A premium quality mattress by a name you can trust, the Sealy Pearl Memory Mattress combines their unique PostureTech Core Support Spring system and Memory Foam originally designed by NASA. That means you have a next-level mattress with a perfect combination of support and comfort. It’s hypoallergenic too, so ideal for those who suffer from allergies or respiratory conditions such as asthma that’s triggered by dust or mites.

Medium to firm support – for those suffering from back problems

Getting comfortable in bed when you have a bad back can be a nightmare. The Sealy Pearl Memory Mattress eliminates that problem by providing you with a medium to firm support level. The memory foam cradles your body, eliminating pressure points and helping you settle down to an uninterrupted night’s sleep, while the PostureTech Core Spring system spreads the weight and reacts to your body, providing more support where it’s needed most.

Made in the UK by a trusted name

Sealy have been making mattresses for over 100 years and are one of the UK’s most trusted names when it comes to that all-important mattress for your bed. The mattress is approved by the National Bed Federation, and comes with a 5-year manufacturer’s warranty for total peace of mind.

Allergy UK Seal of Approval

Dust and mites can be very dangerous to those who suffer from severe respiratory conditions such as COPD or asthma, and if you have allergies then they can also trigger a very unpleasant reaction. The Sealy Pearl Memory Mattress is hypoallergenic, so there’s nowhere for those pesky mites to hide! It’s good enough to get the Seal of Approval from Allergy UK, too.

The Sealy Pearl Memory Mattress is 25cm deep, so you get plenty of mattress for your money! The Tencel cover is made from sustainable fibres, so this mattress is a greener option too. It’s single-sided so you don’t need to flip and turn, although we do recommend that you turn it from top to toe every few months for maximum comfort. The turning handles on the sides make this quick and easy.


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.

Memory Foam

Originally designed by NASA, Memory Foam moulds to your body, giving orthopaedic support and superb comfort. It also helps to overcome the pressure points of the body.

Reflex Foam

Used together with springs, or as the support layer in all-foam mattresses, Relfex Foam is versatile and comfortably supportive.

25cm Depth

This mattress is approximately 25cm deep.

Medium Firm Support

Good for people who change sleeping position.

Tencel Cover

The mattress cover incorporates Tencel, an innovative fibre that naturally cools you and manages moisture. Tencel also helps to combat bacterial growth and is soft and comforting.

Allergy UK Seal of Approval

This mattress is protected from any unwanted allergens and has the Allergy UK Seal of Approval.

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.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.


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

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.
