Description

The Silentnight Memory Cool 1000 Mirapocket Mattress offers you a cooler, more comfortable sleep environment.

Sink-in comfort

Like traditional memory foam, Memory Cool™ advanced foam gently contours to your body. Taking pressure off your muscles and joints for relaxing comfort. This relief of built up pressure can encourage a more restful sleep night after night.

The indulgent sink-in feel of the foam helps to minimise excessive movement during sleep. This reduces roll together and minimises partner disturbance, helping you sleep undisturbed.

Graphite-infused cooling

Silentnight’s innovative Memory Cool™ foam is infused with graphite particles. They absorb and dissipate body heat. As you sink into the foam, your body weight compresses the material. This forces the graphite particles closer together, so they can conduct heat through the foam and dissipate it quickly. The result is a sleep environment 15% cooler than standard memory foam.

Mirapocket springs

1000 individually pocketed Mirapocket® springs provide zoned support that adapts to your body. As a result, encouraging spinal alignment to ease aches for a truly restful night’s sleep. This zoned spring unit is firmer in the centre third and scientifically proven to support the spine in key areas when compared to a non-zoned unit. So you can enjoy extra support, night after night.

Breathable border

This mattress features a mesh border with a 3D knit structure. The spacer design creates a small gap between the inner layers and the outer fabric of the mattress. So air is able to circulate more freely. This helps release heat and moisture built up while you sleep, keeping your mattress cooler and fresher.

Tried and tested

Silentnight works closely with foam manufacturers to design and test foam. This ensures it reaches their high standards. Memory Cool™ foam is proven to be cooler than standard memory foam, thanks to advanced thermal testing. And with expert 3D movement analysis, the zoned Mirapocket® springs are shown to support the spine more effectively. Especially in key areas like the lower back.

Trusted quality

As one of the first B-Corp certified sleep brands, Silentnight have proven why they are the UK’s most trusted name in sleep. Their commitment to quality and environmentally responsible practices ensures a better night’s rest and a brighter future for you.

Crafted by Silentnight—one of the world’s most trusted mattress brands with a reputation for lasting comfort and support. Backed by a 5 Year Guarantee for added peace of mind.

Please note: pocket spring count is based on a kingsize mattress
