The widest Indoor green available without a seam is 4’ wide. To make our 8’ wide mats, we seam together two 4’ wide mats, leaving a seam in the middle of the green. In the beginning you will notice the seam. Based on customer feedback, the seam becomes un-noticeable after it is used for a while. Over time, walking on the surface will blend the seam together. There is a break-in period from a few days to a few weeks depending on how much use your green is getting. Walking on the green, particularly over the seamed area, speeds up this break-in process.
