Mattress protector vs mattress topper — these two products get confused constantly. They serve completely different purposes. Here is the clear difference.

What is a mattress protector?

A mattress protector sits on your mattress under your fitted sheet. Its job is protection — keeping your mattress safe from sweat, spills, dust mites and stains. It doesn't change how your mattress feels. It's thin, fitted like a sheet, and you barely notice it's there. A good waterproof mattress protector can extend the life of your mattress by years, and costs from £8.99.

What is a mattress topper?

A mattress topper also sits on your mattress, but its job is comfort. It adds a thick layer of padding — typically 4 inches deep — that changes how your mattress feels. If your mattress is too firm, too soft, or getting old, a topper gives it a new lease of life. Our 4 inch deep microfibre mattress toppers are the most popular choice for a hotel-quality sleep experience at home.

Do you need both?

Many people use both. A topper goes on first for comfort, then a protector goes over the topper to keep it clean. This is the setup used in most good hotels.

Which should I buy first?

If your mattress is comfortable but unprotected — buy a mattress protector first. Cheaper and more urgent.

If your mattress is uncomfortable or old — buy a topper first, then protect it.
