## Overview

The Casper Sleep Waterproof Mattress Protector offers a state-of-the-art waterproof yet breathable barrier that guards your mattress against spills, dirt, and wear. Engineered with a unique 360-degree elastic skirting, it fits mattresses up to 16 inches thick securely without shifting or noise. Made from advanced polyester film used in outdoor gear, it maintains mattress comfort and temperature balance while being machine washable for easy care.

## Description

We felt the protector should be a silent partner in crime: so light and breathable you forget you have it — until an emergency makes you thankful you do! In a practical sense, it needed to protect against almost anything and fit snugly on your mattress, without compromising breathability. The Casper mattress protector won’t change the comfort of your mattress or affect the temperature. After several rounds of thermal and humidity testing, we settled on the optimal film for spill protection and breathability. It happens to be the same kind used in state-of-the-art outdoor gear. The protector's unique skirting offers a superior balance of stretch and recovery to fit your mattress like a glove — accommodating mattresses that are up to 16 inches thick. This 360-degree grip prevents shifting, and the cross-directional stretch and machine directional elastic allows the fabric to move with your mattress instead of popping off. We included Casper labels to indicate the head and foot of the bed and make life easier.

I recently purchased the “Casper Sleep Waterproof Mattress Protector, Queen, White” and I couldn’t be happier with my decision. This mattress protector has exceeded my expectations in every way. First and foremost, the waterproof feature is outstanding. It effectively protects my mattress from spills and accidents, giving me peace of mind. Despite being waterproof, it remains breathable, ensuring that my mattress stays cool and comfortable throughout the night. The fit is perfect. The unique elastic skirting and 360-degree grip ensure that the protector stays securely in place, even with a lot of movement. It fits my queen-sized Casper mattress like a glove and doesn’t shift or bunch up. One of the best aspects is that it doesn’t affect the feel of my mattress. The protector is quiet and doesn’t create any crinkling noise, which is a common issue with other waterproof protectors. It feels soft and smooth, adding an extra layer of comfort without compromising the original feel of the mattress. Overall, I highly recommend the “Casper Sleep Waterproof Mattress Protector” to anyone looking to protect their mattress without sacrificing comfort. It’s a bit on the pricier side, but the quality and peace of mind it provides are well worth the investment.
