The Ethnicraft Oak Bok Dining Chair in black. All of Ethnicraft designs use timbers which support TFT, a not-for-profit organization that promotes responsible forest management. This dining table has been built from solid European Oak sourced from well-managed French and Serbian forests. Oak timber was chosen by Ethnicraft due to its natural occurring splits and knots which each piece unique. The timber for this piece has been tinted with a water-based colour and then oiled giving it a high quality finish.
