Sumptuous softness meets essential support in the Silentnight Memory Cool 3000 Pocket Box Top Mattress, designed and crafted by the most trusted sleep brand in the UK. 37cm deep, this high-profile mattress is full to the brim of innovative sleep technology to keep you blissfully comforted and supported all night long.

Innovative Mirapocket® springs provide essential posture control

For full-body support, a dual layer of Silentnight's famous Mirapocket® springs - plus an additional layer of mini springs - provides essential pressure relief. Maintaining the soft feel of the mattress, these springs ensure you still enjoy that sink-in feeling, but keep your posture aligned to help reduce back pain and aches.

Sink-in soft comfort feels like you're lying on a cloud

For indulgent comfort, a double layer of foam and specialist Memory Cool™ foam moulds to your unique body shape. Relieving tension at every point of contact, these foam layers ensure consistent cushioning exactly where you need it - even applying pressure relief to your wrists and ankles! The Memory Cool™ technology is 15% cooler than standard memory foam, drawing heat away from your body to prevent overheating and maintain a cooler sleeping environment.

Cooling technology prevents overheating and keeps things fresh

Between the layers of springs and comfort foam are stabilising foam layers, created to enhance the durability of the Silentnight Memory Cool 3000 Pocket Box Top Mattress. A protective layer at the very bottom of the mattress also ensures the clever springs inside are kept safe, allowing them to provide targeted pressure relief as effectively as possible.

Soft to the touch and crafted with meticulous care

Finished with a box top sleep surface design, this mattress has a breathable mesh border to allow for maximum air circulation, creating a fresher, more hygienic sleeping environment. Soft to the touch, a quilted cover adds a final touch of luxury, letting this soft Silentnight mattress become a definite favourite for anyone who spends the night on it.

Available in a range of sizes from single right through to super king, the Silentnight Memory Cool 3000 Pocket Box Top Mattress can sit pride of place on any bed frame. Whether you want to upgrade you master bedroom or treat your guests to a luxurious night's sleep in your spare room, this mattress is sure to impress.
