What temperature do you like to sleep in?
The comforter you choose should be constructed so that it provides you with optimal insulation (this can mean keeping you comfy in the summer as well as the winter). Are you typically cold or warm when you sleep? A down comforter comes in a range of weights that define how warm the comforter will be. If you’re planning to keep the comforter on the bed all year, you’ll want a light- or mid-weight comforter that can be used year-round; if you will only use it during the winter, you may opt for a heavier weight comforter for maximum warmth. (Please note: Weight is not the same as fill, see the Details section for a fuller explanation.)
Do you have allergies?
Few people are actually allergic to down. Most likely, you are allergic to the dust, dirt and other allergens in the down. Look for allergy-free down comforters that are cleaned with a process that eliminates the impurities from the down and your worries, making them hypoallergenic.
What is a down alternative comforter?
This is a comforter filled with synthetic or natural filling materials that are almost as warming as down. If you are allergy-prone, alternative down, made from hypoallergenic materials is suited for you. Down alternative comforters are constructed similarly to down comforters, except the filling fibers are different. The type of insulation can range from synthetic microfibers to natural fibers such as cotton, wool or silk. Most down alternate comforter are machine washable and can be dried in a dryer.
Do you prefer quality?
It’s important to note that quality will be reflected in the material and construction of the comforter, so it’s a good idea to get the best quality you can. Look at down quality, thread counts in the cover fabric (better fabrics will protect the down inside and prevent down from escaping and wear better over time), and practical construction (e.g. baffle box to make sure the down won’t pool anywhere in the cover).
