Hi there, I recently bought a new sofa and a couple of wall-mounted shelves and could use some help with assembly. The sofa requires connecting the base and arms, attaching legs, and ensuring everything is secured properly. I also need guidance aligning and mounting two lightweight shelves on a plaster wall, with appropriate wall plugs and screws. I’m aiming for a clean, level finish and would appreciate someone careful with instructions and diagrams. If you have a drill and level, that would be great. I’m flexible on the start time, but would prefer to finish by early afternoon.
