What Is a Mattress Protector?
A mattress protector is a layer that goes over your mattress that can be taken off and washed. It protects your mattress from dirt, sweat, spills, dust mites and general wear and tear. It usually sits under your fitted sheet and can look like a thin fitted sheet, a quilted pad, or a fully encasing cover with a zipper.
Some common types in the UK include:
- Quilted mattress protectors – usually lightly padded for added comfort and warmth.
- Waterproof mattress protectors – features a protective backing (often PU) to protect against spills and accidents.
- Fully encased protectors – zips around the mattress to protect against allergens and bed bugs.
A mattress topper is designed to change the feel of the bed (softer, firmer, more supportive), while a mattress protector is made to protect the bed.
What Does a Mattress Protector Do?
A mattress protector has several important roles:
- Protects against spills and stains: Perfect for households with children, pets, or for anybody who likes a cup of tea in bed. A stained mattress can be difficult or even impossible to clean, and many UK mattress warranties are voided by visible stains.
- Reduces wear and tear: By acting as a barrier between your body and the mattress, it helps prevent premature sagging and discolouration.
- Improves cleanliness: Every night while sleeping, people lose moisture and skin cells. A protector catches most of this, and can then be washed in the machine. This helps limit dust mites and odours.
- Supports allergy management: For people who are allergic to dust mite or pets, some protectors can reduce exposure when washed regularly.
- Adds a little comfort: Quilted protectors can make the mattress feel a little softer without changing the feel of the mattress too much.
A mattress protector helps keep the mattress in better condition for longer, which is especially important because of how expensive mattresses are in the UK.
