Review on Foldable Multi Tier Pet Storage Stepper - 20''X11''X12.5''(2T) / 27.5''X12''X15' (3T), Holds Up To 15Lbs Small & Medium Size Dogs, Grey (3T), Solid - Woolly Pet In Style by Dube Jansen

I got the 2 tier stairs and I love them! A few people mentioned them not being very sturdy for dogs, but I have to say that my senior kitty (10 lbs) and also my crazy 21 lb toddler both like to climb them. Maybe other reviewers did not assemble them correctly. They are not very tall and I almost returned them for the 3 tier but I like how they don’t take up much space which is important so I decided to tuck them behind the night stand and it works perfect! She can climb up to the night stand and the bed from there. I also love that they are collapsible, you can store items inside and they are easy to assemble. Would buy again!
