Comfortable option for going to any gatherings away from home. End up at home afterwards in better shape than usual. The norm is stuck in hard folding chairs. Plastic buy 2 get 2 free.

This eliminates the heads or tails games you end up playing in your head about going to that event or not. 
Do your body a favor and BUY ONE!!!!
