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 used this product for the past 3 days, using it everywhere but the kitchen and bathroom for sitting. I noticed an improvement in my posture and an alleviation in pain from my lower back. As much as I bounce, me legs will have huge muscles. lol. It took less than 3 minutes to inflate the ball with the provided hand pump. The metal bar, part I, is very difficult to put in for whatever reason- one side goes in fully, the other doesn’t. So I pulled them out and put the problem side in first, and now the previously good side isn’t going in 😒 It didn’t stop the functionality of the product so I’m just ignoring it for now. lol. All in all, great product! I’ll probably order another one so I can have one for each level of my home.Also, it’s very lightweight! Maybe less than 10lbs. Super easy to transport.

I love this product so far. I read a lot of reviews about the pump not working, but I got it to pump to the full size without having to wait 24 hours, though it requires some strength. Finished building and pumping in 5 min. At first, the pump did leak air, but then I twisted it more closed where I heard the air leaking and it immediately stopped. Just got to play with it a little. Then I just kept going until I couldn't anymore. I'm fairly strong as a woman though so I was able to push past that barrier point when getting it to full size right away once the pump was fixed, without even meaning to. It was quite the arm workout 😁 I would say my biggest complaint with the pump was the pipe piece wouldn't fit all the way into the opening of the ball. It was more like I laid it on top the hole and kept still as much as possible while pumping it. Other than that, I still got it to full size without having to switch to another pump in the house like Ive read others doing. I love it. I got it to replace my gaming chair since the suspension and arms broke and is no longer adjustable to my height and is very uncomfortable, causing pain to my legs and back. I know this isn't a gaming chair, but it's cheaper and serves dual purpose to do yoga and pilates with too, while still being comfortable. Moment I first sat on it I popped my back, plus love the mobility of it. Highly recommend.

Shorter than expected

Chair works great! Very comfortable. Was helpful to use a rubber hammer to assemble the pieces. Assembly took about 5 minutes.Read the instructions on how to properly inflate the ball, to reach full inflation/size. I attached an image showing the instructions to this review.From reading others reviews about the exercise ball being too small, I don't think they followed the instructions properly. It's a solid chair. Just follow the instructions and you'll be set!

The package arrived with no pump in it. Also there is no air stopper in the box. it does not keeping the air inside!

As many people here noted, manual pump enclosed is completely useless so no surprise here. Just want to confirm this. Useless as last year's snow. I tried it out of curiosity and then set it aside. Used an electric pump for mattresses etc. Once inflated the ball is OK. I inflated it to 19.5 inches that is slightly smaller than recommended 52 cm. Still fits and feels OK.

The product arrived in a timely manner and was simple to put together. I was pregnant and working a desk job at the time I purchased this product. My back had been killing me from sitting all the time. This product changed that entirely. It is comfortable and so much better on your back. I would reccomend. Also the colors are as pictured. This is great alternative office chair seating.

I think the grey color is beautiful. It is great quality. Kids love it a lot.
