It took a bit of coaxing with treats to get my dog up and down them the first few times but now she just runs up and down to get onto my bed without any hesitation. It's well put together and I have zero problems with it. My dog also seems to love the fact she can use it to get up without hurting herself. 10/10 recommend for anyone with a very high bed that doesn't want to injure their furbaby! Four steps is good for very high beds like mine, so if you have a bed that is kind of high but not super high, then I recommend one with three steps to do the trick. But this four step one does the job for very high beds like mine!
