"Handcrafted in Edmore, Michigan, by Lakeland Mills since 1923, the Lakeland Mills ThermaFusion Cedar Log 4' Porch Swing earns its place by being built with quality. This outdoor swing combines a solid Northern White Cedar log frame with thermally modified wood seat and back slats. Thermal modification is a chemical-free heat treatment that permanently changes the cellular structure of the slats, making them more resistant to moisture, warping, and decay than standard wood. The contoured slats support both the seat and back for lasting comfort during long evenings of swinging. The cedar frame and thermally modified slats are designed to remain outdoors year-round. Mounting hardware is not included. 18""H x 48""W x 21""D. Manufacturer model #: TC5448. Solid Northern White Cedar log frame Thermally modified wood seat and back slats Thermally modified slats resist moisture, warping, and decay Made for permanent outdoor use"
