Question

An image of a chair is shown below. Identify the material most suited for its manufacture. 

• A. Steel
• B. Plastic
• C. Laminated wood
• D. Cast iron

Hint:

Injection-molded plastic allows designers to create lightweight, seamless, and ergonomic furniture shapes that other materials cannot easily achieve.

Answer 1

The Correct Option is B

Step 1: Observing the chair design.
The chair shown has a seamless, single-piece form with smooth curves and no visible joints. This type of flowing geometry is characteristic of molded materials rather than metals or wood.

Step 2: Analysis of material suitability.
- (A) Steel: Steel cannot easily achieve this seamless curved form without welding or bending marks, and would be unnecessarily heavy.
- (B) Plastic: Plastic—especially injection-molded polypropylene—is ideal for such smooth, continuous, lightweight designs. It allows complex shapes in a single piece.
- (C) Laminated wood: Laminated wood can bend, but cannot form such tight curves or thin profiles without losing strength.
- (D) Cast iron: Cast iron is very heavy and unsuitable for modern lightweight furniture.

Step 3: Conclusion.
Thus, the most appropriate material for manufacturing this type of seamless, curved chair is plastic.
