I purchased a Portable Chair at a rummage sale last year and liked it so much I wanted a second. It's well padded and sturdy. I didn't hesitate to buy my second from Wayfair when it came on sale. My son is on a high school wrestling team which means that his dad and I spend long hours sitting on hard bleachers. This chair got me through last season and now we will both be comfortable come next season. I'm not sure that I would use this chair on sand or dirt but I think it would be ok on grass.My only criticism is that it doesn't fold in half making carrying cumbersome. There are backpack style straps for carrying but they're not very useful or comfortable. Perhaps a carrying case or a luggage style shoulder strap would have been a better design.All in all, I highly recommend this chair.
