I purchased the gray 17 1/2 Flex-Space Ergo chairs. Best purchase ever! The quality and color is excellent. Very comfortable and my students love them.

My school ordered these for our classrooms. We were disappointed to realize that the casters on these chairs are not locking casters. Some of my students have a hard time sitting on them as they roll out from under them as they are trying to sit down. I have actually put them up and gone back to our old chairs because of all of the difficulties. They are comfortable and I love the colors but not very practical for young children
