This is as far as I got with mine before I ended up just getting my AC system recharged.
I used vinyl string to tie 4 parallel loops of 1/8"ID 1/4"OD tubing to a sheet of plastic mesh. I was then going to connect them to manifolds to adapt to 1/2" ID tubing.
It's very comfortable to sit on and lean against and if I were to kink any of the tubing, the four parallel loops prevents the flow rate from being affected. Having parallel loops also reduces baseline restriction.
