About the TheraPur Cool Mattress Protector

Last checked

Buyers looking to soften and protect a deep mattress, rather than create a spill barrier, are the right starting point for the TheraPur Cool Mattress Protector. It is a quilted protector with a cool-touch cover, breathable fillings, hypoallergenic construction, a 40°C machine-washable care route, adjustable straps and a 1-year guarantee. The most useful hard spec is depth: fitting mattresses up to 42cm is generous for a strap-on protector, especially with modern pillow-top and hybrid mattresses getting taller, but straps are less secure than a full fitted-skirt design because they anchor the corners rather than wrapping the whole mattress edge. The strap format is the trade-off. The cooling language also needs reading carefully: this is a soft-touch, moisture-wicking comfort layer, not a powered cooling system or a specialist phase-change protector. Against basic cotton quilted protectors, the cool-touch cover is the upgrade; against waterproof PU-backed protectors, it is less about accidents and more about feel, airflow and mattress surface hygiene. The washable, hypoallergenic quilting is an honest practical feature for keeping a mattress fresher, though adding any padded layer inevitably changes the feel of the mattress underneath.

Used over a firm or gel-topped mattress, this suits someone who wants a slightly cushioned, removable layer without masking the bed completely. Happier accounts describe a thick, good-quality protector that stays put well under the mattress, adds a little comfort and washes easily; one recent account also says the cooling feel of an ActiGel mattress could still be felt through it, although slightly dulled. Heat is the central fault line. Low-scoring accounts repeatedly say the protector made no cooling difference, and several say it actually made the bed feel warmer, which contradicts the all-year cooling pitch and suggests the cool-touch surface may be more noticeable at first contact than over a full night. A detailed poor account also flags rough, rustly fabric and corner straps stretched hard on a deep mattress, so restless couples may find movement noise more irritating than the spec implies. Spill protection expectations need managing as well: one recent account points out that it is not waterproof, and the product description gives no reason to treat it like a waterproof protector. If the priority is a washable, deep-fit quilted protector with a little extra comfort, this works. If the priority is reliable cooling for hot sleepers or accident protection, a phase-change cooling protector or waterproof breathable fitted-skirt tier makes more sense.


Pros and Cons

Pros

  • Thick protector includes straps that keep it securely in place on the mattress.
  • High-quality materials contribute to a more pleasant sleeping experience.
  • Effective at prolonging mattress life by providing an extra layer of protection.
  • Easy to wash at 40°C, making maintenance hassle-free.

Cons

  • Some customers reported that it traps heat instead of cooling during the night.
  • Material feels thick and noisy, causing disturbances when moving.
  • Elastic straps can stretch too tightly, risking fabric damage over time.
  • Not waterproof, which limits its protective capabilities against spills.

You can still feel the coolness of the actigel mattress through this protector, but it does lessen the effect. I like the elasticated bands that you loop under your mattress to keep this on. The only downside is that the protector is not waterproof.

Works well with the robinson foam mattress. Bought it as memory foam has a reputation for being very warm and this is wicking. Happy so far
