I purchased this bath chair after fracturing my left leg. I needed a sturdy bench to help me get the leg in and out of the tub and to sit on during the shower. I'm a fairly fit, 40 year old man.
My only complaint is that the chair does not "lock" into the open position. With many tubs slanting slightly towards the drain, the chair tends to fold up a bit when a person leans forward (say to adjust the shower or reach for the shampoo). I could see this being dangerous for an elderly person or anyone who was not paying attention.
Otherwise, this product is well built, easy to fold up, light, and does the job. Great value for the price.
