bleacher

A bleacher is a type of tiered seating, typically made of long benches, used to accommodate spectators at sporting events, schools, and other public gatherings. Bleachers are often found in outdoor stadiums, gymnasiums, and parks, providing a simple and cost-effective seating solution. They can range in size from a few rows for a small local game to expansive structures capable of seating thousands at major sporting arenas.

The design of bleachers can vary significantly. Some are basic, flat benches arranged in rows, while others incorporate raised tiers to improve sightlines. Materials commonly used include wood, metal, or plastic. Wooden bleachers were historically common but are often replaced by more durable metal or plastic options due to maintenance and safety concerns. Metal bleachers are frequently constructed from aluminum or steel, offering strength and resistance to the elements. Plastic bleachers, often made from recycled materials, provide a lightweight and low-maintenance alternative.

Safety features are crucial in bleacher design. Railings are often installed on higher tiers to prevent falls, and steps or ramps are incorporated for access. Local building codes and regulations typically dictate the design and construction standards for bleachers to ensure spectator safety. Portable bleachers are also available, allowing for temporary seating arrangements at various events. These can be easily moved and set up as needed. The term "bleacher" itself is thought to originate from the color of unpainted wood, which would "bleach" in the sun.
