About
The Viscount King Size Mattress is a high quality memory foam mattress that has been developed by NASA to create one of our most comfortable mattresses. The high quality foam moulds to your body shape as it reacts to your body temperature creating the most comfortable, tailor made night’s sleep you’ve ever had. Coolmax technology has been developed into the mattress that allows air to flow through the fabric that keeps you cool during the summer months and warm through those chilly winter evenings.
