My mom purchased this for my 1.5 year old. She seems interested, but they slide around way too much for her to actually climb on. I will get some Velcro, as I have read from other reviews that helps with the problem. It would be nice to have the bottom parts already have a non slip gripper to them because for the money, it seems ridiculous that you need to add on anything to make it practical/functional. Also, I wish that there was a different piece than the circular mat. There’s really no use for it, so it’s pretty much a waste of money.
