Description

Choose comforting luxury with the Silentnight Memory Cool 3000 Mirapocket Box Top Mattress. Enjoy the sumptuous box top surface with supportive zoned springs and refreshing graphite infused foam.

Box top indulgence

Sink into sumptuous comfort with the Memory Cool™ 3000 mattress. It's expertly designed for responsive support and body-contouring relief. The mattress features a distinctive box-shaped profile. This is similar to a pillow top with enhanced structure and durability. This design feature contains all the comfort elements. And gives your mattress a more luxurious look and feel.

Cool embrace

Enjoy the refreshing feel of Cool Memory™ foam. Silentnight’s in-house testing showed Memory Cool™ foam to be 15% cooler than standard memory foam. It gently embraces your body, taking the pressure off your muscles and joints. All the while, keeping you comfortably cooler. Graphite infused particles within the foam absorb and dissipate body heat. Resulting in a cooler, more restful night’s sleep.

Zoned springs

This mattress features a unique zoned spring system. At its core it has 2000 responsive Mirapocket® springs. These individually adjust to your body weight and movement to keep you supported as you sleep. This spring unit is zoned in the centre third which means it provides firmer support to your shoulders, and hips. Helping to encourage spinal alignment and reduce aches and pains. Providing tailored support exactly where you need it most.

Mini springs

The Mirapocket® springs are paired with 1000 mini springs that add extra comfort. Acting like tiny bellows, they help circulate air through the mattress, improving breathability and keeping you cooler as you sleep.

Tried and tested

Silentnight rigorously tests every mattress to ensure lasting comfort and performance. In-house pressure mapping analysis shows their memory foam helps relieve pressure build-up. While airflow tests revealed that mini springs effectively push air through the comfort layers enhancing breathability.

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.

Silentnight has a reputation as one of the world’s most trusted mattress brands. They are known for expert craftsmanship and long-lasting comfort. So you can be assured you’re purchasing true quality backed by a 5 Year Guarantee.

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