I bought this chair to help my mother when we went on a family cruise. It comes with a bag to carry it which is helpful. The chair opens easily and there a clips to lock it open. It rolls smoothly and turns easily. I had to roll it backwards when approaching doorways or flooring that had raised parts. Backwards keeps the wheels from catching which did not happen when going backwards. Once the bumps were navigated the chair easily turn around to go forward. We were able to move faster than my passengers walking near us. Getting the chair to lock for loading and unloading my mother was a challenge. I put the back of the chair up to wall so it wouldn't move. The biggest negative is the bar in the back of the chair which affects comfort. I brought a gel cushion so to cured this issue. The chair really saved the day since my mother can walk but very slowly which is not good on a large cruise ship. We would have missed meals without the speed and convenience of this chair.
