    Abstract: A tread member for a staircase is preassembled from strips of wood material which are laminated to one another by adhesive to form a panel with an integral nosing member attached thereto. The preassembled tread member need only be cut to width and length for installation on an existing tread of a staircase for covering a staircase with hardwood floor material more quickly and with a better finished result as compared to traditional methods in which individual tongue and groove strips of wood material are attached to the staircase. A riser member comprises a panel formed of strips of wood material laminated together is also provided for covering the existing risers spanning between the adjacent treads of the staircase.
