We love this comforter! It is light weight but super warm without over heating you. Temp has been just a bit below zero here and we have been nice and toasty. It washes well in my front loader machine on delicate cycle but it does take forever to dry, because you have to dry on low but make sure its really dry because its down. No fluff has come out. I think the oversized king would not cover a king mattress cause it barely fits our regular queen bed with only a few extra inches to hang over on either side. We will have to wait and see how it will do in an Arizona summer.
