This is a Henredon coffee table, I believe it is Walnut, but it is pretty heavy, so it may be Mahogany. It measures 39" x 39" the diagonal is 55". It is a great table, BUT my old roommate never used coasters and therefore it has some bubbling marks on the top. I debated getting it fixed and Henredon recommended someone, but it doesn't really go with my style now anyway. You will have to fix this or perhaps just live with it as is. Look at the last two pictures to see what I mean. I live in the Los Angeles area so this is pickup only, BUT if you have means or desire to set up your own transportation for this piece you may pay for it and I can drop it at a shipping center or what not. Please let me know if you have any questions or desire any other pictures.
