The Casper dog bed was an instant hit at our house. Not only did our dog Gracie like it right away, I found myself trying it out for comfort and I was SO impressed. The bed is so dense that even when you push, you can't feel the floor. The covering is excellent and very washable. The large is so roomy that I curled up with Gracie the day it arrived and we both fell asleep. Now we are looking at ordering a King size Casper mattress for ourselves.
