Doubling sheets or an extra blanket on top of sheets is a good way to provide extra warmth. Mattresses tend to let in cold air.

I just found out that if you put a blanket under your waterbed mattress and up the sides that you can save up to $18 per year PER bed!! In January we are draining all 4 beds and doing this so we can see the difference at the end of the year. I would imagine that the heat would escape through the box springs as well so I can see why this would make sense on a regular bed.

Wow, I didn't know that! Jack is always cold anymore and I am always hot now! My how things change? :laugh:

I'll try this when I change the sheets tomorrow. :)

I had never heard of this either. I will be giving it a try......:)
