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

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.

Gives that bit of height needed to make the chair work more ergonomically with a desk.

It's rare to find extenders for my balance ball chair, I'm glad that I've found it on Amazon with reasonable price, it works well.

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.

Je l'ai acheté en complément de ma chaise-ballon pour mon travail au bureau. J'ai réglé mon problème de douleur au dos et grandement amélioré mon confort au niveau de la circulation sanguine dans les cuisses. La hauteur en position assise avec ces rallonges est idéale pour moi.
