Yes, there is cork under these coasters - all but 1/4" from the edge of the stone.

Yes, the backs of the coasters are cork. I love these Thirstystones. This is my second set.

It is nice to have coaster under glass of water regardless. Personally, I used it as decor because its cheap made and breaks easily (it broke when our cat (small) climbed on it) so No I do not think you absolutely need coaster.

4 inch Square coaster made from pulp board *Medium Weight: Approx. 1.4 mm *Coasters are 100% biodegradable and recyclable *Color is white Bar: Great for the small or home bar. These are plain (blank) coasters in a medium weight. These are just like the paper coasters in your favorite bar except there is no printing.

No but there is some condensation that develops between the bottom of the glass and the TOP of the coaster causing it to the glass when you pick it up. This can happen with any coaster in my experience. These work very well for wine bottles on a table, as well.

The back is somewhat finished. Parts of the back are pressed wood/cardboard, but they do match the finish.

It is a black marble top with a dark grey hue, the best pic I could find was here: http://www.bing.com/images/search?q=coaster+marble+bar&qpvt=coaster+marble+bar&FORM=IGRE&id=97A4B70E0775FC8F4C7331316FC6448FDE8F180B&selectedIndex=0#view=detail&id=3E6A0789E4C07D7160C5BEBA26F584F79AE6638D&selectedIndex=46

This is a Coaster. Not sure but may be a lazy boy product. Top quality, firm and easy to put together. Very nice fabric that looks like it will wear well. I I use it as an accent in my bedroom so doesn't get a lot of use.. I love this chair and can't believe the price I paid for this quality product.

The table feels like it could be coated and it's easy to clean, but I'm not 100% sure that it has protective coating; I think you'd have to contact the company. I haven't wanted to take the chance so we use coasters :) However, we've had the table now for over a year, and not *every* glass has been on a coaster, and we don't have any visible watermarks.

The cork is quite hard but it is tacky, giving you a good grip if your hands are sweaty. It is natural cork and not synthetic. It has metal tips on the ends of the grip to keep it from getting chewed up if the bike falls over. As far as hardness, there is no give in the cork. Hope this helps

I think these are the coasters that are shown in the holder...they're the coasters that I use in the holder: Thirstystone Sandstone Cinnabar Coasters

It is more absorbant than say a plastic coaster but I would not say that it is as absorbant as a cork coaster. It looks nice and does absorb well but it will get saturated with water much faster than a cork coaster.

It is cheap. The back is a piece of cardboard make to look like oak. I was surprised, but overall it didn't look too bad, and is much more fragile that I had expected.

The back is particle board made of wood. Like masonite but flimsier. Don't stand on it!

I don't know what kind of wood because I never received the item. The marble broke in transit. So I purchased a different one from Amazon that I truly love. An looks way way expensive than the Coaster Bar.
