The Sealy Aspen mattress is specifically designed to provide maximum support for those suffering from back or who prefer the firmness of an orthopaedic mattress. However, there’s no compromise on comfort, and the Sealy Aspen mattress has a luxurious damask covering and a generously deep filling to provide you with that snuggly sensation for a great night’s sleep.

PostureTech Core Support Spring System

This unique system has been developed by Sealy to minimise pressure points and maximise comfort. The spring matrix creates a softer feel that gradually gets firmer as the pressure increases, eliminating those typical pressure points along the back, hips, and shoulders.

Recommended and approved by the NBF

The Aspen mattress by Sealy has been tested and checked thoroughly to ensure it provides exceptional support for those looking for an orthopaedic mattress. Sealy are members of the National Bed Federation. Every NBF Approved Member Manufacturer has undergone rigorous independent auditing to certify that they comply with UK regulations on safety, cleanliness of fillings and trade descriptions, so you can buy with confidence.

Luxurious damask cover and hand tufted finish

Style is never compromised for comfort, and the Aspen looks as good as it feels. A silky-soft damask cover is breathable and easy to care for, while the hand tufting finish ensures the filling is secured for even greater comfort. The overall depth of the mattress is a generous 24cm, ensuring a sound and restful night’s sleep.

Made in the UK, the Aspen mattress by Sealy comes with a 5-year guarantee for complete peace of mind. Available in a variety of sizes, it comes from a brand that’s been trusted to make superior quality mattresses for over 100 years. Because it’s a single-sided design there is no need to flip the mattress, although we do recommend that it is rotate head-to-toe occasionally to prolong the lifespan.


PostureTech CS Springs

Sealy's unique PostureTech Core Support spring system is designed to respond to the heaviest parts of your body and apply the maximum support you need for a great night’s sleep.

Soft White Fibres

Soft white fibre fillings which are made from 100% polyester. This type of mattress filling offers great recovery and is very durable, which means long-lasting comfort.

24cm Depth

This mattress is approximately 24cm deep.

Firm Support

Good for people who sleep on their front or back.

Damask Cover

A mattress cover which is made from a breathable woven damask fabric.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.


Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

Hand Tufted

Tufts help to secure the luxury fillings in place, helping the mattress retain it's fullness and plumpness over time.

NBF Approved Product

Peace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation's Code of Practice.

Made in the UK

This item has been manufactured in the UK.
