Scholar Crafts 180 Series Stack Chairs are an excellent choice for stackable seating. The contoured seats and backs are made of nearly indestructible 5/8" hard plastic. They are ergonomically designed to be comfortable and promote good posture. They also resist chipping, scratching and fading. Tubular-steel frames make these chairs extremely durable. The gooseneck design lets you place them upside down on tables or stack them to save space. Available in a variety of attractive seat colors to match your dcor, they come in a variety of popular seat heights and an adjustable-height model. Larger models are also available with sled bases that work particularly well on carpet.
