Therabuilt Adjustable Pneumatic Stool - Black Ergonomic Stool for Massage Tables, Exam Tables & Medical Offices - Comfortable & Durable Healthcare Seating for Chiropractors, Therapists & Physicians

Easy!I bought this for my business. Super comfortable with the thick cushion, and rolls easily as well!One draw back using this is over-reaching when seated on it. I did this and landed on our tile floor and could have hurt myself worse than I did if I had something hot in my hands at the time. The stool shot out behind me and I really landed hard. The other drawback is slipping on the seat if you are not centered properly. I plan on attaching a pull strap underneath so I can pull the stool under me to sit onto the middle of the seat. Otherwise you tend to sit on the edge and this can be dangerous. I use it quite a bit in the kitchen while preparing meals and baking. Having severe arthritis I needed something that helped me eliminate getting up and down a lot. I think brakes would be useful if you remember to disengage them every time you wanted to move. This could be a hassle and prove to negate the usefulness.I love these because they move easily and help me to sit up more straight. I tend to hunch or get to much pressure in my low back with office chairs. This is the only office seat I use.I will also say, I think one of these helped save my life!!! I was transporting my seat in my car—passenger front seat. I was hit head-on by a drunk driver that evening at 70mph, and my dashboard could not collapse into my legs because the stool held it in place! THAT is sturdy!!! Yes, it lost a wheel or two, but all things consideredd, it was a lifesaver!!! So A+ on durability!!! This is my second one.I got this because I have arthritis and can't stand for long periods of time. Wheels around very nicely. I love the height range goes low enough i can pick up stuff off the floor easily, and high enough i can reach into my sink :) and my kitchen counters. I was worried about slipping off, because seat is a very slippery vinyl. So I got some upholstery fabric and a staple gun and recovered it, problem solved great no more slipping on the seat I also added a pull strap to help pull it under me. It helps to get the seat centered properly, seat is very thick so you tend to sit on the edge if you don't make sure your centered.It came sooner than expected, requires NO instructions to put together, and just the right size. I have a really low desk and had to carefully consider chairs that would sit low enough. This one is perfect and comfortable!I bought one stool, then two more after the first one worked out so well. I use it in my music studio for guitarists and other seated musicians. The cushion is very plush with just the right amount of resistance. The controls are easy to operate. The caster perform adequately enough especially given the circumstances of instrument cabling on the floor that needs to sometimes be rolled over. All in all I am pleased with stools and would recommend them in just about any environment where long term seating is needed.This is a well designed and manufactured stool I use in several different ways. When I work with a guest on one of my office computers, I have the guest use my big, well padded computer chair while I sit to one side on the stool. It has thick padding under a neat cover, height adjustment and five rollers to allow me to scoot around and shove it under my desk to gain more room when a guest leaves. When I'm working alone on a project that generates piles of stuff to keep track of, I pull the stool out from under my desk and use it as an auxiliary table.
