I think we all know when you buy something like this it’s like rolling the dice on whether it will assemble right. I’ve bought a lot of furniture from Wayfair over the years and most has been okay to assemble. I suppose it was my time with this sofa. The metal pieces, where the screws insert, were basically at random for a vital portion of the base. 

Customer service could replace half if the other half was fine. It was not. Other option - get a shipping label. Can’t imagine how one would get a manufacturing grade vacuum sealed couch back in the box. 

If you would like to test your luck or capacity for suffering, I would recommend this sofa.
