Whippet Chair by Hugh Thomas
Via Ron Beck Design
Hugh is an Australian designer who has this chair published on Coroflot as well:
The “Whippet Chair” draws inspiration from the breed of dog of which its name is derived. With its slender atheletic styling the chair is designed for short term seating environments. The seat is ergonomically inspired by a classic tractor seat form, giving the user maximum comfort without encouraging prolonged use (This is important in environments such as cafes and coffee shops with a fast turnover of patrons).
