Having a modular 5 piece is great to get it down to the basement where it would fit down the stairs.   At first this sofa seemed good.   however after only 5 months, the backs are starting to fall off the seat.  I have to keep inserting them all the time.  there is one piece that no longer even fits in the seat and the back is now not straight anymore.   Also the locking clasps to keep the sectional together is really getting annoying now.   The sectional pieces keep moving back and forth and not staying in line with the rest of the sofa.    I also find that the seats are quite hard and I thought over time they would soften up, but the sofa is not that comfortable.  lots of improvement needed for this sectional.
