The Up 2000 series is a collection of seating designed by Gaetano Pesce for B&B Italia. The UP 1 is a round-shaped seat constructed from flexible, cold-pressed Bayfit foam and comes fully upholstered in a choice of fabrics. The bottom is made of 100% jute fabric. See UP 2 for a smaller version of the chair.

The seats in the series, thanks to their unique shapes, are an artistic addition to the interior. UP 1 can be combined with several models from the same series. Thanks to the UP 5_6, the Up 2000 series has achieved iconic status and is as interesting today as when it was first introduced in the late 1960s.
