Description

The Coolmax double mattress from Kayflex combines a deep 50mm layer of hypo-allergenic memory foam and a Coolmax cover for a fresher and healthier night's sleep.

Perspiration is one of the body’s natural mechanisms and Coolmax is designed to draw body moisture, helping you stay dry and comfortable.

Coolmax is an innovative fabric that dissipates perspiration away from the body and through the fabric, where it can evaporate quickly.

Its specially engineered fibres produce fabrics that are soft to touch, breathable and helps to keep you cool in the summer and warm in the winter. 

The deep memory foam layer is temperature sensitive, designed to soften when it comes into contact with warm surfaces and moulds itself to the sleeper’s body shape.

This reduces the pressure points on your body, creating better blood circulation and results in less tossing and turning by evenly distributing your body weight. Supporting the memory foam is a 150mm of reflex foam that creates a solid foundation and offers additional support.

Designed to be one-sided, the mattress does not require to be flipped over, but does need to be rotated from head to toe. It is delivered vacuum packed in a roll; ideal where access is limited and perfect for converted loft rooms.

The Kayflex Coolmax mattress is perfect if you are looking for a non-sprung mattress that's not too hard and not too soft.
