The wallpaper is protected with multiple layers of high-quality varnish, which gives it a durable finish. The painted parts are also protected with varnish. So you can clean it with a slightly damp cloth. Preferably no cleaning agent, that is often too aggressive.
Do not use abrasive, acidic, solvent-based or greasy cleaning agents.

Scratching objects such as ceramics are best provided with a layer of felt or a coaster. Ceramics quickly get scratches when you move them.

Never place your furniture in direct sunlight. Wood is very sensitive to discolouration.

Do not place your furniture near a heat source such as a stove or radiator.
