About this product
Keep your bed fresh and comfortable with this anti-allergy mattress topper that adds soft support and protection to your sleep space. It's filled with anti-allergy hollowfibre that works to remove common bed bugs and house dust mites, creating a clean, hygienic environment that's kinder to your skin. The soft-touch microfibre cover feels gentle and inviting, while the fitted design with elasticated corner straps keeps everything secure on your kingsize mattress. It adds an extra comfort layer that supports you through the night without changing the feel completely.
The hollowfibre filling is designed to offer soft, even support that adapts to your body. The elasticated straps grip each corner firmly, so it stays in place without shifting or bunching. It contains a biocide to help protect against bacteria and dust mite allergens, keeping your sleep space fresher for longer. The cover is machine washable and tumble dryer safe, which makes maintenance simple and practical. Whether you're refreshing an older mattress or adding extra comfort to a new one, this topper delivers protection and softness you can feel every night.

Customers Say
Sealy mattress topper is comfortable, well-made, and improves sleep quality. It fits well with corner straps, offers good value, though some find it thinner than expected or with lower-quality underside material.

Not a great buy
This topper was a low price & I needed one for a new sofa bed when I opened it at first inspection it looked good until I turned it over & saw the underside it is poor quality material but for the money & because I was going to use it I kept it but I don’t expect it to last long & will buy a much better quality when I need to replace it which I should have done straight away.

Sealy good!
It’s a good-quality mattress cover. It makes our bed more comfortable. It’s not too thick and it doesn’t make the bed too hot. It was easy to put on. You can’t ever go wrong with Sealy!

Comfortable cosy and cooling
I bought this after changing our divan which made our mattress feel hard. It is really comfortable, cooling yet not cold, cosy yet not too soft. My husband says every night he is glad I bought it and loves it. Gave four stars only because I don't know how long it will last yet.
Reeta, 55 - 64

Bought this to cover a sofa bed mattress it’s thick and good quality and comes in its own bag. Worth the money.
