Kaymed have over a century’s expertise at the forefront of sleep technology and are the leading innovator in the gel and visco-elastic technologies.

The Thermaphase+ Harmonise 2500 from Kaymed, has 2500 (based on a King Size) Pocket springs along with a layer of ThermaPhase+ visco elastic material and a copper infusion.

Thermaphase+ is a pressure relieving high density material and contains unique phase-change crystals and copper particles. The phase-change crystals work by absorbing and releasing body heat constantly, this helps to maintain an ideal surface temperature to sleep in. The copper infusion works as a super-fast conductor, moving heat to and from the mattress surface.

Copper is also naturally anti-bacterial and anti-viral. Working with the pocket springs, Thermaphase+ is designed to respond immediately to any body movements, giving optimum support and comfort which is essential for a restful night’s sleep.
