About this product
Add cooling comfort to your bed with this breathable mattress topper that combines innovative foam layers for supportive, restful sleep. The advanced Octaspring technology and aerocell foam create a structure that allows air to circulate freely, keeping things fresh and comfortable while you rest. At 7cm deep, it adds supportive cushioning to your existing mattress without feeling too bulky or overwhelming. The fitted design stays securely in place on your king size bed, so you won't wake up to a bunched-up topper that needs constant adjusting.
The foam filling is non-allergenic, making it suitable for sensitive sleepers who need extra reassurance. The cover wipes clean easily, keeping maintenance simple and practical for everyday use.

Customers Say
Comfortable and supportive mattress topper improves sleep and reduces aches, but many users report it slips on the mattress due to lack of securing straps, and some find it too soft or warm.

Extremely comfortable
Really comfortable i am disabled with a spinal injury, and the topper was great for support. Gave 4 stars as the cooling did not work, found the topper hot to sleep on with a cover

Topper is comfy but moves.
Very comfy Topper but it moves on top of the mattress when slept on. Its king size and I have 2 fitted undersheets and a fitted sheet it on. Over a few nights it creeps upward and sideways. So that there is a 25cm gap at tje bottom and it ruckles up towards the top . It needs corner straps to anchor to the mattress.
