I'm interested in buying a Flexsteel Bexley sofa. How much difference is there between the HHH rating and MMM rating for wearability? I wanted to buy an HHH fabric, but found the color I wanted in an MMM. Can you explain the grading of fabrics also? I just got home from a local furniture store and found your forum for the first time. What an education! I cut and pasted the furniture 101 info you gave on another site and hope to refer to it often, before I buy. Thanks so much!
