Customize Your Chair

Choose from a wide variety of fabrics to customize your chair to your taste and get it shipped within 7 business days.

Consider adding Outlast technology so your body’s temperature stays regulated throughout the day, to keep you cool and comfortable. It works to control skin temperature and the impact of moisture. It proactively eliminates perspiration, instead of just wicking it away. It absorbs, stores, and releases excess body heat to maintain a consistent temperature.


Color Rendering

Computer monitors are not all calibrated equally and color reproduction on the Internet is not precise. Since it is not possible to guarantee our online colors will look the same on all computers, we do not guarantee that what you see accurately portrays the color of the actual product. However, we give you as many high-quality pictures as possible to give you the closest rendering.
