What are the advantages of down and down-alternative comforters?

Down is light and naturally insulating but can adversely affect allergy sufferers. If you suffer from allergies, a synthetic comforter is better. Often these have more filling to retain heat and can feel warmer than down.

What weight should I consider?

For hot summer nights or warm climates, you'll only need a super lightweight comforter. For year-round use, a medium weight is ideal while an extra-warm weight is better for early spring or late fall. The warmest comforter has an ultra-warm weight to give you a cozy night's sleep in the middle of winter.

What does "fill power" mean?

This is the volume of down or down-alternative per ounce. The higher the fill power, the better insulation your comforter provides. So for a colder room, opt for a higher fill power.
