Featuring Silentnight?s exclusive Mirapocket zoned spring system, this Tranquillity 1000 Pocket Memory mattress is scientifically proven to provide better spinal alignment for healthier sleep and improved posture to ease any aches and pains. With 1000 individually responsive springs which contour to your body shape, it?s designed to offer tailored comfort and pressure relief second to none. A deep layer of memory foam in this mattress offers ultimate pressure relief with soothing, cocooning comfort to create a truly relaxing sleep each night. And, although memory foam often encourages a hot environment, the breathable border on this mattress helps to allow airflow for a cooler sleep compared to a standard memory mattress. A traditional hand tufted finish offers a slightly firmer feel and outstanding durability. As a single sided mattress, there?s no need to turn it, simply rotate for longevity. This mattress is hypoallergenic, so it?s designed to reduce the chance of an allergic reaction so you can sleep without worry in a relaxing environment. Mattress firmness: Medium/Firm. Made in the UK. Full 5-year manufacturer's peace of mind guarantee.
