The Silentnight Memory Cool 3000 Box Top Mattress combines graphite-infused Memory Cool™ foam with 2,000 Mirapocket® springs and 1,000 mini springs. Its generous box-top design adds cushioning comfort, while the cooling foam helps manage body heat for a more refreshing night’s sleep.
3,000 Springs for Responsive Support
This mattress features 2,000 Mirapocket® pocket springs and 1,000 mini springs, working together to provide responsive support and a comfortable sleeping surface. The pocket springs respond independently to your body, helping distribute weight evenly, support spinal alignment and minimise movement transfer between sleeping partners.
Memory Cool™ Foam for a Cooler Sleep
The graphite-infused Memory Cool™ foam gently contours to your body, helping relieve pressure on muscles and joints. Its graphite particles are designed to absorb and dissipate body heat, helping create a cooler sleeping environment than standard memory foam.
Box-Top Comfort
The box-top design gives the mattress a deeper, more cushioned feel. Combined with contouring memory foam and responsive spring support, it offers a comfortable surface for those who prefer a softer, more enveloping sleeping experience.
Soft / Medium Comfort
The manufacturer describes the mattress as medium soft, offering a little more give than a medium mattress. This makes it an option for sleepers who prefer softer cushioning while still wanting the support of a pocket spring system.
