I work on the rigs here in Alberta and am constantly lifting things. It's a young man's game, and I'm not that young any more. Anyway, I bought a memory foam mattress from NovosBed and it's difficult to express how happy I am with the purchase. They're WAY cheaper than Tempur-Pedic (70% less I think) and if you've got back pain like mine you'll be amazed at the relief it provides. I'd recommend it to anyone for sure - http://www.novosbed.com. I'm not sure about getting insurance to pay for it though...
