Another type of indoor bleachers are low 2- and 3-row mobile indoor sports bleachers. Bleacher’s construction is designed from steel profiles covered with furniture boards, which are available in a wide range of colours and patterns. In addition, the bleacher is equipped with a wheeling system that enables to move it freely from one place to another. Wooden bench-like seats are made of solid or finger-joint wood (plywood is also an option) and are finished in clear lacquer. In standard the floor is made of anti-slip plywood. Due to applying furniture boards the construction of the bleacher can function as rebound boards or wall-protection. It is also possible to design and carve vent holes in the furniture boards. This solution is useful if in the sports hall there are some radiators that need to be covered.
