Ok so i have alot of chairs. Helinox arb cheap quads blur ridge etc. For the past year I have been using this crazy tripod from Bass Pro. $18 and best chair ever. Everything that is wrong with a quad style chair this is right. Quads promote bad posture almost all recline to much for eating at a table, they are heavy, bulky and cut circulation in the legs.
The tripod allows you to sit up straight and when u lean back your back actually is supported properly. they are light, compact, you can eat at a table and even sitting in them for hours is ok because the front leg is spring loaded and cushy! Oh and did I say $18? Let me say it again $18!
