The Sleep Philosophy® down alternative comforter collection features 3M™ Thinsulate™ Featherless Insulation-600 Fill Power, a kinder alternative to natural down. This revolutionary, loose fill-down alternative mimics or surpasses the performance of natural down in Fill Power, loft and overall performance. Made of durable, lightweight polyester fibers, 3M™ Thinsulate™ Featherless Insulation provides warmth without a single feather. The Sleep Philosophy® down alternative comforter collection features a silky-soft 300 thread count, 100-percent cotton sateen cover. The comforters have sewn through box quilting so that the down-alternative fill doesn’t bunch or shift. Four corner loops on the comforter can be tied to help secure it within a duvet cover. The filling is also hypoallergenic so you’ll have a comfortable "sneeze-free" night’s sleep. It’s also machine washable for easy care. This comforter is also OEKO-TEX certified, meaning it does not contain any harmful substances or chemicals, ensuring quality comfort and wellness. Items in the set may come in a rolled or compressed packaging, which will need to be fluffed up or steam ironed before use to remove wrinkles. A great night's sleep never goes out of style. That’s our Sleep Philosophy.
