Gaiam Classic Balance Ball Chair – Ergonomic Stability Chair for Desk & Office | Yoga Ball Seat with Base, Air Pump, & Exercise Guide | Improves Posture & Core Strength (300 lb Capacity)

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.

UPDATE: Having sat on this ball every day for about 4 weeks now, here are my updated thoughts: 1) I don't miss sitting in an office chair. I'm keeping correct posture consistently and am now challenging myself to sit in correct posture in non-ball chairs. I don't miss the lack of arm rests either. 2) My back soreness went away after a few days. 3) I have to re-inflate the ball about once a week, as it loses about 2-3 inches of air each week. (I have my monitor angled up and notice my height go down in relation to the angle after about a week). 4) The nuts on one side of the horizontal metal ball bar that secures it to the base of the chair unscrew themselves. They have fallen off three times and I am now leaving them off since the other side is still securing the bar in. 5) I'm contemplating buying another one for my home to use at the dinner table or general lounging. ORIGINAL POSTING/FIRST IMPRESSIONS: Let me preface by stating I have really revved up my efforts to eat better and be more physically fit over the past 3 years. I know the importance of posture but LOVE to slouch. I am male, mid-thirties, 6'4", 200 lbs, reasonably fit, eat very well compared to SAD eaters, and consistently go to the gym 2-3 times per week. I work a sedentary job in HR and do not know why it's taken me this long to buy a product like this. It was delivered last night and I took it to the office and set it up this morning. Here are my first impressions after sitting on it all day. (Note the preposition use: you may sit IN a chair but you definitely sit ON this ball.) 1) Setup: very easy. Took less than 10 minutes including unpacking. No tools required, though a mini wrench is included. Everything was snap in or screw on. A hand pump was included with the ball and it took about 2 minutes to inflate. I purchased the Leg Extenders to adjust for my height and was glad I did. It takes the recommended height to 6'1'' but I sit at a relatively low desk anyway. 2) Function: I am sitting about the same height as my office chair. I kind of miss not having arm rests but I've been told by other ball chair users that I will get used to this and never want them again. I don't understand the importance of the back rest. If you sit upright like I've been doing all day, your back won't touch the back rest. You can lean back at the expense of bad posture - the rest will push against your lower to mid back. It is removable though and I'm contemplating removing it already, like other reviewers have suggested. 3) Posture: Sitting on this balance ball encourages better posture. It feels more correct to sit upright than to slouch. I can slouch still by slumping my chest and shoulders but it feels wrong on it, like I'm doing something I shouldn't be doing. 4) Feel: I don't doubt that I will be sore for a few days. I feel some soreness developing in my back due to sitting correctly and my shoulders due to having to hold my arms up off a rest all day. But just like with working out, soreness is your body's way of developing more muscle mass as it repairs strained and torn muscle groups. I feel confident that I will be way better off going forward. All in all, sitting still isn't the best thing you can do for your body. Our bodies were designed to move around, squat, jump, run, etc. But if you're in a job that requires sitting, wouldn't you want to do everything you can to make sure you're at least sitting in the healthiest way possible? I know I sure would.

I wish I had purchased this sooner. It is so comfortable and forces a better posture. I don't feel like I need to get up after sitting for 15 or 30 minutes, even though I should. The only down side is that is does need to be pumped up every so often but that's to be expected. The exercise sheet it comes with is great but some of the exercises shown are awkward to do with the chair back on, as shown. It takes less room than my other office chair as it can tuck in a bit better and has a smaller footprint.

I love the chair. The only issue I have is with the quality of the ball. The ball does not compare to other exercise balls out there. But, I use this as a desk chair and for that, it's perfect. Stronger back, better posture, simple design. I don't know why we don't have more of these in offices....especially with everyone having back issues.

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

Ottimo prodotto, facile da montare, rifinito nei dettagli, molto utile il blocco/sblocco delle ruote e in ufficio da un certo stile

I purposely too my time to review this product, I wanted a Ball Chair for 3-4 years but could not afford it until I saw it dropped to under $90. I jumped on this deal so fast! I have suffered from lower back pain for 15 years as I have worked a desk job since 1999. I picked up a kneeling chair for work and this Ball Chair for my office at home, within two weeks my back pain was mostly gone! 15 years of back pain and all it took was better office chairs, wow! Assembly was unbelievably easy but after trying to inflate the ball for 10 minutes, my arm got tired so I grabbed my electric air mattress pump but it still took 15 minutes to inflate. Let me tell you, this is the most comfortable chair to sit on! It took a couple days to get used to the low back support but I couldn't be happier.
