Grandstand seats
The seat features an internal iron frame with dampers and springs, ensuring smooth return to its original position, durability, and noiselessness. The shock-absorbing and sound-dampening pads and limit accessories include a machined limit post with a soft rubber ring integrally molded onto the seat cushion. This provides cushioning when the user sits down, enhancing comfort, and eliminates noise during seat retraction, achieving a quiet operation.
The steel frame surfaces undergo pickling, rust removal, alkali cleaning, degreasing, phosphating, and drying processes, followed by electrostatic powder coating (matte black or gray). The iron frame wall thickness is no less than 1.8mm. All welded joints are straight, firm, and free of defects, with welds ground smooth. All components are straight, horizontal and vertical strips overlap vertically, and interlocking joints fit perfectly. The feet are secured to the ground with expansion bolts. The assembly is flat, reliable, and stable.

Parameter Specification
JZX-YQ101
Parameter Specification
Polyurethane foam, ABS engineering plastic, imported linen fabric, and steel frame.
Parameter Specification
Seat armrest center distance: 580mm, back height: 1000mm, seat height: 450mm, seat depth: 440mm
1. Backrest material: Seven-layer hardwood molded board, manufactured through high-frequency and high-pressure processes, providing strong support, impact resistance, and deformation resistance. The overall sound absorption rate is 0.5, eliminating echoes within 0.1 seconds, ensuring excellent seat breathability and a noise-free venue, significantly improving the theater's acoustics.
2. Seat and back foam: High-density cold-foamed molded sponge, ergonomically designed based on human sitting posture principles, offering high elasticity, comfort, durability, non-deformation, resistance to aging, strong absorption capacity, and a comfortable seating experience. Other specifications are as follows: Backpack density: 45-50kg/m³. Seat pack density: 50-55kg/m³, seat outer panel thickness reaches 15mm.
3. Fabric: High-grade imported special linen flannel fabric, stain-resistant and fade-resistant. (Multiple colors available). 4. Concealed folding writing pad, which can be stored inside the armrest legs, making efficient use of space. The round iron writing pad stand abandons the easily broken aluminum alloy stands commonly used in the market. This round iron writing pad stand has a load-bearing capacity of 55KG and is durable.
5. The armrest surface and front cover are made of imported beech wood.
6. The armrest legs are made of steel plates no less than 1.8mm thick, formed by hydraulic pressure and welding. The base plate of the armrest legs is stretched and formed from steel plates, fixing the seat to the floor.
