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 improves sleep quality and relieves back pain. Good thickness and fit with elastic straps. Some find it too warm or less supportive; durability varies.

Great value
Been using it for about a week now. Very comfortable, feels more luxurious than what I expected for the price. Certainly has saved me having to buy a new mattress for a while that’s for sure.

Great topper
Bought this for my daughter as the mattress in her new student house was a little on the thin side to say the least and was giving her backache! This has done the trick! Apparently it’s very comfy and snuggly and no more backache

Over-Priced
Came quite squished in the packaging and never puffed up. I bought it because I was having hip pain sleeping on my side, but this hasn't helped. My previous mattress topper attached to the mattress with big elastic straps top and bottom which was much more secure than this one which attaches with small elastic straps on each corner. I don't think this is worth almost £50.

Excellent purchase
Only purchased 5 days ago but massive difference. Allowing my mattress to last a little bit longer. When you open the topper give it a few hours to open properly. Really shake it out. My mattress was starting to sag. This topper will give me enough time to find the mattress I want, totally worth buying.

Makes a hard mattress softer.
I bought this a few days ago and have had a good chance to use it in the early July hot weather. I am very pleased with the purchase. The mattress is very hard and the topper makes it much softer, which is the reason for buying it. Very good value for money.

Easy solution to an uncomfortable problem
Have been sleeping in the guest bedroom as it is cooler and it did not take me long to realise how hard and uncomfortable the mattress was. A mattress topper seemed to offer a reasonably priced solution and I was right. The 8cm topper has made the mattress far more comfortable, so much so that I’m glad I bought a second one for the main bedroom when the weather eventually cools down.

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.
