I made this sofa and coffee table from 13 pallets I got from work. I used the plywood topped type as I didn’t want to any gaps on the seats. I stacked three on top of each other and fixed them together with screws. I then set another 3 in an L shape and then used another four pallets to make the back and sides. The draws can open for storage and also make a step to help our miniature dachshund get on the chair. The cushions are cast outs from our house and old sun lounger cushions covered by quilt covers.
I made the coffee table by stacking two regular pallets one on top of each other and fixed them together with screws again l then bought some casters and painted it with coloured varnish.
