I tried again with a 1 foot diameter x 1 inch expanded polystrene foam circle.

Results: From 28c to 90c took 9:14
Time saved compared to no insulation (14:09): 4 minutes, 55 seconds
Time saved compared to 7x7 inch pot holder on the bed (10:20): 1 minute, 6 seconds
Removing the foam caused a drop of 2c for about 1 minute.
Note: melting temperature of polystrene is supposedly around 100c

Cool! -- er, hot! (-:
The logical next step is to insulate the bottom of the bed. If you find something safer and thinner than polystyrene, you can make it permanent.

For that I was considering a silicone baking mat trimmed to fit.

For those interested, I'm heating my bed to 125C. Once the bed reaches temp, I remove the towel and typically see a drop of 1c for approximately 2-3 minutes. Considering I get decent adhesion at 115c I'm well within what I deem acceptable range.
