The coolcat works well on our unit with the King bed layout ,of coure there are no controls on the unit, all controls are on the thermostat. My one inconvenience is the person sleeping on the backside gets no fresh air at all when not using air conditioning. The dw gets all grumpy when you get up and have to crawl across to get out of bed through the narrow opening as well. I guess everything is a compromise.
