I have been daydreaming of my very own full sized loft bed since my freshman year of college (~3yrs ago). During finals week, I decided that I could have it all: a dog, vanilla bean ice cream, AND the perfect bed for a pole vaulter. Note that I was only lacking one portion of my equation for happiness. I discovered the instructables website while searching for pictures of homemade beds. This instructable is a spin-off of ladyada's Pipe Dream Bed:http://www.instructables.com/id/Pipe-Dream-Bed/
I like that iron pipe gives an easy-to move, sturdy base material for this bed. Thumbs up, ladyada.
I used webbing to suspend my mattress/box spring in order to make the sleeping platform very swingy. If you want a more stable platform without the use of a box spring, please look at other instructables because I am only recording what I did. I haven't made a ladder for this yet and I will also be attaching a Navajo-style loom on one end. Having this tall bed creates space for reading/knitting/weaving/sewing/yoga in my room. It is also strong enough to do pull-ups and Bubkas and other strengthening exercises for pole vaulting.
