does the heat extend to the back part or just the chest part

The Heat begins and radiates from the center of shoulder pad. So, it's warm around the chest. I returned mine, it was heavy, my father is 77. Would work great on a big guy.

Yes! It has lower back, upper back, and full back buttons! With or with out heat! Sometimes I stack a few pillows, and sit on them to get really low on the back! In turn, sometimes I slouch down on it to get my upper back, neck, and head!

I have heated seats only and I can feel the heat as the cushion warms up, so I assume the same with cooling. I love this seat cushion not only for my back but I also sit higher which I like.

Having only used only black I can't answer this question completely. The helmet is vented extremely well. My grandson never complains about the heat and I am told that it is cooler by far than their bicycle elements. Hope this helps.

I cant really say for sure about FL heat because im in PA, but i felt it was significantly cooler than the Baby Bjorn I used when my son was first born. That thing was swampy after awhile! :)

Yes. I would not hold my hand in front of the parts that heat up for an extended time, just because I always feel it's better to err on the side of caution, but the entire body of the heater is cool to the touch. The hot parts are well-recessed behind deep fins on the front of the unit.

If I remember right I have read that at least 5" on back, sides and top. I have not notice any heat or vents on the outside of mine.

Simple, it isn't. Rather, the chest temp. is a balance between the outside temp., the efficiency of the insulation and the efficiency of the cooling mechanism, which runs at full capacity all of the time. For most of us with a/c in our vehicles, that yields a satisfactory chest temp.

no just the one side. However you can feel the heat from the front. But it only heats up in front. thanks.

I would say no. The heat in it is wonderfully subtle. I suppose you could make it hot enough to act like a pad for back pain, but the entire pad, or your side of it anyway, would all be just as hot.

I couldn't feel heat either but cat loves it. It is on top of a low chest and has become her favorite place ...spends hours there.

Lower Center of the back, as are most heated car seats. It's great for the lumbar area and the heat combined with the vibrating massage is perfect for those long trips.

It is cold all around arm and then shoulder area - doesn't feel that cold under armpit. So yes to the beginning of armpit

I emailed the company that makes this product. The customer service guy was very helpful. His response to that question was that there is no radiation threat since the chest area has more tissue, bone, and cartillage, and the brain is not getting the radiation; he said doctors had said that. He did not say anything about that little heart shaped piece being shielded. Being a female, I would prefer not to wear something so close to my chest. Perhaps, throw the whole thing over my back???

I think all memory foam holds your body heat to some extent. I sewed some pillow cases for mine so with the extra layer between me and the pillow I haven't noticed it being hot. Although it has been fairly cold here yet, so I guess we'll find out soon enough!

Mainly the back. One of the better feeling cases though, just wish it had a spot for the dimple on the back.
