SD-331 SEAT

The SD-331 fixed seat is designed for classrooms in schools and universities. It features a swing mechanism that allows the seat to move smoothly between horizontal and vertical positions. As a result, students can enter or exit their seats easily with a natural sliding motion. In addition, students can sit without removing personal belongings, avoiding the feeling of being confined between the seat and the desk. This design improves comfort and ease of use during class transitions.

The SD-331 achieves an ideal balance between comfort, space efficiency, and circulation. Its ergonomic seat and backrest promote proper posture and sustained comfort throughout extended use. The model also offers a wide range of finish options. The seat and backrest are available in beech plywood or injection-molded polypropylene. Upholstered polyurethane foam cushions can be added to one or both elements. Fixed writing desktops are constructed from high-density fiberboard with melamine surfaces and rounded PVC edges.

USES AND APPLICATIONS

The SD-331 system adapts easily to compact classrooms where row spacing is limited. It preserves comfort while providing a generous writing surface.

It can be installed on flat, sloped, or tiered floors. Additionally, it supports straight or curved row layouts, with configurations tailored to each project.

SUSTAINABLE DESIGN

The SD-331 supports upholstery woven from recycled PET polyester yarns. Every component can be recycled independently, helping reduce environmental impact and support a closed materials lifecycle.
