This sturdy redwood table is built to withstand the wind. If you live in an area of high winds, you will appreciate the ability of this dining table to stay put. The base of the table is built in a square shape which contains a hollow space inside. The top can be easily removed to fill the inside chamber with sand bags or other heavy materials to weigh the table down. The table top and benches are made from 1 5/16″ thick, all heart, old growth redwood. Board pattern may vary from pictures shown. This reclaimed old growth redwood has a depth of color and fineness of grain unmatched by newer growth redwood.
