Gaiam Classic Balance Ball Chair – Exercise Stability Yoga Ball Premium Ergonomic Chair for Home and Office Desk with Air Pump, Exercise Guide and Satisfaction Guarantee

I love this chair but takes some getting used to. Not the most comfortable for sitting for long periods but I guess that must be the point to get up and walk around and not sit for too long.

Muy cómodo y funcional ,ideal para el puesto de trabajo

Très bien installé. Roule très bien exactement ce que je recherchais. Toujours en état depuis l'achat l'an dernier. Confortable et résistant

La compre por menos de 100 euros y la verdad que es una silla fantástica. Hay mucha gente que usa los balones de fitness sin ruedas, pero el problema esta, que para moverla, y colocarla en la posicion correcta (y no deformar la pelota) es molesto. Ademas trae un agarrador para moverla con mas comodidad (no es un respaldo lo que aparece atras). Creo que de las sillas que he encontrado tanto en almacenes como en Amazon es la mejor relación calidad precio

Fabulous chair. Great for core stability and reducing back pain

I've borrowed my co workers Gaiam Balance Ball Chair when she's been out of the office. I just loved it immediately, less back paid, less pressure on my legs and helped with my posture. I just had to get one for myself. It arrived today!!! Like a kid on Christmas I tossed my old uncomfortable office chair to the side and immediately put this together. I like the pop of color the green has....so that's about all the positives I can give. Assemble of the chair was very quick and simple. Inflating the ball however, with that ridiculous pump thing, I had to go into a conference room to put air in it. (just not appropriate to do while sitting at your office desk) The ball.....the ball is inflated to the max I didn't want to pop it. I placed it in the chair and it was like dropping a beach ball into it. This ball is SOOOOOO freaking small when I sat on it I could just about sit Indian Style on the floor!! I'm 5'10 about 150lbs. I immediately rolled it to the side and grabbed my neighbors ball and I'm sitting here typing this review in comfort. UPDATE 6/9/15: okay so I called Gaiam customer service about replacing the ball and was told to just give it a couple days to expand to it's full size. So today (day two) I came in and inflated more.....to my SURPRISE it's not perfect IT"S BETTER. I'm high yet still able to lean back on the back rest comfortably. This goes from 2 stars to 5 in my book. I couldn't believe it. If you think its to small on the initial opening let it sit in a warm space over night and then add more air......you'll be pleasantly surprised. Everyone at work is taking triple looks at my comfy, supportive, fun colored, new office chair! Love it. They should put a disclaimer in the description so people know what to expect. would have been helpful for me. Considering it? Go for it!!! Since I had it shipped to the office I don't know if I should return all of it or go in search of an adult sized ball. I did some digging and I see there are different sized balls on Amazon sold separately for 19.99. Seriously?! How do I just exchange the ball?! Hello, AMAZON? Anyone out there? I've spent allot of money on this site at least deliver the items pictured. The lady in the picture isn't squatting on the floor she's at desk level.
