I have been trying to find information on Mathews & Parlo Style SPR 619 Color 221. Long story short, a discount carpet place has it in stock. When I try to google "SPR619 style or 221 Color" nothing comes back on it at all. Only thing that really seems to come back is stay away from M&P. We are being told its a Nylon carpet but cant back that up except word of mouth from salesman. We really like the look and feel of the carpet. It has a felt back but the glue pattern on the back isn't smaller/tighter. Its your standard square look. Looking for some advice on this carpet. Money isn't an object we just want the best overall "wear pattern" resistant carpet.
