What is an outdoor glider? What defines a glider from other types of moving chairs is that they remain stationary and use a smooth swaying mechanism to allow the seat to glide back and forth. They come in various styles and colors. Most have metal frames and upholstery, synthetic rattan, or fabric backing. There are two-seat bench style units. There are two-seat units that have separate seats but are connected by a convenient table in-between the seats. Outsunny gliders make a fantastic addition to your porch, backyard, patio or garden area.
