I have a 10 years old 88" Flexsteel sofa with 3 back cushions and 3 seat cushions. The seat cushions are still firm as are the back ones. I air the cushions standing them up and flip flop them once a month (my grandmother's trick). With the exception of a few pulls in the fabric due to grandchildren shoes, etc., it looks almost new. Want to redecorate and thought of buying another but considering a custom slipcover after reading comments
