The exclusive chairs by noblechairs are definitely in a class of their own and combine noble design with the highest quality materials and extremely precise workmanship. During purely mechanical production, meticulous care is taken to ensure that the latest industry standards and high quality standards are met. The noblechairs chairs of the EPIC series are designed for the lowest level of the standard gas pressure spring for users with a size of approx. 1.80 m. The height adjustment of up to 5 to 6 cm makes the chair ideal for even larger people. For users under 1.80 m, however, offers a shorter gas spring, as the feet reach the ground otherwise not comfortable. With this very short version of the gas spring, which is 3 centimeters shorter than the original, even \"smaller\" users can sit comfortably on a noblechairs chair. Despite the shorter length, the extremely short gas spring is approved for a load of up to 180 kg and allows a height adjustment of the seat up to 10 cm. We recommend disassembling the plastic cover of the gas spring at its lowest position so that the plastic protective cap will not be damaged. Note: After installing this shorter gas spring, the original plastic covers can not be used. Technical details:amount: 1Color: BlackCompatibility: noblechairs EPIC, HERO & ICON series
