Prototype 1

Prototype 1: square shape with hollowed handles

First of all is the basic prototype stable enough? Then the size of the outside shape and the size of the whole is important. Also the handles.

Expected positive: chair is stable enough and outside shape is big enough
Unexpected positive: She don't really need the handles but they can be added to have more grip
Expected negative: already quite stable but this can still become better
Unexpected negative: the hole is not big enough, she feels her sitting bumps on the edge

Score: in comparison with later prototypes this prototype scores good (6/10)

This prototype is  quite good, so later we adapt this (for example the size of the hole)
