I bought one and then one more, size of 8 x 10, to cover my entire living room. We have a puppy and need to protect the floor but also be able to wash the rug. 
I love this rug! The colors are very nice, it is thick enough and has a rubber lining to stay flat. I was worried if it would be too big for my washing machine, but it got washed without any problem. I did not use a drier and instead air dried it before putting back on the floor - colors stayed bright, and all the dirty paw prints are gone.
