WILL A CASPER MATTRESS FORM A VALLEY LIKE MY OTHER MATTRESS DID?
Each Casper mattress is designed with foams that retain bounce and remain supportive night after night, throughout your life with the mattress. With the correct support underneath, your Casper will perform as it should and you can sleep well night after night! As a foam mattress, your Casper will need a firm, flat, surface. We also recommend rotating the mattress every 6 months for even wear. It's actually covered in our 10-year warranty, which you can read more about here.
