide firm support right across the whole sleeping area. It is a single-sided mattress so there is no need to flip and turn it, but we do recommend that it is rotated every few months to prolong its lifespan and to prevent fibre compression. Made in the UK, it has a 5-year guarantee for your peace of mind.

Posturepedic Spring System supports all night long

Sealy’s core support system is at the very heart of their mattresses. Using an advanced design that means the springs gradually get firmer as the pressure increases, the spring system helps to keep the spine in a neutral position and minimise pressure points on the hips and shoulders. The result is a better, more restful night’s sleep with less tossing and turning.

Traditional methods for a better finish

The Sealy Support Firm mattress uses a method called hand-tufting. This traditional method of upholstery uses the skill of the artisan to hand-secure the mattress fillings in place so that they don’t move around, which could result in uncomfortable lumps and bumps forming over time. All of the tufts are positioned by hand, running right through the mattress to secure all the loose fillings for the ultimate finish.

Hypo-allergenic for a healthier environment

The presence of dust, mites, and canker can quickly irritate the airways, especially if you suffer from allergies or medical conditions like asthma, COPD or rhinitis. The Sealy Support mattress is a hypo-allergenic option that prevents unwelcome guests like dust mites from taking up residence, ensuring your mattress stays cleaner and is a healthier environment. The Sealy Support Firm mattress is so good at it that it’s been endorsed by Allergy UK.
