Description

Delve deep into sleep with the Sealy Posturepedic Elevate Holst Mattress. Designed with a medium feel, the perfect blend between soft and firm!

Part of the Posturepedic collection, this mattress provides the support you've been looking for!

The Sealy spring

The core of this mattress features Sealy's innovative AlignSupport™ springs. Built to respond to your weight, the springs provide support to different parts of your body. They align your spine, allowing your muscles to relax so you can fall into a deep, restorative sleep! The spring unit is twice tempered too, providing dependable performance year after year.

Sturdy edge

All Sealy Posturepedic mattresses have special UniCased® technology which stabilises the mattress and secures the fillings in place. This smart technology provides strong edge support, enhancing the durability of the edge. So, you are able to sit on the edge of the mattress without the sides collapsing. The UniCased® system also removes the 'roll-off' feeling when you're falling asleep.

Cosy fillings

This mattress features ComfortCore™ to target your lower back for ultimate support and blissful pressure relief.

Followed by Sealy's unique InfiniLux™ foam, a luxurious foam that provides long-lasting comfort. This mattress has a medium feel, the perfect middle ground from being too hard or too soft.

If you are wanting a mattress that is a little firmer, check out the Sealy Blackwood Elevate Posturepedic Mattress!

Breathe easy

Wrapped in a chic quilted cover, you can breathe easy at night. The cover has been treated with ProShield® fibres protecting you against any allergens. Don't just have to take our word for it, ProShield® is proudly endorsed by Allergy UK.

The SmarTex™ cover treatment wicks away any moisture and regulates your temperature. The innovative treatment allows you to get a cool, fresh sleep at night!
