Three things to consider when investing in a down comforter: fill power, baffle box construction and a cover with at least a 200 thread count. The higher the fill power, the fluffier and warmer the down. Baffle box construction keeps down feathers at their highest possible loft and gives the down an even distribution throughout. High thread count, down-proof covers keep down from escaping and feel soft against your skin. Down alternative comforters use certain types of polyfill that feels like feathers and insulates like down. The down alternative comforters are perfects for guest rooms as well as for households with fowl allergies. Even though down is most always washed and disinfected, down alternatives ensure that allergies to feathers never occur. Comforters from Blue Ridge Home Fashions, DownTown and Melange Home are great brands to start looking for your new bedding.
