Do I need a mattress protector?

Yes, if you want to extend the life of your mattress and keep it hygienic. A mattress cannot be machine washed, but a protector can. It sits between the fitted sheet and the mattress surface, creating a washable barrier against perspiration, skin cells, dust mites, and accidental spills. Over time, unprotected mattresses accumulate moisture and allergens that cannot be removed. A protector is one of the least expensive ways to preserve a mattress that may have cost several hundred pounds, and most can be machine washed at 40°C on a standard cycle.

What types of mattress protector does Belledorm offer?

Belledorm offers three types. Quilted protectors have a padded cotton or polyester top layer that adds a thin cushion of comfort alongside protection - the most popular general-purpose choice. Waterproof protectors have a TPU membrane backing that prevents all liquid from reaching the mattress, suited to children's beds, guest rooms, and anyone wanting full moisture protection. Fitted protectors are lightweight and unpadded, designed purely as a surface barrier with minimal change to how the mattress feels underneath. All three types are machine washable and available in sizes from single to super king.

Does a mattress protector change the feel of the bed?

It depends on the type. A quilted protector adds a thin layer of padding that you may notice as a slight softening of the surface - most people find this comfortable rather than intrusive. A waterproof protector using modern TPU backing is thin and quiet, with no noticeable crinkle or change in surface temperature. A fitted protector is the lightest option and makes almost no difference to the feel of the mattress at all. None of the three types are thick enough to significantly change the firmness or support of the mattress - for that, you would need a mattress topper.

What is the difference between a mattress protector and a mattress topper?

A mattress protector is a thin, washable cover designed to shield the mattress from moisture, dust mites, and wear. It does not significantly change the feel or firmness of the bed. A mattress topper is a thicker, padded layer designed to change the sleeping surface - typically softening a firm mattress or adding cushioning to an older one. Some people use both: a protector directly on the mattress for hygiene, with a topper on top for comfort, and a fitted sheet over everything. Belledorm offers both protectors and toppers in sizes from single to super king.

Do I need a pillow protector as well?

Yes, particularly if you want to keep your pillows fresh and extend their lifespan. Pillows absorb more moisture than mattresses because they are in direct contact with your face and breath throughout the night. That warm, damp environment is where dust mites thrive most quickly. A pillow protector creates a washable barrier between the pillowcase and the pillow filling, keeping the pillow cleaner for longer. Belledorm pillow protectors are available in standard and waterproof versions, both designed to fit standard UK housewife-sized pillows (50cm x 75cm).

What size mattress protector do I need?

Choose a protector that matches both the width and depth of your mattress. Belledorm mattress protectors are available in single (90cm), small double (120cm), double (135cm), king (150cm), and super king (180cm). For depth, check the skirt measurement on the protector against your total mattress depth. If you have a modern pocket-sprung mattress or use a mattress topper that adds height, you may need a deeper-skirted protector. As a general guide, if you use extra deep fitted sheets, you will likely need a protector with a matching deeper skirt.

How often should I wash a mattress protector?

Every one to two months under normal use. The fitted sheet on top handles the weekly washing and daily contact with skin, so the protector underneath does not need washing as frequently. Wash more often if the protector is on a child's bed, a guest bed that sees different users, or if a spill has occurred. Belledorm protectors can be machine washed at 40°C and tumble dried on a low setting. Avoid bleach and fabric softener, as both can damage waterproof membranes and reduce the protector's effectiveness over time.

Are Belledorm mattress protectors suitable for allergy sufferers?

Yes. All Belledorm protectors act as a physical barrier between you and the mattress filling, which reduces contact with dust mites - one of the most common triggers for night time allergies and asthma. Waterproof protectors offer the strongest barrier because the membrane prevents moisture from entering the mattress, removing the damp conditions dust mites need to thrive. For dedicated anti-allergy protection, Belledorm also offers hypoallergenic protectors that are specifically treated with an antibacterial finish for additional allergen management.

Waterproof Mattress & Pillow Protectors

Yes. Belledorm waterproof mattress and pillow protectors use a TPU (thermoplastic polyurethane) membrane backing that prevents liquid from passing through to the mattress or pillow underneath. This includes spills, perspiration, and any other moisture. The waterproof layer is bonded to the underside of the protector, so the surface you sleep on still feels like soft quilted cotton rather than plastic.

No. Belledorm waterproof protectors use a modern TPU membrane rather than the older PVC-style backings that were associated with a plastic feel and rustling noise. TPU is thinner, quieter, and more breathable than PVC, so the protector does not trap heat against the mattress surface or make a crinkling sound when you move. The quilted cotton top layer feels the same as a standard non-waterproof protector.

Yes. Belledorm waterproof protectors can be machine washed at 40°C on a standard cycle. Tumble dry on a low temperature setting. Avoid using bleach or fabric softener, as both can damage the waterproof membrane over time. Washing every one to two months is sufficient for normal use - more frequently for children's beds or if the protector has been exposed to a spill.

Yes. Belledorm waterproof pillow protectors use the same TPU waterproof backing as the mattress protectors. They have a zip closure that fully encloses the pillow, creating a complete barrier against moisture, dust mites, and allergens on all sides. The zip closure also means the protector stays securely in place inside the pillowcase and does not shift during the night.

Yes. The waterproof membrane acts as a barrier against dust mites, which thrive in warm, moist environments inside mattresses and pillows. By preventing moisture from reaching the mattress filling and blocking dust mites from passing through, a waterproof protector serves a dual purpose - liquid protection and allergen reduction. For dedicated anti-allergy protection, Belledorm also offers hypoallergenic protectors that are specifically treated with an antibacterial finish.

Belledorm waterproof mattress protectors are available in single, small double (4ft), double, king size, and super king. The standard waterproof mattress protector has a deep fit with a 38cm (15 inch) skirt depth, designed to accommodate modern mattresses including those with a topper. A 20cm depth version is also available for slimmer mattresses. Waterproof pillow protectors fit standard UK housewife-sized pillows (50cm x 75cm).

Yes. A waterproof protector is designed to sit directly on the mattress, with a fitted sheet placed over the top. The fitted sheet provides the sleeping surface, while the protector underneath handles moisture and hygiene. This also means you can wash the fitted sheet weekly (as most sleep hygiene guidance recommends) without needing to remove and wash the protector every time - the protector only needs washing every one to two months under normal use.
