Stadium Seating Chairs : BLM-9000 series (All weather type)

This two-piece stadium seat (bench-type seating) features separate backrests and seats, and is especially effective for stadium and arena renovation projects. The rounded forms of the backrest and seat are designed to fit the human body, providing excellent support. As a global standard in stadium seating, it is suitable for both indoor and outdoor sports facilities, including stadiums, arenas, domes, and gymnasiums in Japan and worldwide.

Shortened renovation timelines through reuse of existing legs

This solution allows existing chair legs to be retained while replacing only the seat components. It is particularly effective when upgrading from one-piece spectator seating to a two-piece configuration. Reusing existing legs reduces both construction time and cost.
By converting to a two-piece design, the seat automatically tips up when unoccupied, increasing aisle space. In addition, because the seat depth no longer impacts aisle clearance, the seating surface can be made larger. This improves comfort both while seated and when passing through rows, contributing to an upgraded facility experience. Reusing existing components also reduces waste, making this an environmentally responsible choice.
＊If existing legs cannot be reused, new legs will be quoted separately.

Barrier-free safety design to prevent accidents and injuries

The design prioritizes safety through barrier-free principles, helping to prevent incidents such as finger entrapment. The seat-lift mechanism is fully integrated within the seat, with no exposed moving parts. In addition, gaps between structural components beneath the seat are covered to eliminate potential hazards.
When installed on tiered flooring, a gap is created between the seat and the tier behind; this gap is minimized to reduce the risk of missteps or falls.

Extensive options

The series includes both low-back and high-back models, along with a wide range of options. Backrests and seats can be fitted with cushions, and accessories such as cup holders and seat-number plates can also be added.

Material (HDPE) & Manufacturing Process (Blow Molding)

Characteristics of the BLM Series

The BLM (Blow Molding) Series utilizes high-density polyethylene shaped through advanced blow molding techniques. The resulting double-shell hollow structure delivers both structural strength and ergonomic comfort. Manufactured using a process renowned for its exceptional impact resistance among plastic molding methods, these seats are highly resistant to cracking even when struck by flying baseballs. Notably, they offer superior low-temperature impact resilience compared to the polypropylene (PP) injection-molded seats widely used in Europe.

In addition to excellent heat and water resistance, HDPE offers high resistance to chemicals and oils, making it an ideal material for stadium seating prone to food and beverage spills. To prevent fading and degradation caused by outdoor exposure, UV absorbers are integrated directly into the resin.

Key Features of the BLM Series

Developed based on ergonomic principles to follow the natural curves of the body. The double-shell hollow structure absorbs impact when sitting while providing a cushioned, highly comfortable viewing experience.
