^ No, don't do that.
From the Residential Hall rules here:
http://www.campuslife.cornell.edu/ca...-09-final2.pdf
"Residents are not allowed to use home made or purchased lofting units. Any found in
non-compliance will be charged for the removal and are subject to disciplinary action. If
a resident wishes to have their bed lofted, it must be done via a work request through
Campus Life Facilities staff. Lofting requests where applicable are accepted for 30 days
after opening or until supplies run out, whichever comes first."
And don't use cinderblocks - they charge $25/block to remove them lol.
I would like to have a lofted bed though
