This wood & steel staircase is certainly a unique in that it has come to us deconstructed and seems like one that could be easily finagled to fit a plethora of spaces. Included are nine 12-3/8" x 32.5" mixed hardwood treads and three triangular shaped treads that we think make this a U-shaped staircase once fully assembled. However, because it goes together by simply stacking treads (there is no hard and fast structure it adheres to nor is there a center post like on a spiral stair) you could assemble this in a variety of different configurations with a turn wherever you so please. Included are six railing sections, an abundance of steel balusters, one 2-3/8" x 52-1/4" post, and a small box of caps and other hardware. Rise is variable, but the "post" mounted to each stair measures 15-3/4". Let us know how you fit this to your space by sending pictures to [email protected]!!
