The back pieces that slide down into the tracks so not fit , had to have someone else help me wiggle it in, needed a hammer but didn’t have one, went down as far as I could go. The box came arrived damaged, 4 days late as well. I put this together myself then had someone take the backs off because I couldn’t , they were stuck and had them manage to put them down as much as they would slide down in the track. They told me the track isn’t made right for the couch so they did what they could. Cute first time couch but definitely some errors. Very firm. The first couch picture is without being 24 hours to allow the cushions to fill out. The last few are 24 hours later.
