PostureTech Zero Deflection Spring System that’s unique to Sealy

Sealy’s PostureTech spring system has been specially developed by this manufacturer to provide you with a better night’s sleep. The Zero Deflection Spring System minimises movement to almost zero, giving you a much firmer feel and no roll-together. It’s ideal if you’re larger or suffer from a bad back, or simply prefer the feel of a really firm mattress!

Tencel cover keeps you fresh and dry all night long

On hot summer nights, things can get a bit sweaty! Sealy uses Tencel fabric to cover the Sealy Pearl Ortho Mattress, which wicks away moisture so you stay dry and fresh all night long. If you’re interested in saving the planet then Tencel ticks that box too, as it’s sourced from sustainable fibres.

Reinforced edges prevents mattress ‘side-sagging’

Sealy’s Edge Guard design incorporates a more stable base and stronger stitching on the sides to prevent mattress ‘side-sagging’. You get a larger sleeping area from edge-to-edge, and your mattress doesn’t sag or bulge over time.

The Sealy Pearl Ortho Mattress is a double-sided mattress, so you can flip and turn it regularly (every 4-6 months or so) to prolong its lifespan. To make this easier, the mattress has strong turning handles stitched to both sides, so flipping is a quick and easy job. It’s an NBF-approved product and made here in the UK. The pressure-relieving nature of the design means you don’t end up with pressure points along the back, shoulders, and hips, no matter which position you choose to sleep in or how much you wriggle during the night!


PostureTech Zero Deflection Springs

Sealy's PostureTech Zero Deflection spring system combats both weight and movement to avoid motion disruption during your sleep. It also helps to ensure stable and firm support across the entire sleep area.

29cm Depth

This mattress is approximately 29cm deep.

Firm Support

Good for people who sleep on their front or back.

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.

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.

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.


The mattress has fillings on both sides. Double-sided mattresses need to be turned regularly to keep them in good condition.

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.
