It's true that the seats aren't air conditioned in a sense that the air is not coming from the compressor, condenser and blower unit... BUT it is NOT just circulated ambient temperature air either. The seat back and seat cushion actually contain a thermal electric device.

From the repair manual:

SEAT CUSHION AND SEATBACK TEMPERATURE ADJUSTMENT FUNCTION
• One thermal electric device (TED) unit is installed in each seat cushion and seatback. The device heats or cools, sends airflow to the seat surface, and adjusts the seat temperature.
• The thermal electric device (TED) is a heat exchanger that has a function to heat or cool the airflow from the seat cushion blower motor and seatback blower motor. (By changing the direction of the current from the
power supply, the device takes or gives heat, and adjusts exchange process depending on voltage.

I stand corrected. However, the heater function works far better than the cooling function which feels like ambient air. But that's just my opinion. Does anyone actually get a really good cooled air flow? I don't.

I've actually turned mine down as it was too cold.

I really appreciate all of your responds... The reason I was wanting some cloth feedback is because every car I have owned in the last 15 years has had leather and even though they are not verts they are hot as hell in the summer and make me sweat pretty bad.

One of the vehicles that I own now (1970 Bronco) has no top and has synthetic leather waterproof seats that you could not pay me to sit on if the bikini top was off.

My idea was if I parked this future purchase roadster with the top down I can jump in without burning my a$$!

Your thoughts...

Your interior and seats will be hot sitting in full sun with the top down. The mesh in the middle of the leather sides on the roadster with the cooled seats does help though.

Mine is indeed cooler than ambient air temp, i'm not sure by how much. I'll measure the seat temp with my non-contact infrared laser thermometer tonight.

Just FYI, I have a little thermoelectric cooler I use for drinks on long trips. It keeps my drinks about 40 degrees cooler than the ambient air temp. It's not ice cold by any means but i don't have to worry about using ice or loosing volume inside due to the ice.

I've found that putting my cabin A/C on "face and feet" so that it directs some air into the footwell greatly improves the feel of the seat cooler performance.
