What is the material of the auditorium chair suitable for school use?

We all know that  auditorium chairs  are usually used in public spaces such as conference rooms and auditoriums. Good materials greatly affect the service life of auditorium chairs. So do you know what the material of the auditorium chairs suitable for school use should be?

 1. The seats and back panels of auditorium chairs suitable for schools are made of seven-layer beech wood molding boards, which are made of high frequency and high pressure. They have strong support, impact resistance, deformation resistance, and unique honeycomb sound-absorbing air holes; the overall sound absorption rate is 0.5, and the entire venue can eliminate echo within 0.1 seconds, ensuring good air permeability of the seats and no noise in the entire venue.

2. The seat and back foam are made of polyurethane foam. According to the engineering principle of human sitting posture, it is made of anti-deformation, high elasticity, comfortable and durable after cold-setting and foaming. The foam density of the seat is >50kg/m³, and the density of the back foam is >45kg/m³.

3. The fabric is made of imported hemp flannelette, and its flame retardant performance has passed the national qualification test standard (multiple colors are available).

4. The armrest surface is made of beech solid wood, and the armrest feet are made of high-quality aluminum alloy through die-casting, with a hidden writing board inside;

5. The central axis adopts a steel rod with a diameter of Φ14 to support and reset the seat; the seat adopts a built-in automatic recovery device, so that the seat can automatically reset, with fast recovery speed, no noise, and zero failure.
