GaiamClassic Balance Ball Chair Leg Extenders (Only Compatible with Classic Chair & Classic Backless Chair)

This works perfectly on my regular office chair! Raised my height exactly where I needed to sit comfortably. I had to order 2 sets because I needed 5 for my chair.

I wish the chair would just charge a few bucks more, and come with these.FYI: You cannot use the Gaiam ball Chair without these if you plan to use it at a desk or even table for work!!!!!!!!! I am an average height of 5'5" and sit at a regular desk and table for work in office and at home - and was forced to spend the money for both sets for both chairs just to have them be suitable for the use the chairs are intended for.They serve the purpose, but for an additional $15, it seems to be just a money maker for the company. I had no choice but to buy them for my chair at work, and for my chair at home now... so spending $30 JUST to make the chair workable for the purpose it was meant for bothers me.They are easy to install, and work properly (expect on both sets, the BRAKES seem to enact on their own ALL the time, and it makes me crazy to hear the brake noise and not be able to move). So it seems, the lever for the brakes is not secure and moves easily on its own. So be cautious of that if you have to roll around or slide back and forth at your desk.

Made the chair even better by raising it up to a more comfortable level.

Easy to attach, added additional height. I think I could do with another inch of height but otherwise it added what I needed to be comfortable (I’m 5’11”).

These have made my yoga ball chair usable. The marketing information says these will help short people use the yoga ball chair, but in my experience they are necessary to use it at all, and I'm 5'7" (not short). I bought the yoga ball chair and waited too long to try it out. By the time I found out it was too low to use with my desk, it was past the time I could return it. I was going to sell it or give it away or see if a larger yoga ball might solve the problem. When I was shopping for the larger ball, I came across these leg extenders so I bought them. Now the ball puts me at just the right height to work at my desk. My back feels much better from using this for working at my desk, but I have noticed that the nerves in my butt tend to get tingly when I've been sitting for a while (like the "going to sleep" feeling you get in your arm when you fall asleep on it), and this never happened when I was using my piano bench to work at my desk. It's not a big deal, and it can actually remind me to get up and walk around, but it's a little weird. Anyway, I'm just glad I'm able to use the yoga ball chair at all with these extenders.

These bring the chair to the height it should be for desk work. Maybe should just include these or make the chair higher?

Purchased the Gaiam kids balance chair, but it was too short for my son to comfortably use at his desk. All the reviews say this is not compatible with the kids balance chair, but it was a perfect fit. Even the Gaiam website I saw a question someone asked if these would work and the answer was no. Decided to get these anyways as it was only about $11 and figured if it didn't work I could modify these adapters or the chair to make it work. Upon receiving the leg extenders I was pleasantly surprised to see that these were a perfect fit and I had all four on in less than 5 minutes. So I have no clue why all the reviews say it's not compatible. There are some other brands that look very similar, but were actually more expensive than these and since we bought a Gaiam chair, figured I'd stick with the Gaim extenders in hopes they'd fit...and they did!!

Made my ball chair the right height for me. Takes a bit of force to get the caster pegs into it. Go easy on it.

Definitivamente es necesario comprar estos aumentos para la silla, funcionan perfecto y súper fáciles de ensamblar sin mayor problema.Mi único tema es que no entiendo porqué vender estos como complemento adicional si la verdad es que la silla debió de haber sido siempre de cuando menos esá altura ya con los aumentos, ya que de lo contarario sería más como altura de silla infantil y no le veo sentido pagar por algo que debió ser parte del diseño original de la silla y solo si se quisiera algo más alto por temas de restiradores o mesas alto de diseño pero fuera de eso la silla es de altura impráctica sin los aumentos.Fuera de todo lo anterior la silla increíble y los aumentos se integran sin mayor problema.

The ball chair I ordered for myself (severe arthritis in hips) : after researching extensively proper weight and height, was such a tremendous disappointment. The parameters need to be perused because I ordered the correct size for my weight/height but was sitting lower than work station. Thank goodness for Amazon for carrying the extenders. Easy to install and results: 100% work satisfaction!

These seemed expensive at first, but after receiving them I realized the build quality was very high so the price was justified in my opinion. I've been using them for three months and have had no stability or any other issues at all. Recommended.

I bought these hoping they would fit my ball chair but wasn't the same brand as the extenders. I knew that when I bought them but Amazon sorta made it sound like they'd fit other brands. So I had to return them BUT they wouldn't accept my return but they did refund my money. So I guess if you are going to get the extenders, make sure you have the same brand of ball chair to match the extenders.

The fit into the base is excellent and well engineered. I expected the increased height to be greater than it turned out to be. With my luck they will come out with THAT product next and I will kick myself for having spent more than I should have for something that is less than I had hoped.
