Answer:
Underbracing refers to the arrangement of stretchers on chairs, tables, and stands with legs in such a way that they form a structure that holds the legs together and provides stability. It involves adding horizontal supports, called stretchers, between the legs, usually near the bottom of the furniture item.
The purpose of underbracing is to prevent the legs from splaying outwards or collapsing, ensuring that the furniture remains sturdy and can bear weight without wobbling or tipping over. It also helps in distributing the weight evenly across the legs, increasing the overall strength and durability of the item.
Underbracing can be seen in various furniture pieces like chairs, tables, and stands, where two or more stretchers are attached between the legs. These stretchers are commonly made of wood or metal and are positioned parallel to the ground, reinforcing the legs and providing additional support.
By incorporating underbracing into the design, furniture manufacturers can create robust and reliable products that can withstand regular use and heavy loads. This technique has been used for centuries and is still widely used today to ensure the stability and longevity of furniture with legs.
