Coverlet
A coverlet is a bedcovering with sides that hang down a few inches past the box spring, but don’t touch the floor. A coverlet can be tucked in or left untucked if edged with decorative trim. Luxury coverlets can be layered directly over a flat sheet or over a blanket. It may sometimes resemble a quilt, but unlike a quilt, which is comprised of several layers, a coverlet is just one layer of fabric woven in such a way that mimics the quilting technique. 

 Another misconception about microfiber sheets is that they make you sweat.  While it's true that microfiber isn't as breathable as natural fibers like cotton, high-quality microfiber sheets are designed to wick away moisture and regulate body temperature.  Look for microfiber sheets with moisture-wicking properties to ensure a comfortable, sweat-free sleep experience.

A duvet is similar to a comforter except it requires the use of a duvet cover, where a comforter does not. Typically, a duvet is solid white and stuffed with down or a down alternative.
