Emma Waterproof Mattress Protector im Test

The Emma Waterproof Mattress Protector is a fitted, sheet-style protector in 100% polyester with a polyurethane membrane that stops liquids reaching the mattress, sold in eight UK and EU sizes from £61 for a UK single. It is a plain, secure waterproof layer rather than a padded or cooling one.

Why a mattress protector is worth it

A mattress soaks up more than spills. Bed Advice UK, the consumer site of the National Bed Federation, says we lose around half a pint of fluid each night and shed over a pound of dead skin cells a year while we sleep. Its bed care guide simply says to always use a mattress protector, and its topper guide suggests owning two so one can be in the wash.

How the Emma protector is made

Emma’s product page describes a polyester protector with a polyurethane film that makes it waterproof, cut like a fitted sheet rather than held by four corner straps, so it follows the mattress closely and does not slide. Emma lists each size for a 25 cm deep mattress and says it is compatible with all Emma mattresses and toppers. The membrane can crackle for the first few nights, and Emma suggests an extra wash to soften it.

Sizes, weights and prices

Prices are Emma’s regular prices, checked on 28 September 2026. At the time of writing (September 2026), Emma also includes the protector free with many of its mattresses as a bundle offer.

Care and returns

• Machine wash at up to 40°C, never hot, and do not dry clean or iron it.
• Emma suggests washing it about once a month, or straight away after a spill.
• Returns are possible within 14 days, but Emma’s trial page limits them to protectors in brand-new, resalable condition for hygiene reasons, so this is not a sleep trial.

Who it suits

Families with young children, pet owners and anyone who wants to protect a new mattress under its guarantee. Emma publishes no warranty length for the protector. If you sleep hot, a protector with a cooling fabric may suit you better, because a waterproof membrane under polyester is not designed to move heat.
