My 75 pound lab LOVES this bed and spends so much time in it that she'll drag it from room to room or to the basement so that she can curl up in it while we're watching movies. It's tough to get her out of it sometimes and into her kennel. The shape and sides have stayed true to form the last 3 months and it's easy to remove the cover and wash when needed. We really like the design of this bed and it isn't an eyesore when left out in our living room when we entertain. 

She fits in the large sized bed just fine, curled up or splayed out. 5-stars!
