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 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-based 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 limited warranty, which you can read more about here.
