Wood materials / fittings / tolerances / load capacity


Particleboard / MDF (medium density fibreboard):

Wood-based materials are mainly made from wood. This also includes medium density fibreboard or chipboard, for example. The quality of a product does not depend on whether the furniture is made of wood-based materials or solid wood, but on the quality of the material used. Our chipboard produced in-house is of high quality. In particular, the ingredients are tested for health safety by independent, accredited institutes such as the Fraunhofer Institute or the IHD in accordance with strict EC directives. In addition, wood-based materials sustainably conserve our resources.

Solid wood/veneer:

Different natural growth characteristics make every piece of solid wood or real wood furniture unique. However, solid wood/veneer is also demanding. They require a constant room climate with a relative humidity of 45-55%. Nevertheless, warping, swelling, shrinkage or minimal cracking cannot be avoided with solid wood. Minor deviations have no influence on use, benefit, function or service life. The solid wood/veneers used come from controlled forestry in the EU and North America.


To ensure the long-term functional reliability of the furniture fittings and to avoid consequential damage, you should check the furniture fittings regularly and readjust them if necessary. This applies all the more if the fittings should ever deviate from the condition in which they were installed and is part of your duty of care according to the law. If replacement parts are necessary, please be sure to use original fittings again.

Furniture locks that are difficult to operate can be made operable again with graphite powder, for example (available from car accessory dealers).

If door hinges make noise when moving, treat the joints and pivot points with silicone spray or resin-free sewing machine oil. Drawer runners made of metal or plastic should be cleaned once a year with a dry dust brush. In contrast to plastic runners, which can be reworked with a little paraffin, the rollers/ball bearings of metal runners must never be lubricated.

The hanging and sliding rails on sliding, sliding and folding door fittings are largely maintenance-free. They should be cleaned occasionally with a dry cloth.


Industrially manufactured furniture exhibits certain tolerances due to both processing and material. Dimensional tolerances or slight deviations/offsets, e.g. in designs, colours, structures, drawers, adjustable parts, applications, glass overlays, format and colour, etc., which are within the national and internationally applicable standards, therefore do not constitute material defects.

Rather, these are "typical product characteristics" (source: RAL GZ 430), which are "acceptable production and manufacturing deviations" that have no influence on use, function, utilisation, safety and service life.

Load table:

The maximum permissible load on our shelves, drawers, clothes rails etc. depends on the respective material properties (wood/metal etc.). We provide you with aload table for downloadwhere you can see the respective maximum permissible load.
