Trideer Ball Chair: Perfect for Yoga, Exercise, and Stability Training

Amazon Customer: The ball itself was great, the ball doesn't fit in the donut thing, to big. Does keep the ball from moving around, although I find it easier to use without it.

Cheryl L.: Ball great. Takes time to inflate. Stabilizer ring tends to deflate every week.

Limbo: I am currently using this product as I write the review! So you know its good. It helps prevent back pain as I work from home and also allows me to feel activated throughout my work day. I use it as a dual function for my workouts too! I do wish it did not deflate so quickly, I have to repumup it every 2 weeks or so. Other than that it is great and I will be using it for years.

GenevieveGenevieve: Overall, great quality and really comfortable! I love the ring that comes with it and it actually adds some great stability. If I had ONE negative thing to say, it would be that pumping it up in office is a little embarrassing especially with the little foot pump they give you and trying to get the plastic plug in is a bit tricky. I expected both of those, though and the actual product is amazing!

TiffanyTiffany: I pulled it out of the box and gave the included little hand pump a try. Holy cow. That was a workout! Both arms were tired and if you stop, the air back- flows. No thanks. I'll save that for inflating balloons.
I broke out an air compressor and filled the ball until it looked taught, but not over-filled. I let it sit overnight. The next day I gave it a sit and felt entirely too low to the ground. I put a little more air in it, but was worried about how much air it could take. I have it another sit and it felt much better... so I worked a full day on it. I had to keep reminding myself to straighten up my back. It takes some getting used to. You certainly can't whirl around to see behind you, like you would in a typical office chair... so when I heard my dog outside the door, I had to twist and crane my neck. LOL. After a day on it I decided it still felt a little low for me. I'm 5'6" tall, with a 28.5" desk, so I got the Large 65cm ball as suggested. I broke down and grabbed the instructions, to make sure I didn't over-inflate it. I measured from the floor, up the wall 65cm, made a pencil mark, then took a straight edge and held it out... I definitely had more room to go to...

MSD: Sit on it daily. It does encourage you to slouch to focus on not slouching.

Claire Watson: I use this as a seat at my desk. It has caused me to sit correctly, plus it is just SO easy to exercise your hips and core whilst working. I am sure it can be used for many other exercises, but haven’t discovered them yet. Wouldn’t be without it!

mf: Der Ball wird mit einer Pumpe geliefert - man muss zwar erst rausfinden, welches der beiden Pumpenenden hier Luft saugt und welche bläst, aber das hat man schnell rausgefunden. Der Ball hält die Luft sehr gut drin und der Standring ist ideal für die Aufbewahrung. Rundum: Klasse Gymnastikball.

Amazon KundeAmazon Kunde: Der Ball hat unschöne Falten. Er ist seit Donnerstag aufgepumpt und würde nochmal nachgefüllt. Aber die Falten gehen nicht weg. Der Äquator ist weder Beim Ball als auch bei dem Ring nicht schön verarbeitet. Widerstandsbänder wurden keine mitgeliefert.
