I bought a walmart hammock for $25, cut it in half, had a channel sewed in both of the cut ends, then added whoopie slings, tree straps and carabiners to make 2 hammock chairs.
A friend and I went for a bushwhack snowshoe in a local county forest today. When we stopped for lunch we gave the chairs a try. Very comfortable.
When we got back to the cabin she had to leave to get to a late afternoon meeting. I decided to take a nap by hanging the chair from the rafters.
