Gliders come in a variety of types and styles. The most common type of glider furniture is a bench with a backrest. These typically are 4,5 and 6 feet in length. They hold 2 adults comfortably and the larger models will seat more. Most gliders are made of wood but other materials are availble such as recycled plastic and metals.
Gliders styles and types also include vertical and horizontal back rests, flat, curved and ornamental tops. The gliders have a hinge and swing mechanism that allows the glider to slowly move back and forth. The movement is more level to the floor as opposed to a rocker type motion. This motion varies from glider to glider. I would recommend a glider that has a longer motion rather than a shorter motion. The longer the motion forward and backward, the more comfortable ride and less jerkyness.
