I bought one of these from woot! earlier this month.
The Beast loves it!
I had a hard time figuring out how to keep the top half on! Then I noticed the zipper. It took a few minutes, but I finally did it.
It is nice to be able to remove the top when (IF) warmer weather ever gets here. It also has a nice removable cushion
I did not get a photo of it but there is a cutout on the back of the top in the shape of a paw print so that The Beast will not get too warm AND she can also be on the lookout for sneak attacks by Butters!
