I purchased this bed because I am training my dog not to sleep in mine. She is 40 pounds and medium size. If she were any bigger I'd have gotten the next size up. She fits in the bed just fine because she likes to curl up in a ball against something soft or sleep with her head resting on the "wall" of the dog bed. So far it has held its shape and she seems to enjoy it..climbed right in as soon as I opened it! I haven't washed it yet but the fabric seems durable and the seams are strong. The khaki color is a nice neutral beige that goes with my furniture. I have purchased cheaper beds that were flat or round but without the raised sides and my dog either peed on it and walked away or ignored it completely. This one is a success! Worth every penny.
