Hokki Stool, Flexible Ergonomic Seating Stool for Kids and Adults, 20" Seat Height, Black

I have used the Hokki stool in my middle school classroom for a year and it is a hot commodity. Even students without attention issues love to sit on it. I ordered two more so that I have a total of three for my classroom. A little pricey so I wrote a classroom grant.

I prefer the Hokki stool to a ball. The seat is a little hard, but I think it might be like riding a bike and I'll soon get used to it. Or I can just make a little cushion for it.

Very durable. Very light. My daughter has one in her classroom and I purchased it right from my phone while at the class Christmas party. It's a great stool.

Product too low for adult. Does not adjust. Easily slips over on hard wood floor.Seller has returns shipped at owners expense. That's not clearly disclosed anywhere in product details

I'm using this stool in my massage therapy practice. I like that it's lightweight and sleek, making it easy to move around the table during treatments, and it doesn't take up much space in my treatment room. I also like the unstable design very much. What I don't like: the 20-inch stool is actually 20.25 inches tall. If I would've known this I would've ordered the 18-inch version. The stool I received also has a couple imperfections. One of the scalloped ridges around the hard plastic edge of the seat looks like it was melted or scraped - it has sharp edges. (Perhaps this is a production flaw where the plastic was separated from the mold?) Also, the very top - the actual seat - is a gray, foam-like round sticker. That would be fine except that the sticker was applied so that a bubble remains in the center, and it often makes noise as the adhesive comes into and out of contact with the hard plastic surface below. Considering the price, I expected better quality control.

Great stool. Help's the kids concentrate. As wierd as that might sound, a wobble chair. But it does wok. Plus it's dufferent, a novelty.

I ordered 2 of these stools for my active middle school students. They loved them and the movement allows them to focus while they are moving.

Really takes pressure off back and keeps me loose, highly recommended!
