The firmer of our two cooling mattresses. Where the Cool Gel puts more foam into cushioning, this one puts more into support - a deeper reflex base with a thinner comfort layer above it, so you stay closer to level rather than settling in. That comfort layer pairs advanced 4G memory foam with a Cool Marble layer, which spreads airflow evenly across the surface instead of letting heat pool where you lie. It also absorbs rebound, so a partner turning over is less likely to move you with them. The foam is CertiPUR certified, meaning it is independently tested and free from heavy metals and dyes. Both the materials and the mattress itself are made here in Britain, in a state-of-the-art facility in the heart of Yorkshire, and the whole mattress is tested to UK fire safety regulations. The soft knit cover unzips completely and machine washes.
