Product information

Sit & Heat heat cushion Oslo
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.

The pouch behind the seat contains the rechargeable battery. A nice spot for a logo!

Due to the smart sensor, the heated cushion only turns on when you sit down.

Using the front or side controls, you can determine the heat yourself.

Hand washing

Soak the fabric in a solution of 60ml of mild soap per 3.8 litres of lukewarm water. Use a sponge or very soft brush to gently brush away the stain. Rinse thoroughly to remove all soap residues. Allow the fabric to air dry.

Washing machine

First close all the zips. Then wash the fabric in the washing machine with cold water on the gentle wash programme, using a standard amount of mild detergent. For stubborn mould add 235ml of bleach. Let the fabric air dry completely.
