"Just Calm is designed to help you sleep in cool comfort"

Improve your sleep quality, metabolism and improve blood circulation with improved air circulation for a cooler, fresher sleep. 1000 pocket springs adjust to your body for edge-to-edge zoned support and enhanced spinal alignment. Finished with a soft-knit fabric which is hypoallergenic and comes rolled and boxed for convenience and easy delivery up staircases. Non-removable cover.

Stimulates your metabolism and helps to improve blood circulation for all-round improved sleep and well-being. This is possible because the Vitalize sleep surface absorbs body heat and reflects this lost energy back into your body. The technology has been tested to the highest standards and doesn't contain any chemicals.
