Prototype 3

Prototype 3: U shape with handle

Testing the U shape and the extra handles that could be added

Expected positive: nothing

Unexpected positive: nothing

Expected negative: She don't use the handles. With the handle, you lose space so the ouside shape should be bigger. The shape (U) for the hole is not comfortable.

Unexpected negative: Not that stable anymore: if you lean on the handle, the chair tilts. Handles are in the way of the seating. It's better to use your whole hand during the transfer. 

Score: In comparison with other prototypes is this not good (3/10)

Maybe turning the U-shape is better? The handle isn't used, so we could leave that away.
