One of the most cherished designs in GUBI's collection, the Bat, has been given a functional makeover with the addition of adjustment mechanism that takes them to new heights of versatility. The chair is set on a black four-star swivel base in steel and aluminum—an elegant contrast to the five-star base common to commercial furniture. The base is available with either fixed gliders or castors, depending on whether the chair is to be used in one place or a dynamic work setting. The design is hugely variable in expression, with veneer and plastic material variants, and a wide range of upholstery options, fabrics, and colors available—from soft velvet to smooth leather—allowing them to blend easily into any interior.
