Great MASSIVE rug for the price. I wanted a light colored rug, but sit dogs and was concerned about dirt from tons of paws. There are light and dark spots of grey all over the rug making it perfect for hiding dirtiness. I was worried when I unrolled it because it looked like there were a whole bunch of gaps where the yellow lines meet up with the grey. I gave it some time and was relieved when the rug loosened up and the gaps disappeared. It's dense and soft making it comfy to lay on, and thick enough that I'm happy saving money and not buying a pad. It's also held up great to vacuuming so far. No complaints here!
