This has to be one of my favorite rugs by far..surprisingly so. I just picked it out on a whim as something simple for the foyer. It's very plush and heavy so it works well for any room, but a foyer or kitchen is ideal as you would not have to worry over the backing. I don't feel the extra rubber for slipping is necessary at all. I got the 3 x 5 for my foyer and it's a great size and so plush. I didn't expect that or for it to be as striking as it is, it looks far more expensive..I love the variations of blue and sort of wish that i had chosen this for my kitchen, but I have another rug that I already bought for that. I was very surprised by how much I love this rug.
