Does it really feel cool?

The top has a cool-to-the-touch finish, but most owners say the effect is mild and fades after a few nights. It is not a substitute for a cooling mattress or pad.

Will it fit a deep mattress?

It is a fitted Queen protector with stretch sidewalls. Owners with thick pillow-top mattresses report a tight fit, so check your mattress depth before buying.

Most owners find it quiet under sheets. A few notice a light crinkle from the waterproof layer when moving.

Does it protect against bedbugs or dust mites?

It works as an allergen barrier and keeps spills off the mattress, but it is not a full zippered encasement, so it does not seal the mattress on all sides.

It is machine washable; follow the care label and tumble dry low or line dry to protect the waterproof backing.

Is it worth it over a plain mattress pad?

A plain pad adds cushioning but lets spills through. This one adds waterproofing and an allergen barrier for less than most branded cooling protectors, at the cost of padding.

Our take on the Mainstays Cooling Waterproof Fitted Mattress Protector

The Mainstays Cooling Waterproof Fitted Mattress Protector is a Queen-size fitted cover with a cool-to-the-touch top and a TPU waterproof backing. It shields the mattress from spills and stains and acts as an allergen barrier. Stretch sidewalls make it quick to put on and take off. It suits renters, families with kids or pets, and anyone who wants spill protection without a bulky encasement. Against quilted or terry-topped protectors it is thinner and less padded, and it costs far less than branded cooling protectors. Owners rate it well overall, though some say the cooling feel fades and the fit runs snug on deep mattresses.
