I haven't read every single reply so I am sorry if this is a repeat.
When I was at the end of my pregnancy with both children I slipped one of those crib flat waterproof thick sheet things under the sheet on my side of the bed in case my water broke while sleeping (I got lucky and it happened in my garage, but I digress!). I have NEVER been so hot sleeping in my entire life. There must be something about the material and its absorbency that traps heat. If you are looking to warm up a bed without using an electric blanket or buying new sheets, try putting those water proof pads in under the fitted sheet.
