Building an ottoman single bed flat-pack involves four main stages: assembling the headboard to the side rails, attaching the foot section to form the frame, fitting the slatted base panel with gas-lift arms attached, and connecting the base assembly into the frame. The gas-lift arm attachment stage requires both pieces to be held in alignment simultaneously, which is difficult for a single person, one person holds the base panel at the correct angle while the other fits and tightens the connections. Subsequent stages can be managed solo but proceed faster with two people. Total assembly time for two experienced flat-pack builders is typically 45 to 60 minutes. All fixings and an instruction guide are included with the DHS ottoman single bed.
