One of the most important but underestimated parts of a chair is the gas spring.
We only use class 4 gas springs for our chairs (usually only class 2 or 3 gas springs are used).
These gas springs are extremely strong, long lasting and support up to 180 kg (400 pounds).
Freely adjustable height of +/- ca. 10cm (gas spring MEDIUM / LARGE); +/- 5 cm (gas spring SMALL)
Please note: The plastic cover for the gas spring is not included.
