Kezia is a 13 1/2 yr old Labradoodle, that is beginning to show her age..being stiff when she gets up and moving often during the sleep cycle from one bed to another.  One of her beds was too easily compressed.  I ordered the Casper dog bed for her comfort and ease of sleep. It took only one hour of rest on the Casper dog bed and she was hooked. and Now it is her bed of choice.  Thank you Casper.
