How it actually works

The chair starts as this in its open state. The red is the bean bag. The left part is just fabirc with no spines in it where as the one on the right has 3 spines in it made of polypropylene.

The right side is then  pulled up and as this happens the the fabric unravels and starts to stretch out with the help of the spines.

The right side is now hanging off the fabric which is attached to the base and will just hold in the position using just its weight. The spines mantain shape .

The left side can be attached to the right hanging side using buttons ( to be expanded and drawn on) to do the cocoon up . The fabric on the left side will hold the hood in place if knocked. The left side is also attached to the base. The user  can do the buttons up on the inside.
