Here in England we used pressure-treated timber wood with preservatives into the timber to protect against fungal & insect attack enhancing protection. Treating timber wood helps extend the life of this construction material, reducing the levels of upkeep and repair needed. Another important tip for you is to choose the wood that is completely straight, so I always go to pick mine, I never trusted ask for delivery when woods is involve, they can send any random and not completely straight, hope this help. Ana suggested to use a water sealer made by thompson apparently is very nice and water proof to protect the wood

Great simple and easy design. I tweaked it a little to make 2 smaller love seats to fit under pergola(4 feet seating). I'll definitely be using some of your plans as starting points in future. I had a harder time finding cost effective cushions than actually building pieces. Love em and thank you!!!

Hi. Just wanted to know if using pressure treated 2x4s for the seat frame and seat boards to cut the cost would be a bad idea. (They will be hidden hnder the seat cushions). Thanks
