I have researched many different artificial turf companies and found a company that I think really has there stuff together.  At least they have the most user friendly website with close up color pictures and specifications for their huge assortment of synthetic grass types.  Not only do they have the artificial turf specifications but they have all the testing sheets, MSDS sheets, Flammability Test, Lead Test, Certificate of Analysis, Water Permeability Test, CAD Details, Total and Face Weight Test, Tuft Bind, Grab Test, 15 Year manufacturer's warranty, Installation Guide, Artificial Grass Care and Maintenance.  Everything is right there on their website.  Not many companies are that forthright to put everything on their website so you don't have to call and ask.  When I did call Global Syn Turf they were very professional and knowledgeable.  They had their Orange County Turf Distributor call me for a free estimate.  They were a very friendly group of people and have very reasonable rates.  Their installation techniques were very detailed and the finished product was outstanding.  I highly recommend Global Syn Turf and their dealer installers.
