Abstract
The present invention discloses a compound lumber product, relating to the technical field of wooden materials for making furniture, and particularly to a compound lumber product that may be used for making furniture. The compound lumber product includes a core lumber and side-members surrounding the core lumber. The core lumber may be one piece or formed from several core members. The side-members may be single-piece or formed by joining together several high-grade wood boards or strips. Side-members are arranged side by side around the outer surface of the core lumber, wrapping around the core lumber with tail edge of a preceding side-member secured or connected to the inner side-face of the subsequent adjoining side-member at its head edge in a head-to-tail manner, to form the enclosure structure.
