Bought for my son, says he is happy with the Mattress Protector, though bought similar in the past, from another branded store, and the backing started to disintegrate over time, time will tell with this item from M&S.

Bought this protector to replace an old one. The previous was heavy and difficult to fit in the washing machine. This one is much lighter fits very well and will be much easier to wash and dry. Good deep sides that ensure the topper covers the mattress.
