Well Here are a few words that are close to what your asking. Bed Cover would be called "Quilt" or "Duvet" or "Comforter" (Duvet is pronounced "do vay" in english letters) Most people would accept Comforter. The Easiest word that people ALWAYS use in america is "Blanket" "I'm cold, can you get me a blanket" "I need a blanket" "Where's my blanket" "You look warm and cozy under that blanket" If you mean clothes that you wear on your self to bed than you may say Pajamas The translation i found online says its a quilt. which is usually something grandma made that is like patched together. Quilts might look sorta like a Checker board but more colorful Where comforter can look like anything, but usually is a solid color or has a patern but still has a "sewn" design. (I would just use blanket) Pronounced "blane kit" or "Blain kit" or "Blank it" (it is only pronounced one way)

It's quilted cover

it should be quilt,and it can be also used as a verb.
