The Wooden Chair is used as a decoration along with a table for any NPCs to move into a house. It acts as a background item. 4 Wood are needed to craft a Chair. A Chair needs to be present in the player's vicinity in order to craft Goggles, a Watch or a Depth Meter. The specific reasoning behind this is unknown, but it is assumed to be because the player would need to sit down to make them.
■When placed the Wooden Chair will face the direction the player is facing.
■Wooden Chairs can be collected by hitting them with a hammer.
