Stationary auditorium chair with back table with floor anchoring Student

Steel frame: inclined-vertical rack from 60x30mm profile, horizontal rack-support of seat rotation axis from 60x30mm profile, horizontally inclined rack-support of table top from 30x30mm profile.
Each steel frame has two places of attachment to the floor: one to the horizontal plane of the floor, the second to the vertical plane of the step - this completely eliminates swaying.
The seat axle is 14mm diameter with anti-friction fluoroplastic bushings for easy, quiet rotation. All ends of the chipboard parts are finished with 2 mm thick PVC edging. All ends of the steel profiles are covered with elastic plastic plugs.
For table tops, 22 mm or 26 mm thick chipboard is used.
