Seat has round HARD things covering the part you sit on VERY UNcomfortable AND the heat doesn't come out of the bottom part of the seat as it says on the box on EITHER of the 2 units I purchased.
The cooling, heat from the lumbar part & lumbar support area all fine -
FIX the heat to come out of the seat part as they say it does --- CUSHION the seat --- QUITE the massage noise & this would be an AWESOME, FABULOUS product
