I'm 71 years old and put these mats down in my garage. I placed them on my concrete floor infront of the washer and dryer. The mats interlock by pulling off the outside edging. The edging can be left on for straight finished edge. There were enough mats, with 2 packs, to run them between my racks, to the outside and inside kitchen doors. Now, when I bring the wet dog in, we don't slip on wet concrete! Same with wet boots and clothes from working in the orchard and garden. I love the look, comfort and security these mats provide. Well worth the money!
