I bought two of these for my two dogs and they love them. We use them in the family room to keep the dogs off the sofa and it works really well. 

I like them because they are square and utilize the space better than the round ones we have. Also, the dark color helps them blend in better with our hardwood floors.

The reason I give them a 4 vs. a 5 is because they are not as cushy as I thought they would be. This being said the photo shows a thinner pad, so maybe I should have known. I would still buy them again if I could not find a similar shape and size with a thicker cushion.
