We felt the protector should be a silent partner in crime: so light and durable you forget you have it — until an emergency makes you thankful you do! In a practical sense, it is needed to protect against almost anything and fit snugly on your mattress, without compromising airflow. The Casper Bedding 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 so your protector stays clean and dry. The protector's unique skirting offers a superior balance of stretch and recovery to fit your mattress like a glove. This 360-degree grip prevents shifting, and the cross-directional stretch and machine-directional elastic allow the fabric to move with your mattress instead of popping off. We included Casper Bedding labels on your protector to indicate the head and foot of the bed and make life easier.
This is our second Casper waterproof mattress protector. We replaced the first after five years with the same one because we love it so much. It’s easy to wash and dry and truly has helped keep our mattress clean and dry from accidents.. Jessica. Mahopac, NY. Thu May 21 2026
