Hokki Stool, Flexible Ergonomic Seating Stool for Kids and Adults, 15" Seat Height, Light Blue

I purchased these for my kids in the hope that it would help my eldest focus. It helps a little, which I'll take, but it's not a miracle cure. The kids love them though as do their friends. I even have one a work and it's a big hit, so I think it's worth the investment. If definitely makes my low back feel more comfortable on days where I'm not moving much.

My students always love this stool. The only drawback to this stool is that the soft bottom easily grips grit, pencil lead, etc., which then leaves marks as the stool rocks around on the floor, dragging and grinding the dirt and grit into the surface.

Very well built. Really helps maintaining a straight upright posture. Cannot slouch as in a regular chair. Easy to be carried around by a 6-8 years kid.

Actually grandson's teacher and mom are loving it. He appears to be concentrating better in class.
