This review is after a month of use. The frames are sturdy, nice overall chairs. But the mesh material is not very sturdy/strong. After only a few uses, the material sags. As it does, the person then ends up sitting on the cross bars underneath which are solid and hard and uncomfortable pressure points. I weigh only 180 pounds, I can&#x27;t imagine a heavier person using these without a full chair pad to keep the cross bar pressure points away from the body.
