Thanks for the inquiry.
I am sorry to tell but the beds of the Atlas Triple Sleeper cannot be separated into 2 beds as the posts are straight supporting top and bottom bunk. Unfortunately none of our suppliers has a Metal Triple Sleeper that splits into 2 beds, it's only the Wooden Triple Sleeper ones which can be such as the Pine Triple Bunk Bed - Antique Natural - http://www.lovefurniture.ie/bedroom/bunk-beds/pine-triple-bunk-bed-antique-natural or the Mars Triple Sleeper - http://www.lovefurniture.ie/bedroom/bunk-beds/mars-triple-sleeper-whitewash-clearance
Regarding the mattress, we have our affordable and best selling Tara 4'6ft Double Mattress available which fits great for bottom bunks http://www.lovefurniture.ie/bedroom/mattresses/sprung-mattresses/tara-mattress/tara-46ft-double-mattress
