So convenient!


I love the convenience of throwing my leg over the stool and sitting rather than pulling out my chair to sit and then readjusting it for comfort. Plus, the gentle sway of the stool to stay balanced just feels good.More > < Less

Love it. It’s the perfect height and incredibly comfortable..


Most popular with the kids


I put this one in the upper grades resource room, and the kids immediately started squabbling over who got to use it. The teacher eventually had to put it away, and make the kids earn it back by doing their work, or he could get nothing done. I did find out that I could pump it up with a bicycle tire needle pump, as some of the adult sized kids can sink it a bit and it required some filling to reinflate it. The New York office of ErgoErgo were very helpful and got right back to me to answer my questions about it. Nice support for this.More > < Less


Feels Great


When I first received the stool it was too tall I am only 5'2" so my legs were too short.I kept reading the reviews and I found one that said their son adjusted it for his size. So I did the same thing I let some of the air out and I no longer have to use a small stool so I could stay on the stool. It is very comfortable now.More > < Less




I like using this stool. I bought it to use at my computer, but I have hauled it all over the house to use with various jobs. I have even used it outside for work when I was tired of bending over. It is lightweight and my grandkids like it a lot too.More > < Less

About ErgoErgo

Active Sitting

This Made in the USA ergonomic stool keeps you active while sitting. It’s shaped like an accordion to encourage small movements, use your muscles, and reduce slouching.

By staying active, you boost your strength and flexibility. ErgoErgo challenges you to stay in an alert, upright position that helps your circulation, your breathing, and even your focus.

Traditional chairs give your core and back muscles a lot of support, which is why you tend to slouch. That causes the muscles to weaken and creates discomfort in your shoulders, neck, and back. With ErgoErgo, you’re shifting through a range of small movements as you sit, strengthening, your body. And unlike traditional stability balls, this stool won’t roll away when you get up.

It’s a more active, healthier, cool-looking way to spend your time sitting down.
