I called the helpline prior to buying this chair as it states that it has infinite positions and I wanted to confirm. I preferred the idea of that rather than being stuck at an angle that just wasn't right for me. The chair only has 3 positions and that's if you include when it is fully upright. You have to shift your weight back to get it to stay horizontal. If you have mobility issues I would say to avoid due to the reclining needing a strong push to move it. The chair is comfortable and supports my back but the issue is the reclining. Still trying to decide if I should return it as it certainly isn't infinite positions unless you sit forcing your weight back
