The Sleep Retreat collection offers total comfort solutions across a range, so there is a mattress for everyone. The perfect solution if you love a refreshing night's sleep. That's because the breathable fibres work to keep you cool and comfortable all night long. Made in the UK by Silentnight, exclusive to John Lewis. Comfort Fibre Layer This mattress features a Comfort Fibre Layer, made with fibres which provide incredible comfort and are extra breathable - perfect if you get hot during the night. This comfort layer contains 22.4% recycled content. These recycled fibres are traceable through a GRS (Global Recycling Standard) audited supply chain. The mattress cover has a soft to the touch quilted finish that's not removable. Rotate the mattress regularly. Mirapocket® springs Individual Mirapocket® springs offer zoned support for improved spinal alignment. Each spring responds and reacts to your movement and acts independently, so when you move throughout the night your partner won't feel a thing, meaning you'll both enjoy a more restful night's sleep. Extend the life of your new mattress with a durable and breathable mattress protector. To take part in the Silentnight 60 Night Comfort Trial, you must agree to use a mattress protector of the correct size, purchased in the same transaction.
