What the Sleep Expert thinks...

"This mattress has excellent cooling properties, but also provides impressive back support for those looking to relieve aches and pains. I'd recommend this mattress to anyone needing a firmer feel plus a cooling sensation."

Description

Sleep with full-on support thanks to the Silentnight UltraGel™ 1000 Pocket Mattress, designed with intelligent comfort technology to help you move freely and sleep deeply. With an orthopaedic medium firm feel, this mattress features reactive Mirapocket® springs to provide impressive full-body pressure relief.

Orthopaedic support and pressure relief

Individually nested, these Mirapocket® springs are able to adapt quickly to your movements, ensuring every one of your pressure points is met with the precise level of support it needs. This clever technology means that your spine is encouraged to stay in proper alignment, giving you a healthier sleeping posture and reducing the chances of aches and pains when you wake up!

Cooling comfort all night long

What sets this mattress apart, however, is the UltraGel™ premium comfort layer. Infused with cooling gel, this layer draws heat away from your body, reducing overheating and creating a truly refreshing sleeping environment. It also moulds to your body shape, providing cooling comfort at every point of contact and further relieving tension across your whole body.

Enhanced durability for peace of mind

Between this innovative cooling layer and the spring support unit are layers of stabilising and protective materials that enhance the durability of your mattress. Meticulously crafted by one of the world's most famous sleep brands, this Silentnight mattress cuts no corners when it comes to expert craftsmanship.

The perfect upgrade to any bedroom!

Finished with a plush quilted sleep surface, this mattress adds a sense of luxury to your bedroom. At 28cm deep, it sits pride of place on any bed frame, and is available in a range of sizes so you can easily upgrade your room, your child's room, or your spare room as you wish!

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.

Turning Handles

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