Posted under black futon

Im trying to save lots of space in my room, so i am wondering if it is possible to take this bunk bed:

and make it able to have NO futon so i can put my homework desk under it.

this is what i would want it to be like (just no additional things) so it would be only the top bunk and the stands.

any advice would be EXCELLENT.
thanks =)

The Question is "Do YOU Have Any EXPERIENCE as a Metalworker?" Without a welding machine, grinders, paint, and metal stock, I DON"T THINK SO.
