The three warmth weights
Every one of our down comforter lines is made in the same three warmth weights. The shell, the fill and the construction are identical, only the ounces of down inside change.
Match the weight to the room, not the season
A comforter lives in one room. A Winter Weight in a bedroom held at 68 degrees will spend the summer folded at the foot of the bed, and an All Year Weight in a room that sits near 60 all winter will get pulled off by 3 a.m.
Ask what the room actually is: how warm the thermostat holds it, whether a window stays cracked, whether it sits over an unheated space. That answer picks the weight more reliably than the month.
- Thermostat near 65 to 70 year round: All Year Weight
- Warm room or a hot sleeper: Summer Weight
- Cold room, open window, or a permanently cold sleeper: Winter Weight
What the ounces actually look like
The warmth weights differ by fill weight, and fill weight scales with the size of the comforter. A queen-size BERNINA 650 carries roughly 24 ounces of down in Summer Weight, 34 ounces All Year and 46 ounces in Winter, the same shell, three very different beds.
Fill power changes how those ounces feel. The same All Year warmth in a 920 fill power line arrives in noticeably less fill than in a 560, which is why our highest fill power comforters are also our lightest.
Two sleepers, one comforter
When one of you runs hot and the other is always cold, an All Year Weight is the usual compromise. Many couples find the better answer is to size up one step, the extra drape lets the warmer sleeper keep a foot out without stealing the whole comforter.
If the gap is genuinely large, tell us. We will walk through the room, the thermostat and each sleeper's habits before naming a weight, which is faster and more honest than any chart.
If you sleep hot
Sleeping hot is usually a room and layering problem, not a comforter problem, but the comforter can stop fighting you. Choose Summer Weight, keep the shell cotton rather than synthetic where you can, and add a blanket you can throw off at 2 a.m. instead of buying warmth you will push away.
A down alternative comforter is a reasonable second piece for hot nights and for guest rooms: it breathes, drapes like down, and washes at home without ceremony.
