The four leg side chair and sled base lounge chair use innovative molding processes to deliver light, sturdy, highly cleanable, indoor/outdoor chairs ideal for corporate, healthcare, education, retail, restaurant and hospitality environments.

The chairs are easy to pick up and move around, and most importantly, comfortable. The stacking capability and upholstered seat option for both side and lounge and the ganging device for the side chair allow Spark to fill multi-functional seating needs in the office, incuding those for guest, conference, lounge, training, café and team activity areas.

The innovative processes used to make Spark are unique in the office furniture segment.

The process of co-injection molding for the Spark chairs allows fo the use of two materials - a prime grade, virgin, glass-filled polypropylene copolymer with liquid color for the outer layer and a glass-filled polypropylene copolymer in the core. Since the core material is completely encapsulated by the outer layer, it does not need to be prime grade, virgin material, which allows for the use of recycled material in the core.

The other innovative process that goes into the Spark chairs is the use of a small amount of foaming agent in the core material. As the plastic cools, the foaming agent expands, negating the plastic's tendency to shrink and form voids. This reduces sink marks, voids and shrinkage in the thick cross sections of the chairs. The co-injection process allows for the complete encapsulation of the foaming agent in the core of the part, eliminating swirling on the surface.
