Bit overpriced - thick understandably for reliability. But because it is stored at the store in a cylinder its difficult to lay out flat. And it is somewhat bumpy to roll over. We currently have it on industrial/commercial carpeting.
It's rectangular that's what I like most about this mat. I got rid of my rug and replaced with is hardwood mat for easy cleaning to minimize fleas(I have pets)and dust mites accumulation.
