Product Information.
Introducing the Geltex® 4000 Pocket Boxtop Mattress from Silentnight. A gel-infused comfort layer that actively responds to your body as you sleep, allowing you to toss and turn without sleep disturbance. Perfect for twisters and turners.
Featuring Silentnight's exclusive Geltex® layer which actively responds to your body as you sleep, for easy movement and 'bounce-back' to help you feel energised, every morning with more ‘get up and go'. The gel infused comfort layer distributes body weight and pressure evenly, for soothing pressure relief. Geltex® is also incredibly breathable compared to memory foam, so it allows for a more refreshing and cooler night's sleep.
The Geltex 4000 Pocket Boxtop combines two layers of 1000 Ultraflex mini-springs for enhanced comfort and personalised support, alongside Silentnight's exclusive Mirapocket® spring system. A double layer of 2000 individual pocket springs and additional 2000 mini-springs respond independently to weight and deliver tailored support where you need it most. The 2000 mini-springs and the Geltex layers are combined in a deep boxtop for the ultimate deluxe mattress, which is hand tufted for a slightly firmer feel.
