in 1999 we bought a flex-steel sectional. It had a sleeper and two recliners on the ends. It has a big pillow back design but it's attached. It is now in our basement. The cushions have held up, seats, everything. It was a wonderful couch. Hubby decided we needed a new couch, he constantly fell asleep on it, would mow the lawn and come in and sit down on it (sweaty and nasty) so it really needed to be reupholstered. So we went shopping. Ended up at Sofa Select. Bought what appeared to be a nice set, with the attached pillow back. These have pulled away from the sofa. They still look nice after 3 years but definitely not the quality of the flex-steel. When I decide to replace these (sooner rather than later), I will find where they are selling flex-steel around here. We bought it from a flex-steel store which is no longer there, but the brand is still being sold.
(ETA: I have three boys, two dogs and had one cat. The sectional went through moves to three houses and from my youngest being a toddler until three years ago. Now they see the boys and all their friends using them for sleep overs and video-gaming. It had seen a lot of abuse. Whereas the newer couch has seen less and did not hold up as well.)
Also, the family I am babysitting for have Smith Brothers of Indiana. I do like their couches. They seem to pretty sturdy but very comfortable. The dad is very tall and the couches are deep so he can sit comfortably. I'm short (5'2") and I don't feel like Alice.
