Care And Warranty

As with all mattress protectors,  it is important to make sure to follow the care instructions carefully for the specific protector.

The instructions are simple for this protector: machine wash cold and low tumble dry. I had no issues with durability or shrinking when I washed and dried my protector.

Drying a mattress protector (at least the waterproof ones) on a heat that’s too high can potentially damage the waterproof membrane of the protector. This will allow leaks and spills to get through the protector and onto the mattress, thus violating the mattress warranty.

There is no trial or return policy with the Purple mattress protector. They say this is “due to the nature of the product,” but I’m not really sure what that means since plenty of other mattress protector brands offer returns if customers aren’t satisfied.

Purple does offer a one-year warranty on its mattress protector, and more information about the warranty on the company’s website is available here.

The Waterproof Test

Purple is a relatively big player in the mattress industry. (Check out our review of the Purple mattress here.) This means the company knows that adding a protector can spare the mattress from warranty violations caused by liquid/water damage.

The protector is the same material on all five sides, which means it can protect a mattress from spills on the surface and down the sides.

Purple says its protector is water-resistant and water-absorbent. I put those claims to the test by pouring 10 oz of water into a concentrated area on the protector. I wanted to mimic a large spill or accident. (I do this with all my waterproof mattress protector reviews.)

The water immediately pooled into a spot on the bed and eventually, some of it absorbed into the layers of the protector.

I left the water there for an hour (something that could happen if there is an accident in the bed overnight). I had no issues with leaks, dampness, or moisture underneath my protector. It didn’t fully absorb the water, but it passed my waterproof test!

Additional Considerations

Size And Noise

The Purple mattress protector comes in sizes that range from Twin to California King (including Twin XL and Full XL).

Purple says its protector is designed to “complement” its own mattresses, but the protector should fit any mattress up to 13″ thick.

I sleep on a 10″ thick Casper mattress. The protector went on very easily and stayed fairly secure thanks to the strong elastic. I did have some extra material to deal with, because my mattress is not as thick as the Purple mattresses. This caused some creasing and shifting at night as well as some crinkling sounds.

RELATED: Mattress Sizes

The mattress protector is virtually unnoticeable, but it does have more of a “plastic” like feel to it than some of the other quilted mattress protector options out there. Depending on how thin the sheets are, some people might feel it more than others.


The Purple mattress protector is a unique material that is stretchy and soft, not like terrycloth or cotton quilt. It is comprised of polyester and a little bit of spandex.


The Purple mattress protector is slightly more expensive than other thin mattress protectors I’ve reviewed. A Queen size protector is currently sold for $59 at full price on Purple’s website.

I think there was just a little too much extra material for a 10″ mattress. This can leave some creasing and shifting that might be pretty noticeable to some.

I feel like those who sleep on a Purple mattress would enjoy this protector. It is stretchy and probably fits their mattresses perfectly. The protector may also be a good fit for those who are looking for a thin, water-resistant protector but don’t want one with a terrycloth or cotton/quilted surface.
