This chair is more on the expensive side, but it is more comfortable than trying to sit on an exercise ball without the base. I use this as a desk chair while working from my home office. It is solid and sturdy. So far I love it and it has saved my back.

Me parece que es una buena opción si pasas mucho tiempo sentado y quieres cambiar de posición o descansar cada tanto. No es una silla en la que puedas estar 5-6 horas pero si la usas 15-20 minutos cada par de horas sentirás la relajación

Gaiam Ultimate Balance Ball Chair purchased July 2020, ... used at work, love using it for seating at my desk, ... and on 04/17/2024 one of the supporting legs with a wheel just SNAPPED :(

As I approach my 50's I don't want to turn into a hunchback - working out helps but I noticed I am slumping more due to sitting and working all day. Really wanted a chair to help with my posture, lower back and neck pain, and I purchased this after reading the reviews.Setup wasn't too bad - the instructions are printed very small (even the pictures, and yes I was wearing my glasses), and some of the written instructions made me chuckle ("press hard with hammer", for example, that still makes me laugh). Biggest issue with the installation was putting the small plate on the bottom of the wheel base - when putting the wheel base onto the main chair, it won't insert all the way (not even with my full body weight on it, nor "pressing hard with hammer" lol), so I just had to leave it most of the way inserted, and toss the little plate and screw to cover the bottom hole.I am surprised at how much I like sitting on this chair - it's very sturdy, surprisingly so, seems well made, and way more comfortable than my desk chair. So far, it's helping me to sit straighter for longer. I also don't catch myself slumping over into the hunchback position - so far so good! I have very high hopes for this chair long-term.

アマゾンで２回注文しましたが、２回とも途中で商品が用意できないという理由で、キャンセルされました。(それぞれ違う業者です)残念。実物を見たことがなく、使い心地は分からないです。職場でジェリーフィッシュのバランスボール椅子を使っているのでこちらも期待しています。(腰痛対策に)いつかちゃんと購入できたときには、またリビューしたいと思います。期待を込めて★３つ

Venía de usar una silla sin respaldo por años, muy feliz mi espalda, no muy felices mis rodillas. Había intentado la bola por sí sola y la altura no era la correcta. Esta silla es justo lo que promete y mi espalda y rodillas lo agradecen.

Love it and it was super easy to assemble. Did it myself in less than 1/2 hour with no parts left over!

The product is wonderful, allows to move while remaining at the right place. I use it both at home and at work. Less hips and leg pain when getting up after an hour or more sitting down.

I bought this because I'm spending a lot of time at my workbench height desk, and needed something that was more comfortable than my regular stools. I'm a heavier user, which factors in.-First problem solved: The back was wayyyyy too far forward. I couldn't center myself on the top of the ball, and the metal tubes run into the plastic webbing in the undercarriage. I used a pipe-cutter to shorten the tubes by about 4" or so, then I could sit on top of the ball.-Second problem solved: The cutout in the front of the frame allows the ball to squoosh forwards. Because it's on wheels, you can't really push it back, or it shoots out, and then you're on your butt. And the ability of the ball to deform out the front, just makes it a weird experience, because I felt like I was always fighting with the chair to get it to feel good. If you look at their earlier models, this is clearly a problem they had to deal with before, which they solved with a metal arch that holds the front of the ball in. Well, I didn't want to go to that length, so I used a nylon ratchet strap, hooked around the metal bars, basically 45 degrees up from below the back, up over the front, and back again. Now the ball is constrained, and I can sit up straight, which is what I wanted this damn thing for in the first place. The strap keeps the front contained, and I can sit happily while I work.And this is why this is such a complicated review. What I've come to is that it's possible for this to be a functional, comfortable chair. Very much so. I used to be a muscular guy, now I'm middle aged, and I need a chair that allows me to sit comfortably. And after being modified, this chair works quite well. And I'm pretty happy with it now.But I'm also aware that my skill set isn't typical, so I can't recommend this thing for what I consider to be an average person, because it basically requires some real modification to make it do what it was intended to do.It's a shame, really. I like the idea of a yoga ball for a chair. But most of the reviews I read about the chairs from this company in particular is that they can't design a decent chair.---Update: A month or two later.One of the screws fell out of the metal plate that bolts the wheeled base to the plastic frame that holds the ball, and the metal plate has bent. It's a chair that will see a lot of wiggling and wobbling, by design. They should have either included better lock washers, or added some loctite to the recipe.10 minutes later, I found another screw to replace the one that's gone missing, and re-worked the ratchet strap that's constraining the ball into a supportive position. All I can think is that their stated weight limit of 300 pounds is not really accurate. Not in the long-term, anyway. Especially given all of the other recent reviews of broken bases, etc.It takes a lot to get me off my butt to review something. But this thing has filled me with enough spite and petty snarkiness to make a suburban teenage white girl blush. So I hope whoever designed this godawful garbage gets some serious karmic payback.

I LOVE this unusual-looking chair, the Ultimate Balance Ball Chair. I received it 4 days ago, a little over a week from the date I ordered it. I was pleased from the minute I got it; it comes with an assembly instruction sheet that is very EASY to follow, I did not need any tools to put it together and it only took me about 25 min to assemble the structure of the chair (which is very sturdy); though it is hard to tell from looking at this product on a computer screen, the larger parts as well as the smaller components are all very well-made. The only thing you will need is a small air compressor or a bicycle air pump to inflate the Balance Ball.The amazing thing about this Ultimate Balance Ball Chair is that I could feel it relieving stress on my spine almost immediately! For years I would suffer with lower back pain whenever I had to sit at my desk for long periods. The dynamic ergonomic design of this chair forces me to sit straight, which immediately improved my sitting posture. And in order to keep myself sitting straight I find that I am using and strengthening my core muscles, which has resulted in a 75% reduction in lower back pain. The Ultimate Balance Ball Chair is not only comfortable but it also provides ergonomic back support.As an additional bonus, I was surprised to find the Balance Ball chair comes with a full color, illustrated Exercise Guide poster with 9 different strengthening exercises and stretching routines. I'm actually sitting in my Ultimate Balance Ball Chair as I write this review and I am still amazed at how comfortable this chair is!
