Pleasantly surprised!
Color: Beige, Size: 35" x 23"x 3.5"
This bed is thick, plush, soft and has both a furry plush side and a cooler canvas side. It's the perfect size for my dog's crate and he does seem to really enjoy laying on it. It's super easy to clean - washes up nicely on delicate and with a low tumble dry. I had no issues waiting for it to fluff up after being unpackaged, too. It was good to go by that evening. I was expecting, at this price point, something flimsy with loose threads. Overall, I think it's much thicker and nicer than I was expecting for the price! Thinking about grabbing another one before they disappear!

Thick and soft
Color: Grey, Size: 35" x 23"x 3.5", Color: Grey, Size: 35" x 23"x 3.5"
We and the corgis love the bed. We got the large size so that both corgis could be on it together so the large size is perfect for 2 small to medium breed dogs that like to snuggle/sleep together. The bed is surprisingly thick and soft and well made. It appears that it will be fairly easy to machine wash and dry and I suspect if the pups do not decide to demolish it like they do their stuffy toys, it will last a good long time. It is definitely a good buy for the money.

Fluffy
Color: Beige, Size: 35" x 23"x 3.5", Color: Beige, Size: 35" x 23"x 3.5"
I purchased the 35x23” in beige. I know this is a dog bed, but I am using it as a comfy mat in my prayer room. It’s nice and soft and fits right where I needed it. Perfect for when I get on my knees to pray at the cross.

Perfect fit in my dog crate, nice loft to it
Color: Grey, Size: 35" x 23"x 3.5"
Really nice dog bed, fits perfectly in the crate that I have. This thing is rather large and bulky and difficult to wash. I wish that there was a zipper on it and that you could remove the stuffing so that you can wash just the cover. Before putting it inside the dog crate, I had it on my couch. My daughter thought it was a new pillow for her to use and was bummed when I told her it was for the dogs. She liked it and thought it was quite comfortable.
