Hard to know for sure where the problem is, but the chaise was received with a broken frame where the leg screws into the frame. This suggested inferior quality and we decided to return the sectional.
The chaise was delivered with the legs attached, while the sofa did not have the legs attached. This may have contributed to the problem.
We liked the looks of the sectional, though even if we had kept it, I am certain we would have ultimately been disappointed in the seating depth.
