The Eastlake style, which developed after English architect Charles Eastlake published his book, Hints on Household Taste, typically featured simple, rectilinear construction, with no excessive curves. Furniture was generally of walnut, with panels of slats or lath, chamfered and serrated edges, chip carving, incised lines, and sparse inlaid details. Ebonized wood was featured in some pieces. Other woods used included mahogany, cherry, oak, ash, maple, etc. Legs, supports and posts were either turned or square, and were straight and heavy. Supporting leg sections were often flat. Tile ornament, finials and wrought metal mounts were other details used in Eastlake style furniture. Small brackets, shelves and carvings became popular during this time.
