The sofa is packed with skill and cunning. However, the result is somewhat less than stable. It is a little rickety. There is a manufacturer caused problem---broken wood support due to a misplace bolt---which complicated my assembly. The arms of the sofa are uncomfortable. The upholstery bulges at the bends. Etc.

It's not the most wonderfully made sofa, but it serves its purpose

I suspect my sofa's specific problems are specific to my unit.
