About this product
Keep your sleep comfortable and undisturbed with this mattress topper designed to prevent overheating. Its breathable outer fabric allows air flow, while moisture-wicking properties draw perspiration away to keep you fresh. The memory foam core absorbs body heat and releases it through channels for better temperature control without waking you hot. The 8cm depth adds supportive comfort to your existing mattress and fits king size beds, providing full body support that helps rejuvenate tired mattresses.
The removable cover is machine washable at 40C and tumble dryer safe, so keeping it clean is straightforward and convenient. The 8cm depth gives meaningful support without replacing your whole mattress, which makes it a practical upgrade. Whether you're a naturally warm sleeper or you want to refresh your current setup, this topper delivers breathable comfort and better sleep quality that works night after night.

Customers Say
This mattress topper offers comfort, support, and improved sleep for many users, with elastic corner straps securing it well. However, some find it firm, bulky, or lacking cooling effect, and a few report missing straps or unpleasant odors.

Disappointing
I let this sir outside all day, so no chemical smells. It’s not as soft as I hoped it would be. My hip still aches by morning. Doesn’t really feel like memory foam. Very disappointing for an expensive mattress topper.

Would not recommend
I bought this to help me keep cool in bed. Though fairly comfortable, and keeping me cooler to begin with, it soon warmed up and made little difference after a few minutes. Also: I bought the size for a king size bed, it came in a large and quite heavy box - the picture of the product suggests something you can easily care by a carrying handle - misleading.
