SD-331 SEAT
The SD331 fixed seat for classrooms in schools and universities is equipped with a “swing mechanism”. This feature allows the seat to be positioned in the horizontal or vertical plane easily and effortlessly. It operates in a natural sliding movement when resting the legs on it, allowing the student to occupy or vacate his seat without any effort.
Or, the occupant is able to sit without having to previously leave ones belongings thereby avoiding the discomfort or the feeling of being “trapped” between the seat and the table.
The SD 331 model stands out for its perfect balance between comfort, space utilization and circulation.
The seat and backrest have been designed with ergonomic shapes to ensure a correct seating position and comfort during the time of use.
It stands out for its wide range of finishes. The seat and backrest can be manufactured in beech plywood or in polypropylene injection, and can incorporate an upholstered polyurethane foam cushion in one or both elements.
Likewise, the fixed writing desktops, which 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-331 SEAT
The SD331 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-331 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.
