Ornate pieces, including sofas, chairs and table legs, were adorned with shells, scrolls, flowers, masks and other classical motifs.
Centuries-old wooden ships and buildings stand as a testament to the second life of the tree. Innovations have included high-speed machine wood preparation and joinery, spring upholstery, and the use of plywood and other modified-wood products. That is why the long direction of boards runs in the same direction as in the tree. The so-called through-tenon, with the tenon completely penetrating the mortise-bearing member, is the strongest of all. The less the finish is tampered with and the more repairs are entrusted to a conservative expert, the higher the value that the piece retains. Wedges which spread the tenon in the mortise are sometimes seen. 
In spite of these innovations, high quality hand-made furniture has always been available. The earliest archaeological examples all exhibit typical joinery - no matter where in the world they are found.
These have been used whenever the wood being available is not long enough, such as in house building. You can probably guess that a round mortise-and-tenon is not as strong. There are really only a few ways to successfully join wood, whether building a house or a chair.

Then the wax was buffed with coarsely woven linen and finally with a flannel or other soft cloth. Hand-made furniture was made the most efficient way possible, but it was still a labor-intensive and expensive craft. Basic construction techniques for hand-building still relied on mortise-and-tenon and dovetail joints, in which wood was cut to slot into adjacent pieces like a puzzle, to create a sturdy bond. The crown (leaves and branches) of the tree is supported by the stem, which must resist the force from the weight of the branches and leaves, as well as the loads imposed by wind, rain, and snow and ice. 
It is important that the tenon not slide out of the mortise, whether the joint is for furniture, house, or ship.
