IF I DON'T BUY YOUR MATTRESS PROTECTOR (OR USE ONE AT ALL), IS MY CASPER MATTRESS WARRANTY VOIDED?

We really recommend using a protector, or at the very least, a fitted sheet, with your Casper mattress. Doing so will not only increase the lifespan of the mattress, but it will make life a lot easier! The warranty will not be affected whether or not you have a mattress protector.
