I just went and got a couple packages of 'sheet suspenders' from Walmart. (Not all employees know what you're talking about when you ask for them). They're elastic bands with suspender type latches. Gather up the sheet at the corners and add the suspenders to cinch up the slack.
I once paid $60 (regular price $120) for a fitted sheet with high thread count and 360 degree elastic sewn into the edge for my RV. AND IT DID NOT WORK. The sheet was for a actual Queen sized mattress and a RV mattress is slightly smaller! Sleeping on it for 30 minutes would bring the sheet up off the mattress. GAH!
So that's when I added the suspenders.

I'm not sure what Loft bed is, so this may not be helpful. We have an air bed in our Winnebago Aspect ... a short queen. I bought our mattress pad from the site below and love it. It fits perfectly and is very nice quality. Maybe they have sheets that will work for you.
