610-6002RTL Balance Ball Chair - Classic Yoga Ball Chair with 52cm Stability Ball, Pump & Exercise Guide for Home or Office, Black

Absolutely stellar product. Such a well designed chair. I'm a 28 year old, 6ft 1in, 225lb man & this thing is insanely comfortable. The back rest is so well placed & offers just enough support to rest your core periodically, the ball is stable & comfortable, the base of the chair was easy to assemble (took all of 10 minutes), & this is truly an almost perfect product in every way. If you have trouble sitting still, if you want to be more engaged while working, if you don't want to cut off the blood circulation to your legs for 8 hours a day, then just buy this thing already haha. I did see others mention that the roller wheels don't do super well on carpet, and that is true. My office floor is carpet tile on concrete & even then, the wheels aren't phenomenal. Specifically when I'm sitting on the chair trying to roll, I can make it happen, but it's not necessarily easy. But, don't let that deter you from purchasing this otherwise wonderful product. Can't believe how nice this is for the amount I paid.

Great office chair. I bought a second one for the office. My original one is 6 years old now and has no issues. Beats any gaming chairs I tried and I haven’t had back pain from sitting in years. Super easy to assemble. Bought it for the price and kept it for the value.

Great chair, functional and helpful in improving posture if at your desk all day. Good support, easy to use and construct. The ball is small and I would recommend purchasing a bigger ball to help with stability.

You should be aware that this chair won’t be for everybody. If I didn’t have back and hip issues, I wouldn’t have this for my office chair — and as it is, I use it as my “break” chair and I use it when my pain is really bad — BECAUSE this chair really helps with my low back and hip pain. I didn’t think it would when I bought it, but I was really hopeful. And I was surprised when it did. I had to take the wheels off the bottom of the chair so that it was the proper height for me, and that makes it more difficult to move around, but it also makes it less likely to slip out from under me when I go to sit, and it’s not a very heavy chair, so moving it without the wheels is still easy. One of the things that I think really helps me with my back is that sitting on this ball seems to help stack my vertebrae correctly. It forces me to have the correct posture, which actually helps to alleviate my pain, and I can feel my core muscles activating as I sit because it’s a gazillion little movements throughout the day, and those core muscles are super important in maintaining your spine health. So — if I didn’t have back and hip issues, I wouldn’t have this chair (because it doesn’t allow you to slouch 😊), but because I do have issues — and because it really works to ease my pain — I’m delighted with it.

I’ve wanted a balance ball chair ever since I read a few articles praising them on Lifehacker. I already owned a cheap balance-ball, but had no base or way to really stabilize the ball. After reading endless reviews and going through the questions/answers here on Amazon, I finally decided to bite the bullet and order the Gaiam Balance Ball Chair. In the box is one chair frame (disassembled), one 52cm balance ball (deflated), a hand pump (borderline useless) and a nice, well-illustrated booklet containing exercises/stretches to use with the chair. The chair itself is a cinch to assemble – the casters simply press into the base, then the back support clicks into the base and is held in place with 2 twist-in bolts. Finally, 4 small nuts hold on the wire ball support (a little wrench is provided). All in all, assembly takes under 5 minutes. The ball is a different story – the ball needs to be at room temperature before inflating. You only want to inflate the ball about 80%, then let it acclimate and stretch for about 24 hours. Gaiam provides a small hand pump, but it’s incredibly tedious an inefficient to use. I used a bicycle pump and inflated the ball to about 42 cm (about 16.5”), then left it sitting for 24 hours. Note: By 42cm, I don’t mean the circumference of the ball. I marked off 42cm from the wall, placed the ball against the wall, and inflated until the edge of the ball touched the 42cm mark on my tape measure. After acclimating, I followed Gaiam’s directions and inflated the ball fully to 52cm (about 20.5”). The ball, being fully inflated, needed some manipulating to fit into the chair frame, but nothing too difficult. Before I purchased the ball chair, my main concern about the chair was height – I am only 5’0” tall, and was afraid that the chair would leave me sitting too low. Turns out, the opposite was true – once the fully-inflated ball was in place, I was seated up very high, and my feet did not touch the floor. Gaiam’s instructions say to inflate the ball so that the thighs and shins should be at a 90° angle to the floor. If your hips are higher than your knees, deflate the ball. Conversely, if your hips are lower than your knees, you need to inflate the ball to find that ‘sweet spot’ for your height. I ended up deflating the ball until my feet were able to touch the floor – as a result, the ball was not as firm and had more ‘give’ to it, but the ball is still quite comfortable. I have to make slight adjustments to keep myself stabilized, which activates my core. I also have to sit up straighter instead of slouching or leaning forward (as us shorter people are prone to doing). The chair’s ‘back’ isn’t really meant as a support structure; per Gaiam’s instruction booklet, it’s strictly for stability during exercises. Work your way up to using a balance ball chair – I recommend ditching your office chair and going to the balance ball chair full-time. As you become more conscious of your posture and core, you’ll be utilizing muscles previously neglected. So, work your way up to the chair – I spent a few hours in the ball chair, then a few hours in my regular office chair until I felt comfortable going ‘full-time’ with the ball chair. I do not use the ball itself for any exercises, though I do perform some of the seated stretches from the included booklet. Now, my posture is so much better, my lower-back pain is near nonexistent, and I can definitely feel a difference in how my core feels. I also don’t experience the tailbone pain that I used to have after a long day of work. For under $80, you won’t find a better chair.

Le encanto a mi sobrino... tal cual la foto

Muy cómodo y funcional ,ideal para el puesto de trabajo

Love, love, love this chair. Helps me with my posture and lower back pain when sat too long at a desk. Can’t recommend this item more. My hip pain and lower back pain is gone just like my massage therapist recommended. Easy to assemble. It comes with instructions as well as an exercise sheet to do with the seat. It feels solid and well crafted. The height of the seat works great for me without extenders (I’m 5.5 feet or 167cm). This model has the option to add extensions for taller people which is great. I inflated the ball in several steps as recommended and worked great. Couldn’t be happier with it.

Ball size definitely not 52cm. With a lot of effort, only able to get ball to inflate to 49cm

Love this. Easy to assemble and great for posture and movement
