driving is about the only time we're both together it has a warm to a hot feature warm is perfect it makes it feel like how your bed feels once you warm it up it just stays that way the cold if it's on cold 10 when you get into cold sheets like it's freezing outside and you getting your beds freezing to me it stays filling that way everywhere that it's touching your body and so if you're laying on your side you're not getting near as much cold as if you're laying flat on your back
