I made a hammock chair after getting the idea while reading SteelerNation's combination chair thread.
It is made out of JoAnn Fabric's 1.9 ripstop nylon and is 54"x40".
I wanted to be able to hang it between two trees or just one so the lower end has both a channel to gather it and pole pockets. The upper end attaches to the tree with a tree hugger/marlin spike/whoopie sling just as a regular hammock.
I don't like the looks of the stress at the pockets and will probably remake it with a 200D nylon pocket and reinforcing patch on the top side.
It works well as a two tree chair and is VERY comfortable as a no squeeze one tree chair with poles.
