Dolle Calgary Spiral Staircase Black

The Calgary staircase from DOLLE is a characteristic spiral staircase that  combines design and comfort at an attractive, affordable price. It solves the requirement for a link between floors with very little space allowing you to utilise an area on the next floor taking up minimal floor area. The staircase is black and comes complete with 11 steps and a landing platform in beech multiplex. The pitch height can be adjusted with spacer rings from 20.4 to 23.4 cm depending on floor height.
