The materials in the house where chosen with a strong regard of their impact to the environment. You are surrounded by a lot of oiled wood which is a most sustainable building material. Please be informed that it may not be cleaned with usual cleaning materials but best with a damp cloth. We recommend always to use placemats and coasters in order to not get spots on the tables. Should you prefer to use a Table cloth, you will find one in the kitchen. Especially with smaller children that might be less stressful.
