Waterproof Mattress Protector 30cm Deep

The Waterproof Mattress Protector 30cm Deep has a 30cm pocket — one of the mattress protectors in our Waterproof Protectors range — that is how far the elastic skirt travels down the side of the mattress. It is the measurement people get wrong: a standard UK mattress is around 25cm, and a pillow-top or a memory foam mattress is often 30cm or more before a topper is added.

It is made in Single (90 x 190 cm), Small Double (4ft) (120 x 190 cm), Double (135 x 190 cm), King (150 x 200 cm), Super King (180 x 200 cm). UK bed names are consistent between retailers but mattress depths are not, so measure yours — including any topper — before choosing.

It is made in Standard (48 x 74cm). Those are the maker's own measurements rather than a standard size, so compare them against whatever you are replacing.

Wash warm and tumble low — high heat is what lifts a waterproof membrane off its backing, and a protector that has delaminated has stopped working without looking any different. Where the care label on the item differs from this, follow the label.

Fitting out a hotel, a B&B or a holiday let? Every bed in a let wants a protector. This line is stocked in quantity and wholesale beddings pricing is available on a trade account.
