Got a disassembled futon at my place – and it’s assembly was quite a project. Took me about two hours to get it together. Photus phollow (wife took camera away to click our daughter, so the trail is a little incomplete).
nuts and bolts
left frame and transmission
plan on board
frames attached to stretchers (progress 1 hr later)
transmission attached (another ½ hr later)
attaching the seat/back frames and rolling out the pad - final outcome
