Lopsided, but works
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
It's soft and good cat size. The bottom stuffing is uneven, so it leans a lot, no matter how I rotate it for the cat to try to even it out.
But the old cat loves it, especially since it's positioned in a perfect spot; a "corner" by a hallway, so it feels safe, while letting the cat see everything from that out of the way vantage point. I've been trying to get him to use beds again (had to throw some out b/c he gets seizures which can result in loss of bladder control). It only took a few days for him to "discover" the new bed, and start adding it to his nap rotations. and he looks so cute in it.

Super dog bed
Size: 23" x 23", Color: Beige
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. “
