Every Posh Tag mattress protector is diamond quilted in 200 thread count microfibre, with a 360° stretch elastic skirt that fits mattresses up to 30cm deep. Choose the quilted protector for everyday comfort and protection, or the quilted waterproof version when you need a liquid barrier as well.
Both are made in all five UK sizes — single, small double, double, king and super king — and both are machine washable and safe to tumble dry on a low heat, so your bed is made up again the same day.

Frequently asked questions
What does a mattress protector do?
It sits between you and your mattress, taking the sweat, skin and spills that would otherwise soak in. It keeps the mattress clean, helps it last longer, and protects the warranty on many mattresses.
What is the difference between a mattress protector and a mattress topper?
A protector shields the mattress and adds very little height. A topper is thick and changes how the bed feels. Ours is a protector — it adds a soft quilted layer without altering the firmness of your mattress.
Should I choose quilted or waterproof?
Quilted is the everyday choice. Waterproof does the same job and adds a liquid barrier, which is what you want for children, pets, illness or incontinence.
Will it fit a deep mattress?
The skirt is 30cm deep, so it fits mattresses up to 30cm. Measure your mattress before ordering.
Can I tumble dry a mattress protector?
Ours can be tumble dried on a low heat — many waterproof protectors cannot. Do not bleach, iron or dry clean.
How often should I wash it?
Every two to three months for normal use, and straight away after any spill.
