About this product
Revive your mattress with this dual-layer topper that lets air flow freely around your body for a breathable, comfortable night's sleep. It's filled with plump hollowfibre and features a clever air mesh construction that keeps you at just the right temperature, whatever the season. The extra deep 8cm design adds supportive cushioning that makes your existing mattress feel refreshed and inviting. It's sized to fit king size beds, and the elasticated corner straps stretch over your mattress to hold everything securely in place without shifting or bunching up.
The dual construction allows air to circulate between the layers, which helps regulate temperature and keeps you comfortable throughout the night. The air mesh sides work with the hollowfibre filling to create a topper that's soft yet supportive, bouncing back night after night. The elasticated straps make fitting quick and simple, gripping your mattress firmly so you don't need to worry about it moving around. Whether you're looking to extend the life of your current mattress or just add an extra layer of comfort, this topper delivers practical benefits you'll notice from the first night.

Customers Say
Comfortable, soft mattress topper that improves sleep quality and relieves back pain. Breathable with good airflow, fits well with elastic straps. Some find it thinner than expected and less supportive.

Added comfort to the mattress.
Bought to add support to the mattress on our sofa bed. Excellent results. Quite soft and squishy. Great night’s sleep.

Not a mattress topper, more of a duvet
In the process to return as this is not a mattress topper, just a thick duvet

Comfortable and breathable
I bought this back in December and it's been great. A bit elastic, soft, and spongey, it greatly improved the sleep quality on the thin mattress we have. My back is much happier for buying this.
Annastiina, 25 - 34

Great item
Packaged well, easy to carry home with handles. Sprang into shape nice and quickly. Slept on it last night and it's very comfortable
Kim26, 65 or over
Could be better
Not as good as I hoped it would be, no extra support afforded by this topper, there is most likely better products out there
