The Casper mattress protector is the first protector I’ve reviewed that looks and feels like a mattress pad and mattress protector hybrid. It has a quilted feel that is luxurious but provides the same level of protection that a protector would. I used it on my Casper mattress, but it fits other mattress types as well. Read on for my full review.
Adding a waterproof protector to your mattress helps protect the longevity of your mattress and your mattress warranty. Fluid/water damage or spills can void your mattress warranty and leave it 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 ozs 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.
When I came back and ran my hand underneath the protector, I felt no moisture, dampness or any leaks. The protector passed my waterproof test!
Size: I use a Casper mattress, so the protector fit snugly around my bed. But if you use a different mattress and find that it is not the perfect fit, Casper encourages you to wash and dry the protector:
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 have reviewed, I was curious about how it would breathe with both a quilted layer and a waterproof layer built into one product.
Casper says that the protector has three layers: two knit with a waterproof layer (PE) in between.
They say: 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 a noise or rustle underneath your sheets.
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 avoid shifting, which can make noise as well.
The Casper mattress protector ranges from $75 for a Twin/Twin XL to $95 for a King. Queen mattress protectors are $85.
If you own a Casper mattress or are interested in protecting your mattress by adding a thicker/softer layer, I would definitely consider the Casper mattress protector.
Because this protector offers comfort, breathability and waterproof protection I think it’s worth the value. Make sure to check out our overall mattress protector reviews.
