The design and selection of outdoor stadium seats need to take into account many factors. The following is an introduction from the aspects of materials, size, design layout, special needs, etc.:

Material selection

Polypropylene (PP): light, impact-resistant, waterproof and moisture-proof, and has good processing performance. It can be injection molded as needed to produce seats of various shapes and colors. It is widely used in stadiums, school playgrounds and other places where temporary or long-term use of seats is required.

Polycarbonate (PC): a high-performance plastic material with excellent transparency, impact strength and heat resistance. It is more durable than polypropylene, can withstand greater weight and impact, and has good weather resistance. It can maintain stable performance for a long time in harsh environments. It is suitable for stadiums with high requirements for seat quality and long-term use, such as professional football fields and basketball courts.

High-density polyethylene (HDPE): hollow blow molding manufacturing process, one-time processing and molding, with smooth edges and corners on the seat surface, concentrated molecular weight, high bonding strength at the joint seam, aging resistance, impact resistance and other characteristics. It is often used in the manufacture of sports stand seats, especially those that need to withstand the weight of a large number of spectators and frequent use.

Other materials: PVC, PU and other materials also have wear resistance, fire resistance and other properties, but may differ in different aspects (such as cost, processing performance, durability, etc.).

Size standard

Seat width: generally between 450mm and 600mm. There are also claims that the seat width of a seat with a backrest should not be less than 450mm. Considering factors such as ergonomics and the average shoulder width of the audience, the specific width will be adjusted according to design requirements.

Seat height: usually 400mm to 450mm. There are also claims that the seat height is between 430~480mm to ensure that the audience's feet can be naturally placed flat on the ground and maintain a comfortable sitting posture.

Row spacing: The row spacing of domestic stands is mostly 0.8m, but there are also venues that adjust the row spacing according to specific needs, such as 850mm for ordinary audience seats and 1700mm for VIP seats. It is necessary to ensure that the audience has enough space to move around and avoid congestion.

Seat spacing: The spacing between seats should be kept at around 450mm to ensure that the audience can enter and exit the seats freely while avoiding mutual interference.

Design layout

Audience comfort: The layout of the seats should ensure that the audience can stay comfortable while watching the game, including the design of factors such as the spacing, total width, relative height and inclination of the seats. Scientific and reasonable seat spacing can prevent congestion between spectators and ensure that the audience has enough space to move; and comfortable seat width and height can reduce the audience's fatigue and enhance the viewing experience.

View considerations: The arrangement of seats should ensure that the audience can clearly see the game field and avoid being blocked by the audience in front. A stepped infield design can be adopted so that the audience in the back row can see over the audience in the front seat. At the same time, the inclination of the seat is also adjusted as much as possible to reduce the visual blind spot.

Safety: During the layout process, it should be ensured that the emergency exits, fire evacuation passages and emergency facilities are set up in accordance with the specified inspection standards and regulations. The seat installation should also be firm and reliable to avoid accidents in emergency situations.

Special needs

VIP seats: The seat width may reach 550mm or even wider, and the row spacing may also be larger to provide a more spacious and comfortable seating experience.

Disabled auditorium: The seat width and row spacing may need to be larger so that disabled people can sit and stand up conveniently. At the same time, the disabled auditorium must also be equipped with corresponding barrier-free facilities, such as handrails and wheelchair parking areas.
