Introduction

LJ 3 PET Felt Bar Stool brings the slim lines and functional character of the LJ series to bar height. The ergonomically curved seat is moulded from PET felt made of recycled plastic bottles, using a smart 3D pressing technique that replaced multiple traditional production steps with one. The high-strength recycled steel frame provides a stable, open base. Available in eleven PET felt colours with full frame customisation, LJ 3 suits bars, restaurants, and informal working spaces.

Material

Made from recycled PET felt

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.
