The stable double-braced steel leg construction with large floor protectors is the soul of this robust and reliable introductory model. The height is adjustable in 15 mm intervals from 485 to 680 mm. The small footprint with a diameter of 540 mm makes the throne ideal when space is at a premium - and it is nonetheless stable.

The swivel feature can be adjusted from smooth to stiff using the easy-to-use wing nut.
