I got this comforter about two months ago, and I can honestly say I haven't had a bad sleep in it yet. It's the perfect equilibrium of cozy & cool! The lightweight microfibers prevent the material from getting too unbearably hot, but even with my bedroom ceiling fan at full blast (because that the best way to sleep, am I right?) I have never found myself waking up cold! I'm even considering purchasing it again in a Twin XL, so that I can take it back to school with me!
