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
One of my pups likes to attack his beds. This is a fine replacement at a decent price. I will say I was thrown for a loop buy the way it comes in the package. Once properly assembled the dogs took to it no problem.

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