She loves it, so that makes it a five star purchase. It’s super cozy soft. Just looking at makes ME want to take a nap 💤 🤭. Neutral color, large size, and supportive bolster. It looks nice and the material is thick and durable.

For the price it was a winner
Size: 23" x 23", Color: Beige

The middle part does not have enough filling. My dog will spin in circles trying to get comfortable and then lay somewhere else.
