The AAA Playground Expanded Metal Double Post Picnic Table is a wonderful outdoor dining table with a simple and robust design that is easy to install on concrete, grass, asphalt, and many other types of surfaces. It has a fortified design with strong square columns on each side that support the table and seats. This clears the entire center of the table for leg space, making it easy to move around on the bench to make space for others. And with six and eight-foot lengths to choose from, you can select a model that has the legroom area you require. The columned framework of the two pedestals is secured to the ground with either surface or in-ground mounting hardware.
