Looks much better in person, I purchased this rug for use under my coffee table, so no padding was required.  The edges uncurled in a day, but after 5 days there are still a few small ripples that I'm sure will flatten in a few more days time.  There is a noticeable chemical order when you open the packaging that can be overpowering in a small closed up room, so I suggest opening outside and air out if you can for a day or two.  The odor dissipates and after a five days is barely there - I come and go often so I notice a faint odor upon return.  These rugs are super soft and like I said much prettier in person.

Pros: Super value for the 3 pieces!  Soft and really pretty!
Cons: Odor and may require padding if you use in a slippery spot.
