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.

Customers Say
This mattress topper greatly improves comfort, softness, and sleep quality, especially on firm or lumpy mattresses. It fits well, stays in place, and offers good value, though some find it thinner than advertised.

Full marks, now everyone wants one!!
bought for my daughter to provide extra cushioning for her, to help her sleep better. she loves it. i was worried it might make her too warm, or make it feel too soft. but she says it works too well, she doesn't what to get out of bed, so now i have to get another for her sister!! fits like a sheet, not just elastic on the corners, so easy to put on and shouldn't stretch out of shape or anything. I would recommend.

ZZZZzzzz...
Extremely comfortable, can't feel the bed springs anymore! Fits the bed perfectly & doesn't move about like my old one did. Very happy with it & for just a little over £30 is good value too.
