compression mat for dry mount press

The thermostat on my Seal 160m dry mount press died on me so I managed to burn the devil out of the foam mat inside it. It go so blessed hot it burned it through 2 sheets of matte board and a fiber print. Anyone know where I can buy a new mat? The thermostat is easy, but can't find a vendor for the mat. Any suggestions will be greatly appreciated. Don

These are routinely available from picture frame supply wholesalers, who cater to that specific trade. But I simply bought my last one from
B&H.

B&H lists mats & thermostats. I ordered a mat from them, no problem a year ago.

I got one at B&H for my Seal 200. (there was a url link here which no longer exists)
