Very pleased with mats. Had them for over two months and they hold up very well. I use them in my living room and den for my children. They like to roll and jump and run around. These mats are also great when we do our Wii fit workouts. Makes running in place a lot easier on the legs (I weigh 170 pounds). They look very nice and the "interlocking" holds exceptionally well. I also have the 1/2 inch mats but these are superior if cushioning is what you are after (also, since these are 1.1 inches thick the interlocking is more secure).*UPDATE (March 2012): It's been slightly over a year and these mats are holding up really well. They interlock well and still look really nice. One warning only, it you have a cat it will like to use them as a cat scratcher. Better these mats then the couch.

I was a bit leery about ordering the 1.1" due to the price. But my husband's take was that if we're not spending money on a gym membership, we should go high quality so we'd want to use our workout space. I'm glad we did! We put these in our basement (concrete floors) and we can both do plyo, sit-ups, push ups comfortably on them. We aren't planning on putting the elliptical or spin bike on them but do have a weight rack as well as rebounder on them and it works well. It provides a comfortable and nice looking space and well worth the money!
