Experience sleep like never before with the Sealy Posturepedic Elevate Holst Mattress! Featuring Sealy's very own innovative tech for a truly unmatched sleep.

Sealy's unique Posturepedic coil spring support system is specifically designed to perfectly align your spine by sensing and responding to your body weight. The twice tempered springs never lose their responsive nature.

Soft and flexible reflex foam enhances the support needed for excellent spinal alignment. The sumptuous nature doesn't compromise on the cosy comfort either.

Offering a soothing night's rest by evenly distributing your body weight across the mattress. The pressure point relief provides the ultimate relaxation needed for a deep slumber.

Durable edge-to-edge support provides a maximised sleeping surface for a more secure sleep. Sit and lay comfortably right to the very edge with zero 'roll-off' sensation.

Free of allergens for a cleaner, healthier sleep. No allergenic materials were used so you can enjoy an undisturbed rest without the risk of allergy reactions or respiratory problems.

A sumptuously soft finish that provides additional cosiness and warmth. Knitted covers enhance airflow and are incredibly breathable. So, you can enjoy a cooler snooze.
Not too soft, not too firm - the perfect balance

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.

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.

This Mattress was beautiful, well made & perfect in every-way, apart from it being medium firm which is too soft for me!
Verified Purchase
I have found this mattress to be extremely comfortable - I have hip/ knee and back issues and I sleep without pain on this mattress. It feels as if I am being held firmly but gently, it is very well made, a quality mattress, no settling has occurred, I have turned it every couple of weeks, it is not heavy I can turn it on my own. age 81yrs. It is deep and sumptuous worth every penny. I would agree it is medium firmness, you feel held level - that's the posturepedic springing. Recommend without hesitation.
