My husband and I invested in an expensive memory foam bed. It was great, but for one thing: with our covers we were too hot, then too cold, then too hot, etc. all night long. We didn't get much rest despite the super-comfortable mattress. Then we received this fabulous comforter. I put it in a 100% cotton duvet cover. We slept so soundly all night long we were thrilled! Wow, what a difference. We love it. It feels very luxurious and keeps our body temperatures even all night.
