This review is from my dog Beau, “I love my new bed. It’s cushy and fits my 15 pounds of fluff and fur beautifully. I can stretch out and sleep on my back if I want. I really appreciate that it didn’t have any funky chemical smell when it arrived. My mom ordered the sand color to match my fur. She says it looks just like the picture. It’s really soft and comfortable, I won’t leave it long enough for her to wash it. She had to order a second one for the kitchen so she could finally wash the original. By the way, it washed perfectly and didn’t shrink an inch. “
