About this product
Add gentle support and comfort to your existing mattress with this topper that refreshes your bed and helps you settle into a deeper sleep. It's designed with an extra 10cm depth that creates cushioned layers, so you'll feel supported throughout the night. The quilted cover has stitched sections that keep the hollowfibre filling fluffy and evenly spread, which means it maintains its shape beautifully over time. Suitable for king size beds, it fits securely with elasticated corner straps that hold it firmly in place without shifting around.
The microfibre cover feels soft against your skin and it's machine washable at 40C, so keeping it fresh is straightforward and hassle-free. The hollowfibre filling is non-allergenic, which makes it a great choice if you're sensitive to allergens. It's tumble dryer safe too, so you can get it back on your bed quickly after washing. Whether you're reviving an older mattress or adding extra comfort to your current setup, this topper delivers the support you need every night.

Amazing nights sleep
Literally the best thing I have ever bought. I have been suffering with a lumpy old mattress with metal springs digging in me for far too long. This was a last ditch attempt to save money on a new mattress after a friend recommended it and I am.so glad I gave it a try. It is like sleeping on a cloud and my nighttime is transformed.

Rubbish
10cms it is not. It’s about 3 and goes flat as a pancake when you lie on it. Bought it to replace an old one, which had I have known how rubbish it is I wouldn’t have bothered.
