1. A replacement stair tread assembly comprising:

  • a core member, said core member having a thickness, a step wise depth, and a cross-wise width, said step-wise depth and said cross-wise width being greater than said thickness;

    said core member having a wood-based core matrix, said core matrix having a plurality of overlying layers, said matrix having substantially uniform properties of mechanical elasticity cross-wise, and having substantially uniform properties of mechanical elasticity stepwise;

    said matrix having an upper surface and an opposed lower surface;

    said core including at least a first wood veneer portion mounted to said upper surface of said core matrix, and a second wood veneer portion mounted to said lower surface of said core matrix, said first and second wood veneer portions lying in parallel planes;

    said core member having a quadrilateral form when viewed looking in a direction perpendicular to said plane of said first wood veneer portion;

    said core member having a periphery and an array of edge members mounted about said periphery such that said core matrix is concealed from view;

    said edge members being made of solid hardwood;

    said edge members including at least a first nosed edge member;

    said edge members including at least a first un-nosed edge member;

    said core having a first edge portion for mating engagement with said first un-nosed edge member, said first edge portion having a first profile machined along at least a first portion thereof;

    said first un-nosed edge member having a second profile machined therealong;

    said first and second profiles including out-of-plane features;

    said first and second profiles being mutually mating profiles;

    said first un-nosed edge member having a through thickness matching said core such that when said first and second profiles are mated said first un-nosed edge member mates flush with said first wood veneer portion of said core;

    said core having a second edge portion for mating engagement with said first nosed edge member, said second edge portion having a third profile;

    said first nosed edge member having a fourth profile machined therealong;

    said third and fourth profiles being mutually mating profiles such that when mated together said first nosing is flush with said first wood veneer portion of said core; and

    said nosing having an overall height greater than said thickness of said core.
