How do you link several mats together if you have a 8' x 24' space? I don't want to have uneven seams.

When installing these mats in a room, we recommend installing them in a brick pattern. The mats themselves do not interlock or link. You can use double-sided carpet tape or glue to adhere the mats to your subfloor, or you can use seam sealer glue to adhere the mats together.
