This product is beyond belief. Versatile and easy to use. My students could not get enough of it. All of my students loved using it in the classroom and wanted to know the price. My fellow teachers were amazed at its adjustable features for height.

The RKR Adjustable Stool is a perfect solution for active students in a classroom allowing students to move naturally while staying in a stationary position. A constant state of movement occupies the student so their focus can remain on learning. Weighted on the bottom with a special floor grip, the RKR is similar to the exercise-ball concept, but with a smaller footprint and looks great in any space. Teachers love them too! The self-balancing feature allows an instructor to make quick and easy transitions from one teaching mode to the next. Use them in an art room, classroom, or lobby space, but don’t stop there. The RKR is suitable to all kinds of applications and is available in array of seat fabric and vinyl options.

Comments from other GEI teacher reviewers

“The RKR Adjustable Stool provides great optional seating. It provides movement for those students that need to wiggle during class. The height adjustment helps to meet the need for those students in middle and high school. Students always see cool seating in the elementary; now they have cool seating for high school classrooms.”

“I feel like this stool definitely has its place in the secondary classroom. It is a step up from the traditional ‘ball chair.’ Ball chairs have a large footprint in the classroom and this stool is more compact and is more likely to fit under desks and tables, freeing up classroom space.”
