Me too! My front room is used as my excersise room and I have 8x8 Cushion tiles, borders and corners as well. I have hard wood floors and was using puzzle mats with an 8x8 size carpet over that. When I invested in the Cushion Tiles I just put those on top of the puzzle mats and put the carpet on top of the Cushion tiles. I am very pleased with my purchase. I agree with dirtdiva, fabulous customer service.
