Great!
I had purchased 2 of the KLIMBs after seeing how the trainer I went to used them. I didn't want my puppy falling off of them so I purchased mats. They fit perfectly and really do make a difference. I think Tobi feels much more secure and I don't get worried if he hops up there with a little more energy. They do fall off readily when you are carrying the KLIMBs so just be aware.
