The Saturn Series is the biggest racing chair we have in stock at the moment. It has a bigger frame than Mercury and Pluto, thus the seat base is wider. A combination of PVC and PU leather is used as the core material.
The Mercury Series uses PVC leather as the core material. It is slightly smaller than Saturn.
The Pluto Series is the smallest sized racing chair we have at the moment. Breathable fabric is used as the core material.
