I learned a lot about artificial grass in the last 6 months.  I have done extensive research on synthetic grass before I had my yard installed 2 months ago.  There is so much information on the internet about artificial turf companies and you have to be careful when navigating the truth.  The most helpful company with the most informative website for me was Global Syn Turf.  They give you all the information upfront with no smoke and mirrors or lies.   My artificial turf installation came with a 15 year manufacturer's product warranty and from what I found there it is hard to find the actual manufacturer of the artificial turf.  I learned the artificial grass has a 20 to 25 year life expectancy and a 15 year warranty.  I am glad I found Global Syn Turf and their national affiliate network.
