Arm stay

**Arm stay**

An arm stay is a structural component typically used in furniture, construction, or mechanical assemblies to provide additional support and stability to arms or extended parts. In seating furniture such as chairs or sofas, an arm stay helps reinforce the armrest, preventing wobbling or sagging over time. It can be made from various materials including metal, wood, or plastic, depending on the design and strength requirements. Proper use of arm stays enhances durability and comfort, ensuring that arm-supported areas maintain their shape and function through extended use.
