The 4 Foot Yard Swing seats two comfortably and is designed to be used with a freestanding A-frame rather than a ceiling or porch beam. It can go anywhere in the yard — under a tree, on a patio, or in an open lawn — without requiring a covered structure. The TC5048 ThermaFusion Cedar 4ft A-Frame is the matching frame; any compatible 4-foot swing frame also works.
Frame and arm construction uses solid Northern White Cedar logs with mortise and tenon joinery. Seat and back slats are thermally modified — a chemical-free heat treatment that significantly improves resistance to moisture, warping, and decay. Both materials are designed for year-round outdoor exposure without annual coatings or covers.
Cedar is a naturally weather-resistant species that performs outdoors without treatment. Left exposed, the frame will weather gradually to silver-grey; a penetrating oil maintains the original tone if preferred. The thermally modified slats will not check or warp seasonally. This is a low-maintenance swing built for long-term outdoor use.
About ThermaFusion Construction
ThermaFusion is Lakeland Mills’ hybrid outdoor furniture line, combining solid Northern White Cedar log frames with thermally modified wood slats. The cedar log frames use the same mortise and tenon joinery Lakeland Mills has built with since 1923 — real logs, real construction, made in Edmore, Michigan. The thermally modified slats undergo a chemical-free heat treatment that makes them significantly more resistant to moisture, warping, and decay than untreated wood. Both materials are designed for permanent outdoor installation without annual maintenance.
The cedar log frame components may develop small surface cracks as the wood acclimates to changes in temperature and humidity. This is a normal characteristic of solid cedar construction — not a defect — and does not affect structural integrity. The thermally modified slats will not develop this type of surface checking.

FAQ
- Does ThermaFusion furniture require sealing or finishing? The thermally modified slats require no sealant or finish — the thermal modification process provides superior resistance to moisture and decay. The cedar log frame can be left untreated as well; it will weather gradually to a silver-grey, or you can apply a penetrating oil to maintain the original tone.
- What is thermal modification and why does it matter? Thermal modification is a chemical-free heat treatment that permanently changes the cellular structure of the wood, making it significantly more resistant to moisture, warping, and decay. No preservatives or chemicals are involved — just heat.
- Can I leave ThermaFusion furniture outside year-round? Yes. Both the Northern White Cedar log frame and the thermally modified slats are designed for permanent outdoor exposure through all four seasons without requiring shelter or covers.
- Does the furniture come assembled? ThermaFusion furniture ships partially assembled with all hardware and detailed instructions included. Most pieces can be completed in under an hour.
