The Queen Biomat is the size that I use. I like being able to have one side on the highest setting and when I want to cool off and go on the low setting I can move over to the other side of the mat. I use my chi machine on the far low setting side so its always there for me once I break my first sweat. This is also the one to get if you and your partner have been fighting over the one professional size Biomat. At night, this puts me to sleep faster than anything. It's like being warm and rocked like a baby.
The Queen Biomat has more convection than the model with the fabric covering. The temperature when I used my laser thermometer on the surface was much hotter than the Professional size that had the built in cloth covering on top. Many people use the cloth sheet on top on top of the built in fabric on the Professional model. The queen will have one less cloth if using the white cloth that comes with it.
The Queen is the mat that many people upgrade to once they get their professional size. I often have demo professional size models from those who have upgraded to the queen size. If you want to feel what it is like to sleep on a Biomat but don't want to invest in a larger size just yet, ask me about my loaner Professional size models. They all come with a waterproof pad.
