We Absolutely love this rug! It’s so thick and plush. We did not place an underlay and it feels amazing JuST as it is. I’m not sure how “true to size” it is-we ordered the 7’10”x9’10”so I’ll have to properly measure and see. Otherwise the wrinkles came out within the day, it arrived a day early which was a bonus, it fits well in the tv room, true to color it’s nearly an exact match. 
I have already and will continue to recommend this rug and would absolutely purchase again. 
Thanks Wayfair!
