I bought this to jump on while doing Insanity. I could feel the floor when jumping on it. I sent it back and got a big 2" thick foam mat from We Sell Mats. I think it's listed as a tumbling mat. It was MUCH better, exactly what I was looking for. This might be ok for someone lying down on it, but if you want something this squishy, maybe you should do your exercises on a bed.
