Prototyping

Weaving between the frame

 

The weaving is simple. The cricket ball offcuts will be woven in long chains and linked around the outer and inner circular frames. It will simply be tied at each end and tightened so there is no sag around the sides. The seat will be a separate woven piece and to create sag fro the seat, it will be woven into a net. This method is the easiest, and requires no threads, screws or adheasives.

Anthropemetric Considerations

The average human height is 168cm.

GUIDELINES FOR DESIGN

MULTI-PURPOSE SEATS

Multi-purpose seats are intended for a variety of uses: in dining rooms, bedrooms, work areas, and as spare chairs. They are also used in public spaces such as waiting rooms, conference centres and libraries, where they often have to be stacked for storage. General requirements for seats can be applied to multipurpose chairs. However, such chairs will not usually be maximally comfortable in all situations and compromises will often have to be made. It is difficult to design a seat that is comfortable both for a forward-inclined posture (a dining table) and a backward leaning posture (listening to a talk). Taller and shorter users may be particularly uncomfortable with certain chairs.

Recommendations:

• The seat and backrest should be upholstered with a gently-rounded lumbar support.
• The seat surface should be gently moulded with slight concavity under the buttocks.
• The depth of the seat should not exceed 430mm in order that the backrest is effective for smaller users.
• The height of a flat seat surface should be 400–460mm.
• The material for the seat cover should allow for air circulation and not be slippery.
