Mattresses have gotten more comfortable over the past decade, and in many cases, they have also gotten thicker as more layers of surface cushioning have been added. Mattress shoppers are often concerned that they won't be able to find sheets to fit these plush, extra-thick models. But fortunately, bed linens have adapted to these state-of- the-art mattresses and foundations. Sheets, comforters and mattress pads for these new, thicker mattresses are readily available, and often noted on packaging as compatible with "extra deep" mattresses or featuring "deep pocket" construction. In fact, bed linens today are offered in a wide range of sizes, from standard to extra deep, with specialty sizes designed for futons, day beds, flotation beds and even dorm mattresses. Whatever your choice, rest assured there are linens made to fit just right.
