The pouf from the series Stilla has a covering in velvet. It is recommended to vacuum the pouf often when pouf can linting in the beginning. Remove all stains immediately, first only with a dry white cotton cloth, and then you can spray lightly with water and dab with a clean cloth. If the stains do not go away you should you not use chemicals. The color of the pouf can be bleached if it is in direct sunlight for a long time. We also recommend that you have a base mat under the pouf on vinyl flooring, oiled or untreated floors when stains from the underside of the pouf can occur.
