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 two firm compressed support pads in the comfort layers to give the mattress an overall extra firm feel. This makes it the ideal mattress for someone who wants to maximise their back & hip support. The mattress is no turn for easy care.
