Luxurious Sensorpedic Mattress Toppers

Which of the two are better? What is the difference between them? What is the foam lb density of both, are they both memory foam and do they both have cooling gel in them? What are the overall differences, what are the levels of support firm,med, soft,plush? Thanks

Hello, I work for the manufacturer. Both toppers have the same density, the 3 inch Regal has a gel-infused top and the other does not. They are both memory foam and both have quilted tops but the Regal is a little more firm.

And that density would be?
