We see chairs made up of various materials, such as wood, iron, plastic, bamboo, cement and stones. Following are some desirable properties of materials which can be used to make chairs. Which materials used to make chairs fulfil these properties the most? (i) Hardness (does not bend or shake on sitting even after long use). (ii) Lightweight (easy to lift or to take from one place to another). (iii) Does not feel very cold when sitting during winters. (iv) Can be cleaned regularly and made to look new even after long use.

(i) Hardness
Best Materials: Wood and iron.
Both materials are sturdy and maintain their shape under weight, providing durability and stability over time.
(ii) Lightweight
Best Materials: Plastic and bamboo.
Plastic is generally very lightweight, and bamboo is also lighter than wood or metal, making them easy to move.
(iii) Does not feel very cold in winters
Best Materials: Wood and upholstered chairs (which can include materials like foam).
Wood has a warmer feel compared to metal, while upholstery adds insulation and comfort.
(iv) Can be cleaned regularly
Best Materials: Plastic and metal (like iron).
Plastic is easy to wipe down, while metal can be cleaned and polished to maintain its appearance without much effort.
In summary, for different properties, materials like wood and iron excel in hardness, plastic and bamboo are lightweight, wood or upholstered chairs provide warmth, and plastic and metal are easy to clean.
