Bests & Worsts Reviews from Amazon

I searched long and hard for a chair to use at my art work station. The max seat height from the floor is 35" the min is 29". The max height for your legs to hit the bar/ring is 23" min is 17". The seat width is 15.5" and padding is about 4". I didn't have the back on for the last few months that I had it because we put it together wrong, we fixed it last week and added the back, but I'm not sure I like it on there because it reduces the area of the sitting area if you have a larger bum. Not sure what the max weight is, but I'm a bit over 300# and it works fine for me, I'm also tall (5'9) so reaching the bar isn't a problem. When it's at it's tallest it is a challenge to get in and out as many reviewers stated, my man is constantly worried I'm going to fall and break something when he watches me get on it. I secure the rolly feet against a wall and then hop up and get comphy before rolling over to my work station. LOL There are NO LOCKS on the wheels. I typically will sit in it for increments of 1-2 hours and then take a break. I'm an artist so I need to stretch and move around a bit to get kinks out. However even doing that after around 4-5 hours of sitting in it with breaks I get lower back pain.. that may be because of the type of work I do and how my body is positioned (hunched over for detail work). That's why I added the back to it to try to alleviate that problem.. but that hasn't worked well. I have also gotten pain mid thigh from sitting on it for several hours at a time because of where the chair hits your legs depending on your height. It's a great chair for the price however if you have a larger bum I would suggest getting one that has a larger base. I researched ALOT and didn't want to pay out the nose for a chair and needed one that went that tall for my work station, which is very hard to find without paying over $300.
