About this product
Keep cool and supported with this breathable mattress topper that sits securely on your super king bed. It's 7cm deep with a fitted design that grips your mattress without shifting around, so you'll wake up with everything still in place. The foam filling is eight times more breathable than standard toppers, which means air circulates freely to stop heat building up during the night. It's non-allergenic, making it suitable if you're sensitive to dust or allergens, and the durable cover protects the foam while staying easy to maintain.
The breathable design allows air to flow through the topper, keeping things fresh and comfortable while you rest. It's made to fit mattresses measuring 200cm by 180cm, so it works perfectly with super king beds. The cover wipes clean when it needs refreshing, which keeps care simple and straightforward. Whether you're looking to add extra support to an older mattress or just want a cooler night's sleep, this topper delivers practical comfort you can rely on.

Customers Say
Comfortable mattress topper improves sleep and eases aches, but many users report it slips on the bed due to lack of securing straps and some find it less firm than expected.

Not as comfortable as I thought it would be.
I am not sure it is worth the amount of money paid. A previous topper mattress I was using was much more comfortable. This new one is taking time to get use to. I expected something a lot more comfortable.

Great overall but could do with straps
I bought this to add some comfort as i was having back ache due to my current mattress. This adds that feeling of sinking in and added comfort i was looking for. I am overall happy with my purchase however it can slide on the bed, i think with added straps i would have rated this 5 star.
