Eleven unique PET felt blends, each with its own texture and depth. Minor colour variations between batches are a natural result of the production process.











Two standard frame colours are available: black (RAL 9011) and white (RAL 9010). Beyond these, specify any RAL colour for the frame, add upholstery, or combine options to match your interior.

The powder-coated steel frame can be finished in any RAL colour. Match it to the PET felt seat or create contrast for a bolder look.

For extra comfort, add seat upholstery in fabrics from the Kvadrat collection. A practical upgrade for settings where people sit for longer periods.





LJ 3's seat is made from PET felt, a durable material produced from recycled plastic bottles. Soft yet strong, with natural sound-dampening properties. De Vorm's single-mould pressing technique shapes the PET felt into a ready-to-assemble form, replacing multiple traditional production steps with one. The result is an ergonomically curved shell with varying thickness and a distinctive felt texture.
