The chairs are attractive, wide, comfortable and sturdy. However, the brackets that hold them together (side by side) are flimsy and do little to help (we zip-tied ours together for extra stability and to deter people from moving them.) Also, the screws that hold on the backs go straight into plywood, it would be better if they were bolts into threaded insert. These chairs should last a long time if left in one classroom or setting. I would not want to test the longevity by moving and stacking them every week.
