Description

Brimming with special sleep technology, the Sealy Posturepedic Elevate Ultra Arden Memory Mattress is part of the Posturepedic collection, this mattress brings you a fine blend of comfort and support.

Perfect alignment

Sealy's very own AlignSupport® spring system offers blissful spinal alignment by sensing and responding to your body weight. This targeted support lulls you into a deeper sleep, letting you get the rest you've been dreaming of.

These clever springs are engineered for longevity. Having been twice tempered at a precise heat, the springs are kept compressed for a whole week to solidify the memory of the springs full height. These springs will keep their responsive nature, extending the lifespan of your mattress.

This mattress has been developed with the Orthopaedic Advisory Board based on scientific research, allowing you to get the best sleep possible without compromising on the support!

Locked in support

All around the edge of the mattress is Sealy's unique UniCased® XT technology. This mattress is designed to provide you with strong edge support. The tailored keys are placed around the spring system to lock it in place and create greater stability, reducing the 'roll-off' feeling and increasing the sleeping surface! The coil inspired air channels also offer greater breathability.

Sumptuously cosy

This mattress is made up of multiple layers of soothing, plush foam. A cosy layer of MemorySense® ComfortCore™ technology provides extra support around the curve of your back for blissful relief to your back and hips.

The layers of memory foam are nestled under a luxurious layer of InfiniLux™ foam. This premium high density foam offers long-lasting comfort all night long! This layer sits in the top of the mattress to cushion your body whilst providing responsive support. Perfect for a deep, restful sleep! This foam is durable to increase the lifespan of your mattress.

A cleaner sleep

Finished in a stylish knit cover, it has been infused with smart fabric treatments. The SmarTex® fibres draw heat and moisture away whilst regulating your body temperature.

The ProShield® treatment fights against allergens for a fresh and clean sleeping environment. This treatment is proudly endorsed by Allergy UK.

The breathable air mesh border allows air to circulate through the mattress with ease. Keeping the mattress dryer and fresher internally.

Environment first

Sealy knows how important sustainability is and that is why this mattress is 100% recyclable at the end of its life. You won't have to worry that this mattress ends up in landfill! The Arden Elevate Ultra also comes with a 7 Year Guarantee.
