The Infinity springs system for mattresses is the most advanced “continuous coil” support system in the UK. There are over 900 springs in a (5’) Infinity mattress & they are joined from head to toe, so not only does it give an unrivalled level of support, but it also prevents roll-together of two people on the mattress. This Infinity mattress has been upholstered in a fabric with Nano Silver Technology. It has microscopic silver particles woven into it which remove the static charge from your body. This has been scientifically proven to make you sleep deeper for longer, therefore making you feel more refreshed. Please see the “ Silver Safe Revolution” tab above for more details This mattress also has a layer of visco elastic memory foam. This has been shown to reduce pressure points between the mattress & your body, thus reducing aches & pains & also reducing tossing & turning during the night.
