This piece is so nice that you could use this Pallet Sectional Sofa indoors or out! This took six pallets to make, and you'd only need to add the cushions of your choice.
Make a Pallet Sectional Sofa for yourself:
First, I stacked two pallets on top of one another. I used spare blocks to create the sofa feet. I attached them together with screws. The armrests and side trim are all from deck boards. I mounted the seatbacks at a comfortable angle, trimming the side boards to fit. To stabilize the back, I used more deck boards and fitted them in. Each section can stand alone, but I like the look of them together. There are two sections with armrests, and the third is more of a chaise-style section.
