High task chairs or stools often have footrest rings for providing support when feet are raised off the floor. Their drawback: If the seat height is adjusted, the distance to the ring will also change automatically. In conventional chair columns, the footrest rings are attached to the outer tube and cannot be adjusted. With the STAB-O-MAT FA, Stabilus has developed a column with which the ring is attached to a special telescopic intermediate tube moving through the stroke with the gas spring. This will always keep the distance between seat and star base the same, regardless of the height of the seat.

Advantages

• Foot ring position adjustable to the adjustment range of the gas spring
• Constant distance between seat and star base

Applications

• Swivel chairs with footrest rings
