Bed frame/alternatives? I have a mattress (no box spring), which I simply lay on...

I have a mattress (no box spring), which I simply lay on the ground in a minute. I'm looking to elevate it somehow. Does anyone know some website or store where I can acquire reasonably-priced bed frames, or some cheap alternative to getting the mattress off the ground?

I'm a student, so, yeah, I don't own much money to spend on this.

Thanks!
Detailing??
Use plastic milk crates. Twin bed use 6 crates, Full bed use 9 crates, Queen bed use 12 crates. Don't forget to support the middle of the bed if your bed is bigger than a twin.

Answers:    What you need is a platform bed, they're made for only the mattress. They are also sold pretty inexpensively at many stores from Walmart to discount furniture stores. I activity to say if you own the skills and tools they would also not be difficult to make and you could probably find directions on-line.
