Environmentally conscious cushions, that's what we stand for. Munich has a simple goal, to warm the buttocks. The rechargeable battery has an effective sitting time of 3 hours. This has been thought through: the Sit & Heat cushion only heats up when someone sits down on it. As soon as the seat is vacated, the heating switches off automatically after two minutes. Battery empty? Then the battery is easy to charge, change and connect.
