This is a very comfortable small sized spiral stair. Most clients can go up half-way, turn around, and go down easily with very little experience or practice using a spiral staircase. The elbow room on this and any spiral stair can be much greater than the clear step space, as the elbow room is not limited by the handrail and the center pole. It is not uncommon to have a 4′-6″ diameter stair be one of the favorite ways to get to an attic, basement or back stair to a kitchen.
