Very sturdy! I use it to help my shorter clients get up on my padded lash extension lounge chair —for them to lay down for their service. This step stool helps them feel secure. It doesn’t wobble or lift when you put pressure on the handle. Excellent! One of my clients has had an operation on her foot. She used the stool to carefully get on and off the lash bed. It works like a charm and tucks under the bed easily. I have recommended this step stool to several clients and shared the link.
