A classic patio chair with a modern twist, meet our Oslo. Created to allow chairs with a rounded top to become one with the cushions of Sit & Heat. This comfortable cushion keeps your whole body warm, thanks to its heated back and seat. The rechargeable battery has an effective sitting time of 3 hours. It has been well thought out: 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.
