The Keilhauer Sguig chair, released in 2006, has a glass-filled nylon polypropylene back that supports the spine from the T1 to L5 vertebrae. Sguig was designed by Eoos with gender-specific ergonomics in mind: the chair accommodates the seating patterns of both men (who tend to lean back) and women (who tend to pitch forward). Available in three electro-welded back patterns, the chair features polyester textiles that come in 12 colors. Arms, back height, tilt lock, and seat pan are adjustable. keilhauer.com
