Designed by the same engineering team behind all of Caspers sleep products the dog mattress is a universally comfortable sleep surface for our four-legged friends. We combined our mattress-making know-how with extensive dog-centered research to create a sleep environment that caters to canines natural behaviors. Pups spend more than half their lives sleeping. If any species deserves an outrageously comfortable sleep surface its dogs. So we combined pressure-relieving memory foam and durable support foam to create a bed that loves Fido back.
