Can't tell without a photo of the room.

It is done. Some people don't like it. Also depends on the wall-to-wall and the rug you plan to use.

rug on top of carpet is just a no-no :)

In a large room, a rug on top of the carpet can help define the space. For the dinning room, you need to make sure the dinning table and chairs are not sinking into the rug/carpet layers so that it looks odd or pulling out chairs is difficult. It will depend on the particular carpet and area rug you are using.

i suppose.... but i wouldnt :)

Thanks guys and here is a pic of the dining room and the area rug I plan to use. It's 8 by 10 in size so plz suggest.

I think it will look all right. If you already have the rug, I'd go ahead and try it, but if that table is more than 6' long, the rug will be too small.

It could be one foot longer on the ends, but that's nitpicking. Unless you can exchange it for a longer one, I'd probably use it, depending on what else you plan to do with the room.

Well! Was planning to buy a buffet table but actually got this on Craigslist for 200 bucks and have small kids so for now I think we r good with this one:)

I like it.
