Before understanding the technical parameters of the amphitheater chairs, we must first understand what is the composition of the amphitheater chairs? Amphitheater chairs are a kind of public seats, and most of them are composed of four parts: seat, back, armrest and feet, and the structure is generally steel-wood structure or steel-plastic structure.

After understanding what is the amphitheater chair arrangement, let's understand some more important technical parameters (values are suitable for most spaces, and the actual situation can be adjusted appropriately). First, some basic parameters of the seat:

1. The height between the back of the chair and the ground: 1030mm

2. Seat height from the ground: 430-450mm

3. Armrest height: 580-660mm

4. Seat distance: center distance: 580-600mm

5. Row spacing: 900-950mm

In addition, there are some material parameters of the seat:

1. Seat sponge: high-density rebound sponge, with high resilience and super soft characteristics, the density of backrest sponge is mostly ≥40-50kg/m³, and the density of seat cushion sponge is mostly ≥50-60kg/m³.

2. Seat fabric: high-grade velvet fabric, which has the characteristics of wear resistance, color change resistance, moderate softness and easy cleaning.

3. Seat and back shell: with sound-absorbing design, to ensure consistent absorption volume at different levels, different angles, and different occupancy rates.

4. The armrest frame and the tripod are welded together, and the surface is generally treated with electrostatic spraying, which is rust-proof and durable.

5. Cushion recovery mechanism: There are generally two types of cushion rebound design and spring torsion design.

After reading the parameters of the above-mentioned lecture theater chairs, I believe you have a deeper understanding of this, and I hope it can help you choose the lecture theater chairs.
