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.

Quality mattress topper
Very pleased with this mattress topper for the price. I use it under another mattress topper which is thicker and is great for adding extra depth - get a better night’s sleep even though an insomniac.
