We had purchased 3 of these chairs for a small physically challenged workout group; some parts of the workout are performed seated rather than standing. These chairs are as stable as iron! Once you put them in place, they don't budge or tip with movement. No moaning or creaking sounds. They are rock solid and fabulously comfortable. The price was extremely reasonable. If anyone has need a for a work-horse of a folding chair at a very reasonable price, this is it! Thank you so very, very much :)
