<p>So...do we need twin-xl bedding or will plain ol' twin suffice?</p>
<p>Twin will not work; you absolutely must have XL twin. Twin fitted sheets don't fit on XL twin beds.</p>
<p>My daughter had twin fitted sheets that work on an extra long bed (at a summer program at MIT). They are made for really deep mattresses, so they work with a little extra length.</p>
<p>Fitted twin sheets for really deep mattresses (16"+ deep), or the ones made of tee-shirt like material may work. But, the fitted XL sheet will defintely work without extra tugging. </p>
<p>Unfortunately, you usually need to buy XL sheets in sets...can't buy just the fitted sheet. Fortunately, Bed Bath and Beyond, Sears and others sell them for a decent price this time of year.</p>
<p>You can buy them for less than $20 at Bed Bath and Beyond I believe. That includes the fitted sheet, the non-fitted sheet, and a pillow case or two.</p>
