The Pure Relief Memory Foam mattress contains a supportive 18.5cm layer of eco-friendly reflex foam topped with memory foam allowing the body to sink into the mattress slightly relieving pressure on bones, joints and muscles whilst maximising life span. The cool blue memory foam has a 60kg density making it durable and long-lasting. Cool blue memory foam offers all of the comfort and orthopaedic qualities of standard memory foam but it dissipates heat up to 5 times quicker than standard memory foam, for a cooler, fresher sleep. The zoned mattress is designed to support the body where it needs it most ensuring peaceful, undisturbed sleep night after night.
