Too Small

from Wayland, MA – Verified Buyer– Top 100 Reviewer

I got this to use at work to improve my posture. The ball that comes with this was way too small -- when I sat at it at my desk my desk came just below shoulder level. I swapped out the ball with a bigger one and it works well now, but I wouldn't recommend use it for work with the ball included. The casters lock so you can keep it in position. My only other comment is that dismount can be tricky because without locking the wheels they are very mobile -- when I stand up the whole thing shoots out from underneath me if I'm not careful.
