Cozy, put you'll need to clean your washer and dryer
Size: 35 in
My dogs LOVE this bed. It's plush, comfy and cozy. Downside, washing and drying it even on cold and low settings - the black backing sheds and covers the inside of washer and dryer. It's easy enough to do. I've washed them twice now and has happened both times.

Lasted only 2 years normal wear
Size: 23 in
Soft and loved by dog. However after 2 years of washing every other month, it exploded in washer clogging drains and making mess.
