Great from 35-45 temp comfort zone ... is it true?

Not really, the insulation is spotty and doesn't maintain heat well in too cold of temperatures.

I live in Southern California where it rarely gets below 35° so I can't say for sure. We have frost at my house on a lot of winter days and it has held up fine.

We love ours. It heats the area well. We keep it between 1&2 most of the time keeping our heat at about 70 degrees. We love in northern Maine where temps have been -20 and up to -40 on a pretty regular basis and it has been extremely reliable. I haven't let the temperature get down to 45 to test that theory.

I'm very hot-natured and hate being hot. We sleep in tshirt PJs with a sheet and a cotton blanket at about 74-75F thermostat setting at night in the summer (78F on thermostat during the day to factor any residual warmth in the mattress), and my back does get warm, but not sweaty. In winter, though, we save $$$ by not needing to run the heater much, if at all, at night (about 68-65F in the house).We're happy enough with the 12 inch mattress and use the warmth to our advantage in winter. We decided on the 12 inch because we measured how far down we sank on our old memory foam mattress. It was a good 8 inches. That fact trumped our questions about heat. hehehe I'm very hot-natured and hate being hot.

I believe I read 500 degrees. Maybe it was 450 - I just remember thinking it was above and beyond what I would ever require. Hope that helps!

Totally agree with other answers and also love the temperature setting; highly recommend!

I use it below 40 with no problems. It generally only heats up to 102 when it's really cold. It cools pretty quickly if you use the jets. It's pretty awesome in general.

There is a heat adjustment fron 350 to 450!! Give it a try, you wont regret it

No. The temperature settings are in celsius,50-75 Celsius. Anything below 50 is in the "cool zone." but the numbers are the best way to set your temp.

We live in Denver and turn our thermostat down to 62 degrees at night. This was WAY too warm for that, so we tried 59 degrees. That was better, but still too warm. I wish this comforter came in a light warmth - it's a really, really nice one, just too warm for us.

I have mine connected to turn on below 35 degrees, and it works well for me.

I live in Southern Californina so 35 degrees is horribly cold here, that said I only use the 2 or three setting and it is perfectly. I use the 6 setting for 10 minutes before I turn in, I couldn't take the 6 setting all night...too hot. By having this I do not have to turn the furnace on all night which saves about 1.50 per day. (Remember this is Cali and it is never too cold.) If you really want to toast and still save money get an electric blanket on top and the mattress pad below. You could run both for 25% cost of heating the whole house with a furnace and you can be like the cheese in a cheese sandwich.

We have been out around ours at 50 degrees and were very comfortable. Not sure if you can be out in much colder weather. The fire is not that large so the heat does not radiate very far. It is more for the look than the warmth I believe.

I had mine to 700 degrees F and turned it down as it was much too hot for my purposes.mdont know if it could have gone higher.

You will survive at the listed rating, but your comfort will be in question. I was ever so slightly chilled wearing thermal underwear in a 27 degree night on a wooden platform in an Adirondack cabin. Using additional insulation below and above you might help make it work below 5 degrees, but we are planning to get different bags for camping in those conditions.

I have 2 of these and love them, however at 30F it is not as warm as we would like. Had a scout camp over weekend and both me and my son were quite cold with outside temp around 30 even though we had thermals + pants with wool socks (feet were esp cold). Bag is great above 35 or 40, but need a top cover or thicker bag for freezing weather.

We got to +15 here once and thought we were going to freeze to death! Anyway, I have not tried them that cold, I suspect they'll work just fine since most electronic things like that are good down to -40. We used to live in Edmonton, AB, it hit -47 (without windchill) once, we decided to move.
