One of the most friendly looking and simply designed lounge chairs around. The Knoll Spark Stacking Lounge Chair adds warmth to whatever space it’s placed in with its rounded edges and vibrant color choices. With a frame made from Polypropylene reinforced with Glass, the chair is light in both its weight and its presentation. The chair also features a seat pad that comes in several different KnollTextiles, providing comfort and another opportunity for visual customization. It is also stackable up to 6 units high (10 units high if stacked with the Spark Dolly), making it easy to save space. If you remove the seat pad, the chair can be suitable for use outdoors.
