| Emma Select | Yes | 40C | Soft and quiet in store |

| Teflon Supreme Care | Water resistant | Machine wash | Not waterproof |
Unhappy owners of the Dreams Waterproof Anti-Allergy Mattress Protector also describe a hot bed. One found it uncomfortably hard and another couldn't feel the new mattress through it. Emma's Protector listing says "Breathable, comfortable, and entirely crinkle-free", while owners describe rustling and a plastic-bag feel. I think "entirely" is an ambitious word to put next to crinkle.
The separate Emma Select Mattress Protector is the waterproof option I'd investigate first for quietness. In our showroom check, it had a soft, flexible top that draped well under a fitted sheet, with no crinkle when tugged and none of the plasticky barrier feel of cheaper waterproof layers. That's a handling observation, not a promise about sleeping temperature.
Choose waterproof only when spills are a real risk
The Simba Sleep Performance Protector is my pick if you want a washable layer without waterproof backing. It has a cotton cover and cotton filling, with no waterproof membrane, and washes at 40C. Your bedtime tea still needs a steady hand.
One Simba owner found it hot and loud, and another found the edges didn't sit flat. I'd still take the plain cotton build when waterproofing has no job to do on your bed. Cotton isn't a guarantee of a cool night, but a waterproof layer isn't a free extra either.
If liquid protection is essential, avoid Teflon Supreme Care. It isn't waterproof: it's water resistant and stain repellent, and a couple of owners expected waterproof protection. A waterproof protector makes just as much sense on an adult bed as a child's if spills or accidents are likely.
For anti-allergy protectors, check beyond the label
Among the protectors with a stated wash temperature here, Tempur Home is the option that allows 60C. The Tempur Home Mattress Protector combines a waterproof membrane with that hotter wash. Check the care label before buying rather than assuming every anti-allergy protector can go through the same cycle.
Owners call Tempur slippery and sweaty. I'd skip it unless I needed the hotter wash. Emma Select's Purotex treatment, Simba's anti-dust-mite treatment and iGel's dust-mite build-up claim are the makers' claims; don't use those names as a substitute for the care instructions. "Hypoallergenic" alone wouldn't decide the purchase for me.
For medical guidance rather than product wording, read the NHS advice for allergic rhinitis. If you're also replacing the mattress, use the anti-allergy mattress selection to compare practical features.
Match the UK size and the full mattress depth
Standard UK mattress sizes include single at 90 x 190cm, small double at 120 x 190cm, double at 135 x 190cm, king at 150 x 200cm and super king at 180 x 200cm. Match the protector's dimensions to your mattress, especially if you're buying for an imported or non-standard bed. A double protector isn't simply a tighter-fitting king.
A protector with a skirt shallower than your mattress won't fit, especially on a deep hybrid. Measure from the base of the mattress to its highest sleeping surface. Include any mattress topper you intend to keep underneath the protector. The mattress size on your receipt won't tell you whether the corners will stay covered.
The Dreams Waterproof Anti-Allergy Mattress Protector fits mattresses up to 38cm deep. Simba and iGel have 40cm skirts. Match the stated fit to your measured depth before buying. A generous-looking elastic edge is no reason to guess, and the person adding it at the till won't be there to put the corners back on.
"Mattress cover" is a loose shopping term. Check whether you're buying a fitted protector for the sleeping surface, a replacement outer cover or a zipped encasement that surrounds the mattress. They aren't interchangeable, and none is automatically waterproof. A protector normally sits beneath your fitted sheet; it isn't a substitute for one.
Check washing and drying before you buy
A washable protector is only useful if its care instructions suit your laundry routine. Check the permitted wash temperature and whether tumble drying is allowed. Don't assume the cotton top and waterproof backing can tolerate the same treatment as your sheets, and let the protector dry fully before putting it back on.
If a spill reaches the mattress, blot it, use a little mild soap where the care instructions allow, and let it dry fully without soaking it. I've done that job myself. Which, yes, is the job a protector would have saved me. I know.
