Abstract: A stair system that uses angled brackets to form risers. The brackets are attached to wooden or metal boards. These boards are standard dimensional lumber. The ends of the boards must be cut to position them to support the stair, but no other cutting is required. The angled brackets have an upper section, and a lower leg portion that extends at a right angle to the upper portion. Both the upper and lower portions have flanges on them. The flanges support a tread. The treads fit over the brackets to form the actual stair. The treads are designed to receive carpeting to match the desired decor of the building in which the stair is placed. The treads are also designed to permit a mixed wood and carpet design. Wood flooring may also be used by placing the wood directly onto the brackets.
