Document: We go to a lot of basketball games and benches are uncomfortable. This chair makes sitting through two games enjoyable.
I ordered two of these, one for me and one for my girlfriend. We go to the local race track every Sunday, and we were growing tired of sitting on the hard wood benches. I finally caved and ordered these. They are great. Very comfortable. The only downside is they are pretty heavy. Not terrible, but could hurt your arm if you are carrying a couple of these at a time. Anyone that sits in it asks me where they can order one.
These chairs are the only way to go when sitting in bleachers, indoors or out. There is no center bar in the back piece making contact with your back. The elastic cord cinching the bottom together really makes the chairs comfortable, (not to firm or to soft). We recently purchased two chairs in addition to two chairs we purchased three years ago. Product is very sturdy and should last many many years if not abused. We keep ours in the back of our vehicle nine months out of the year.
we go to many games for our daughters' teams and these charis, we have 2, are great in support and cushioning.
Thanks to these seats, I can go to both games. Shipping is fast. Product is good. Kids and I are happy. Life's good now.
Baseball season will no longer mean back pain and my butt falling asleep. Now we can view in style! Go Humboldt Crabs!
Very sturdy, lightweight and easy to carry around. The most important thing is it is VERY comfortable. Perfect for my dad to go to his grandchildren's ball games!! !
I have one myself and have bought one for my daughter and son-in-law! We go to many sport games, so this is needed in the bleachers. Saves on the back! !
This chair has been a life saver, I used it when I go to the many dance competitions for my daughters and have to sit in bleachers most of the day. I can tolerate sitting there now.
It is the best way to sit in the stadium for hours watching games. No more backaches from the bleachers. Great deal.If you like sitting in comfort watching games at the stadium this is the way to go.
Answer: no
