A UK double mattress measures 135 × 190cm (4ft 6in), and our double mattress protectors are made to that size. Both are diamond quilted in 200 thread count microfibre with a 360° stretch elastic skirt that fits mattresses up to 30cm deep.

Pick the quilted protector for comfort and everyday protection, or the quilted waterproof version when you need a liquid barrier too. Machine washable and safe to tumble dry on a low heat.

Size and fit

Frequently asked questions

What size is a UK double mattress?

135cm wide by 190cm long, also called 4ft 6in. If your mattress is 120cm wide, you need a small double instead.

What is the difference between a double and a small double?

A double is 135cm wide, a small double is 120cm. The 15cm difference matters — a small double protector will not fit a full double.

Will it fit a deep double mattress?

The skirt is 30cm deep and fits mattresses up to 30cm. Measure your mattress depth first.

Can I tumble dry it?

Yes, on a low heat. Do not bleach, iron or dry clean.

Should I choose quilted or waterproof?

Quilted for everyday comfort and protection; waterproof if you also need a liquid barrier.
