Hypnos Denhome Luxury Comfort Emperor Mattress

Cover
A blend of cotton, viscose and damask fibres with a chemical-free fire retardant treatment, which means it meets fire safety standards while staying kind to your skin. It's a soft, traditional-feeling surface rather than a synthetic one.

Comfort layer
Solotex padding made from recycled plastic sits just beneath the cover. It creates the cushioned initial feel you notice when you first lie down.

Wool filling
British wool, certified to the Responsible Wool Standard, acts as a natural insulator. Its breathable structure adjusts to your body temperature, so you're less likely to wake up too hot or too cold.

Cotton filling
Natural cotton fibres wick away moisture and help regulate temperature through the night. If you're a hot sleeper, this layer works alongside the wool to keep things fresh.

Support system
A core of 1200 ReActivePro six-turn pocket springs responds to each part of your body independently, which means your partner's movements are less likely to disturb you. Three rows of extra durable springs around the border firm up the edges.
