Piano chair made in Japan by leading piano accessories manufacturers, Konan and Yoshizawa. The back chair is also known as the Tomson chair, but the model number is the NO5 type. Although the manufacturer has various model numbers, we stock and sell either Konan "NO5-NEW-BLK" or Yoshizawa "5K-BLK". Usually, the seat leather color is engine, but this product is covered with black leather. There are few factories that can be manufactured in Japan and this year are very low distribution, and waiting for several months from order to arrive. This is one of the items that we have already ordered in advance to maintain some inventory.
