I think the garage carpet is a fairly recent option (or part of the S5 package perhaps). Ours has never been unrolled though we did get a piece of low cost indoor-outdoor carpet at Lowes that we use instead. We found that a couple smaller pieces are easier to contend with than one large one. Smaller pieces made it easier to locate and cut the holes for the table posts and if the carpet gets too dirty, it's easily replaced.
