<p>In engineering terms, when you run out of space in two dimensions, you must use the third dimension. Alot.</p>
<p>Can you cut memory foam in half? My roommate and I are thinking of buying a king from overstock.com and cutting it in half.</p>
<p>Intrestingly enough, it looks like most of overstock's memory foam toppers cost the same for a twin and for a king, so yeah, you should get the big one. If for whatever reason you couldn't cut it you could still fold it in half and get double, I guess.</p>
<p>chuy: If you're actually trying to <em>sleep</em> with someone (in the literal sense of the word), then three dimensions is even worse, haha.</p>
<p>get a tempurpedic pad....
i will be parting with my queen size tempurpedic 9" mattress soon :(</p>
<p>too expensive. i'm probably just going to do the fiberbed and egg crate, simply because its about a total of 6 inches (3" fiberbed, ~3" egg crate) of loft and it's still on the cheaper side. You can't get 6" of memory foam for $80, and it just seems like a waste to get a fiberbed and then a whopping inch of foam for more than the fiberbed+egg crate.</p>
<p>Oh it can be done eph, and all that space between you and the ceiling can still be used. Get creative! haha. </p>
<p>Shoebox: You COULD get a 2 inch memory foam King for $80 and then fold it over, giving you four inches of memory foam. I think you'd come just a little short of covering the whole bed, but it's still beat the fiberbed, I believe.</p>
<p>Shoebox: I don't know if it would fully cover two twins, but memory foam CAN be cut pretty easily.</p>
<p>If you get a King (76x80) and cut it in half you'll have 2 38x80 pieces. A twin extra long (most college beds are this size) is 39x80. You'll be short an inch, but that isn't that bad. Cali kings are longer but not as wide.</p>
<p>That's what I was planning to do. But it seems like a waste to put such expensive foam under a fiberbed. I think an eggcrate would be better because its cheaper, I dont care if I throw it away at the end of the year, and it will give me more lift for a lesser price. I did fine with the eggC last year, so I only need a bit more. 3" fiberbed plus the eggC and some comfy pillows will probably be heaven. If it sucks in the long run, it'll only be $15 down the drain and i'll just buy another eggC and have two plus the fiberbed. If the memory foam sucks, i'm out $40-$80.</p>
