Auditorium armchair Alis
ISI by Ernest Chair

Seat especially designed for theatres, auditorium and conference halls.
Seat and backrest made of beech plywood, 12mm thick, and finished with 2 layers of polyurethane varnish. Upholstery made of open-cell polyurethane foam (self-extinguishable according to legal prescriptions), covered with M-1 fireproof fabrics with an additional underlying M-1 layer –shade to be chosen by the customer.
Sidearms made of high density waterproof MDF panels finished either with beech plywood and 2 layers of polyurethane varnish, or upholstered with fireproof M-1 barrier and fabrics, just like seat and backrest.
Backrest is fixed to the set by means of two side components made of extruded aluminium. Thus, the row achieves uniformity and firmness. Sidearms also enclose the folding socket joints, which allow the seat pan to fold by means of a spinning axle and a torsion spring, determining the automatic reversion.
They enclose the folding socket joints, which are made of injected polyamide, very resistant to mechanical demands, and do not require maintenance.
Fixing to the floor is achieved by means of a steel plate support, 10mm thick, onto which the sidearm is anchored. Every support has two orifices for its fixation to the pavement. Powder coat finishing –shade to be chosen by the customer.
