SD 777 SEAT
The SD 777 system for lecture halls and classrooms in schools and universities. It is equipped with an oscillating mechanism. This feature allows a movement of the mast that supports the seat and backrest assembly. It moves from the folded position next to the table; to the working position when the student takes a seat.
When the SD 777 is folded, it allows wide spacing between rows, since the closed envelope measures. Similarly, when the student is seated, the seat can be moved to a more forward position by tilting the body forward to increase the rear circulation area.
The oscillating mechanism, integrated in the standard of each seat, incorporates a spring and a damper. The spring defines the movement of the mast and the damper slows down its speed, avoiding shocks when the seat is folded against the table, as well as any kind of noise.
Since it is not fixed to the rear table structure, the vibrations and movements that one element transfers to the other and that may cause some discomfort to the student are completely eliminated.The SD 777 model stands out for achieving a perfect balance between comfort, space utilization and circulation.
The SD777 has been designed to move and the use of robust component parts makes it a suitable product for intensive use facilities. Likewise, the ergonomic shapes provide a high degree of comfort and guarantee a correct seating position for the student.
It also stands out for its wide range of finishes. The seat and backrest can be manufactured in beech plywood or in polypropylene injection, and may incorporate an upholstered polyurethane foam cushion in one or both elements.
Similarly, the fixed writing desktops are made of high density fibreboard covered on both sides with melamine and with rounded edges finished in PVC.

USES AND APPLICATIONS OF THE SD-777 SEAT
The SD777 table and seat series can be adapted to small spaces, even in classrooms where the space between rows is limited, without sacrificing comfort and having a large writing desk.
It can be installed in classrooms with flat, sloping or tiered floors, and in layouts with straight or curved rows, adapting the manufacture of the product to each project.

SD-777 SUSTAINABLE SEAT
This product allows the use of upholstery woven with polyester yarns made from recycled PET bottles. In addition, to ensure the closing of the materials cycle, each and every element used in its manufacture can be recycled separately, thus reducing the ecological footprint.
