PET Felt technology: from bottle to chair

In our design and production processes, we are always looking at where environmental thinking and economic improvement intersect, resulting in minimal waste. The way we utilise PET emphasizes this vision. 

The seat of the LJ 2 is made from recycled plastic bottles. PET Felt technology transforms the labour-intensive production into a single smart 3D pressing technique. PET Felt is recycled and recyclable, offering great comfort and sustainability.
