The chairs are another variant of the chairs offered here on Amazon from different vendors in different variations. They differ mainly in the diameter of the circular base and the seat part. The gas spring is always the same. Incidentally, there is here on Amazon, an alternative long gas spring with which you can significantly increase these seats in height. For example, you can then make chairs for bar tables therefrom. Unfortunately, currently available only in black color.
