Question: The chair sits way too low to the ground for a normal size desk. How can you adjust that??
Document: The next day I ordered a 65cm ball to make up the difference. Once the new ball arrived, it was slightly too big and over the course of a few days it expanded to way too big. So I went back to the original ball. After 2 weeks of expansion and re-inflation, the original ball is now too big for my average size desk and I have since taken the height extenders off for the perfect size.
Bought this chair to use at  work. Have not been able to use it. The Ball is much smaller than pictured. Bought an electric pump & still cannot inflate to right size. I must now consider buying another ball... not too happy with that! We have had other exercise balls with no problem. The chair itself is also very low.
It rolls just fine on a low pile carpet and the brakes are no longer in my way.One note, the back support is plastic so it is meant solely as a relief support, not primary support. I do not recommend leaning on this for long term or even putting full weight on it as it was not designed for that use. If used as it is intended, with proper posture, it is a fantastic chair and helps greatly.
Wrong ball size came with the chair. It is very comfortable, but bad for my knees to bent and it does not sit high enough for my desk (even with the risers I bought separately.
At first, before purchasing I was worried that this chair would be too short for my desk and I would be sitting too low. Surprisingly It was almost too tall for my desk! It was a great height when pumped up. The casters on the chair are very cheap, it is hard to roll on carpet and i had to scoot if i moved the chair while sitting in it, which can be embarrassing when in a business atmosphere and almost tipping over.
When I bought it I def did not read the directions!! And was all ohhhhh nnnoooooo! The ball was super small when blown up! It just takes a day to air out a bit and stretch to size. I thought the plastic on the chair would be a little more durable, that parts kind of cheap but in all fairness it's a nice funky fun excersize chair to have when your slaving away at the desk.
The ball that they send with the chair is way to small. It's definitely not the ball they use in the pictures. It's so small it hardly stays in the chair! Very dissapointed. Luckily, I had a larger ball on hand, so I can still use the chair. Otherwise, I would've sent it back. Do
This chair is great and alleviates most of my back pain through the day. The only issue I've had is that the quality of the ball itself is a little on the low side. My ball has a hole after only 6 months of use. To help protect the ball I even have a throw blanket over it and it still did not last.Buy a higher quality ball and you will not be upset at purchasing this chair.
Ball deflates ever two days without a hole. The seat itself is VERY cheap plastic and creaks and bends. I am not a heavy person but the chair feels like it wants to give way on my weight.... much less a large person.This chair is not worth your time nor do I think ANY chair of this style would work.
When I saw the chair it looked great but once I sat on the chair I noticed my hips are not parallel to my knees. They're actually at a lower angle making a slope towards my body. I am not very tall, I stand about 5'4". I can't imagine anyone taller being able to sit in the chair. This chair would be perfect, if the balance ball was a larger size.
Answer: yes
