No tools needed, just a lot of strength! Very tight tubes need straightened and twisted on. Somewhat wobbly, but will give it a chance at my mom’s house on carpet.
This is the perfect little stool to boost my dad up into his pickup truck. However, I have ordered 3 of them because I keep running them over and forgetting them in the driveway. He can't live without it and they are not that expensive.
Great little step stool which is also ADJUSTABLE! Sometimes around home I need just a little more height to be comfortable when reaching. Now all I have to do is remember I'm on the stool before stepping away from it...
