Mattress Warmers

There are few things as luxurious as getting info a pre-warmed bed on a cold
night. If nothing else, it makes it easier to get to sleep, because you don't
spend the first twenty minutes hunched up and shivering.

If you have a memory foam mattress topper, there's another advantage. Memory
foam is very temperature-sensitive, so in cold weather it's uncomfortably stiff
until your body warms it up. With a 12V mattress warmer, that won't happen.

My 12V mattress warmer draws 6 amps, and I run it for half an hour before
getting into bed, then shut it off--from then on I keep the bed warm by
myself--so it only uses about 3 amp-hours per day, which is insignificant. It's
one of my favorite enhancements to my rig.
