We think that the value of an object is expressed both through design and through the philosophy behind it, and that the choice of seating plays a key role in the design of spaces: concentrating, meeting or relaxing are activities that require different design and philosophy.

It is a synesthetic experience involving all the senses.

Vision in choosing colors that relax, energize or promote concentration.

Hearing through shapes and materials that generate reduced noise impact.

Touch: the seat is in direct contact with our body, and the choice of upholstery conveys feelings that affect the state of mind.

The seats are made by highly skilled workers who ensure total quality and attention to detail.

The increase in production volumes has not undermined the importance of tailoring in the production of manufactured goods, a quality that distinguishes true Made in Italy.

Ethical and sustainable design

Design research, attention to detail and respect for the environment have always been the basis of all SITLOSOPHY® seating projects. Each new model is the result of collaboration between the in-house research team and professional designers, who are able to combine and synthesize originality, aesthetic pleasantness and ergonomics.

The design of the seat makes it recognizable and is a source of inspiration for designers in finding new space arrangement solutions. The form is all the more effective the more it helps those who use the space to exploit its full potential. In a context of sudden and constant change, flexibility and modularity are an added value because they allow the space to be redesigned according to the activities to be carried out. The ethos of sustainability is embodied in the choice of materials used, which are of high quality and have a low environmental impact. In recent years, supplier selection has favored wood from responsibly managed forests, textiles and plastic elements derived from recycled or easily recyclable materials.
