We purchased a Henredon sectional and after 1.5 months the C grade fabric started separating from the seam, there was a line through a cushion and the hardware that kept the pieces together completely fell out. This was our first purchase of upholstery after 18 years so we do not have much experience. I'm wondering if anyone is familiar enough with the fabric grades within the Henredon line and if this was just bad luck? The grade C's tend to be 100% poly. Good? Bad? The company will be replacing the piece but we have decided to not replace it with another sectional. I was thinking of going up a few in the alphabet grades but not sure if I have to...? Our family room is 21'7" x 18", so a good size but odd in shape. Wondering if I should go with a 91" sofa and a 68" loveseat or 2 88" sofas. We also have a current odd chair in the room as well. Thank you!
