I removed our “L” shaped sofa a couple of years back. It wound up only having 1 hold-down screw in the floor (maybe 2) and a couple of screws in a side wall. I started by removing obvious screws that held it in place and checking for looseness. I got it mostly detached from the floor and wall, then started looking for screws holding the pieces together. The backs in the main sofa section were held in place by a clip on both sides and releasing the clips, pulling up removed them. The “L” piece came apart in pieces pretty easy as well. Everything went out thru the door. Take your time, these things are designed to be quick and simple to install so removal shouldn’t require any rocket science.
This is part way during the install, the slide-on attachments for the seat-backs are visible. Initially I did not secure it to the floor but a couple of trips suggested it’d be a good thing to do.
