Waterproof Test
Adding a waterproof protector to the mattress helps protect the longevity of the mattress and ensure that it doesn’t void the mattress warranty. Fluid/water damage or spills can void the warranty and make the mattress susceptible to mold and other issues. One of the nice things about the Casper mattress protector is that it has a thin layer of polyethylene (PE) sandwiched between polyester knit, so it doesn’t have a rough feel or make squeaky or noisy sounds. To test the waterproof properties of the protector, I poured 10 oz of water into a concentrated area of the mattress protector to mimic a spill or accident. I left the water there to be absorbed for a couple of hours.

Size
I use a Casper mattress, so the protector fit snugly around my bed. But if people use a different mattress and find that it is not the perfect fit, Casper encourages them to wash and dry the protector. From Casper’s site: The great thing about that skirting material: it might appear larger right out of the package, but it’ll shrink to fit perfectly on the bed once it’s on. The sides are fully intended to be tucked into the foundation or frame if necessary. If you are finding it to still be on the bigger side, give it a quick wash and it should be fine!

Breathability
Since this mattress protector has more of a mattress-pad-type feel than others I’ve reviewed, I was curious about how it would breathe with both a quilted layer and a waterproof layer built into one product. Casper says the protector has three layers: two knit layers with a waterproof layer (PE) in between. From Casper’s site: In the protector, the protective film is sandwiched by a polyester knit fabric — the same material used in premium athletic wear to keep people cool. It has an integrated spacer layer, so air flows through it easily to keep things nice and breezy. I had no issue with breathability when I used this protector. I enjoyed the soft feel under my sheets.Noise
With many waterproof mattress protectors, the waterproof barrier can sometimes create noise or rustle underneath the sheets. On this protector, the polyester knit fabric that sandwiches the waterproof film in the protector helps keep the noise to a minimum. The unique skirting material hugs the sides of the mattress and helps prevent shifting, which further reduces noise.
