You are to design a chair that is suitable for production as a rotational moulding and should not exceed an enclosed volume of 1m3. Other than this the brief is entirely open although you should consider the following:
Ergonomics – Does your design fit the target market? (As defined by you)
Aesthetics – Does the design have an appropriate visual language?
Tactility – Does the chair feel right? Especially in skin contact areas.
Stability – Given the production process, will the design feel secure in use?
Strength – Will the design support a 95th %ile user from the target market?
Remember that the target production method is rotational moulding, you will be given the opportunity to visit a production facility to familiarise yourself with this process.
