This bunk bed is very unique and there’s very few on the market that are full size. Most bunk beds and lofts are twin size only. As you can see in my pictures you can either use it with the two beds or keep the bottom open for your desk and computer. I really am sad to part with this because it took me so long to find. The only reason I am selling it is because we are moving into a larger house and the kids will have their own rooms. You will be satisfied as this is a great piece of furniture. Yes it fits adults as I have slept in the top bunk many times! I will include the top mattress board which I had to buy separately. Does not include either mattress as in the picture.
