When you decide to purchase a down comforter you are selecting the warmest, most luxurious and comfortable way to sleep. Possibly you want to be warmer in bed, feel luxurious or just sleep better. There are a lot of down comforters out there, many without any real information for the consumer to make an educated purchase. Considering you spend 1/3 of your life in bed you should consider buying a high quality down comforter from a down bedding specialist, otherwise you will be replacing your down comforter every 3 or 4 years, and you will not be able to use it year-round. Choose a high quality goose down comforter from a down specialist and you will enjoy it year-round for many years, plus if they offer cleaning and renovation services, you will have it for life.
Here is what you really need to know:
1) All down is not created equal. Goose down is better than duck down. Down from mature geese that live in cold climates produce larger down clusters that trap more body heat keeping you warmer as well as lofting up to produce a comforter that is puffy without weight. Fill-power is the measurement of a down cluster's ability to loft up after compression. 650 fill-power and up is considered luxury quality. The higher the fill-power the greater the thermal properties and the puffier the comforter. There is also cluster count to consider. This is the percentage of whole down clusters as opposed to pieces of broken down known as "fly". Canadian White Goose Down is considered to be the finest white goose down in the world. Siberian, Hungarian and Polish white goose downs are premium qualities and the very rare Eiderdown, the ultimate in softness and warmth without weight is the best down in the world.
2) Down will eventually "leak" out of anything other than a cotton cambric down-proof fabric. What makes the long staple Egyptian cotton fabric down-proof is not just a high thread count but calendering. This is a natural process of compressing the fabric between giant steel rollers to fill in spaces invisible to the eye. The best cambric cotton down-proof fabric comes from Germany or Switzerland. Many of the cambric cottons are made with a sateen finish. They are very soft, durable and breathable. Thread counts over 300 are best and will remain down-proof for 10-15 years. For Eiderdown the best ticking is Swiss Batiste the lightest of all down-proof cambric cottons with the highest thread count, sateen finish and a silky soft touch, woven specifically for Eiderdown the softest down in the world.
3) Comforters come in open stitch (Karo-Step and Ring Stitch) where the filling can move, closed stitch (sew-thru box stitches) fixing the filling into one small box, Baffle Box Stitch, which is a modified box (the filling will move, though less than in a ring or Karo stitch), and the Baffle Channel Tri-Wall construction, a channel stitch with a triangular baffle wall to prevent unwanted shifting. The channel tri-wall, the ultimate couple friendly comforter style, is very beneficial as it allows the filling to be adjusted on one side for truly individual comfort. This is especially useful in summer, or when one person is a warmer sleeper than the other. Baffles prevent cold spots and allow premium downs to loft up to their full potential. Less filling is required in a sew-thru stitch, making these comforters better for summer.
4)The temperature of your bedroom will determine the best comforter for you. Look for a year-round goose down or Eiderdown comforter. Most high quality goose down or Eiderdown comforters are year-round for bedrooms 60 - 72 degrees.
