<p>How thick are the mattresses in the freshman dorms? I bought a 3 inch thick mattress topper that is amazing so i really want to use it, but I was wondering if the sheets I bought that fit 13inch thick mattresses will fit on both the duke mattress and the one I bought or if I need to buy deeper pocketed sheets. </p>
<p>Also how long are the twin mattresses, because my mattress topper is twin size, and while I don't need the x-long size because I'm not that tall, do you think that will be awkward? The mattress pad comes in x-long but its more expensive and also currently out of stock. Should I wait til it comes back in stock and spend the extra money or does it really not matter?</p>
<p>I think that if you would fit on a twin mattress topper that you'd be fine. The beds are twin-XL. Can't really help you with the thickness, though.</p>
<p>Yes, a twin mattress topper should be totally fine, and I wouldn't worry about the thickness. I had 3 inch thick memory foam on top of my bed and just had regular XL sheets, which was totally fine. My sheets fit perfectly with room to spare.</p>
<p>Has anyone been able to use regular twin sheets (not XL) on the beds at Duke? I've heard that the mattresses are thin and even with an egg crate a regular twin fitted sheet will be ok. But I'd like to hear from others who have tried it.</p>
<p>Nope, nope, nope. Don't do it. Twin XL -- they stress that you need that size for a reason. It's not about how thick the mattress is -- regular sheets just won't stretch far enough down because the mattresses are too long.</p>
<p>EDITED because I have the maturity level of a 5 year old and I just couldn't leave "It's not about the thickness, it's about the length" up on here like I originally wrote.</p>
