One Seat. Your Own Little Retreat.

With its backless design, F3 invites people to sit from either side, creating a welcoming spot to pause at any moment. Integrated storage keeps magazines and everyday essentials within easy reach. A lounge space that feels as good as it works.

Flexible by Design. Collaboration in Motion.

Screens, high tables, and modular seating come together to create a flexible workspace for spontaneous collaboration. Semi-open layouts bring people closer, encourage fresh thinking, and turn a simple gathering into a new idea. Where conversations begin, ideas take shape.
