All of our listed dimensions are outside dimensions of the product (the amount of room they will take up) and are approximate.  With rustic furniture dimensions will vary from piece to piece.  

A common question we are asked is if a standard mattress may be used on our beds.  The answer is Yes.  If you choose a twin bed a twin mattress will fit, if you choose a queen bed a queen mattress will fit, etc. etc.

Twin over Queen or Full over Queen Bunk Beds will use an extra long twin or an extra log full/double mattress on the top bunk due to the queen mattress being longer.  

Please feel free to contact us with any questions/comments regarding our dimensions.
