A UK king size mattress measures 150 × 200cm (5ft), and our king size mattress protectors are cut to fit it properly. Both options are diamond quilted in 200 thread count microfibre with a 360° stretch elastic skirt that grips mattresses up to 30cm deep.
Choose the quilted protector for everyday comfort and protection, or the quilted waterproof version if you need a liquid barrier as well. Both are machine washable and safe to tumble dry on a low heat.

What size is a UK king mattress?
150cm wide by 200cm long, sometimes described as 5ft. This is different from a US king, so check before ordering from overseas listings.
Will it fit a deep king mattress?
The skirt is 30cm deep, so it fits king mattresses up to 30cm. Measure from the top of your mattress to the base before ordering.
Should I choose quilted or waterproof?
The quilted protector adds a soft layer and protects against everyday wear. The waterproof version does the same and adds a liquid barrier — the right choice for children, pets, illness or incontinence.
Can I tumble dry a king size protector?
Yes, on a low heat. Do not bleach, iron or dry clean.
How often should I wash it?
Every two to three months for normal use, or straight away after a spill.
