Huge disappointment for the price. Finally got to use these on the first nice evening of spring and it's already degrading. After only an hour and a half on the FIRST real use, the straps of the seat started sagging noticeably. You can see in the photos where my friend was sitting and how much lower it was compared to the other seat. I've only had these for a little over a month. There is no reason for this much wear. I want my money back.
