Timber materials/Hardware/Tolerances

Particle board/MDF (medium density fibreboard):

Timber materials are mainly made of wood. They include, for example, medium density fibreboard or particle board. The quality of a product does not depend on whether the furniture is made of timber materials or solid wood. The fundamental criterion is the quality of the materials used. We manufacture our own particle board to a high level of quality. In particular, the components are tested to strict EC guidelines by impartial accredited institutes, e.g. Fraunhofer Institute or IHD, to make sure that they are not hazardous to health. Moreover, timber materials sustainably protect our resources.


Solid wood/Veneer:

The individual growth characteristics make each solid or real wood piece of furniture unique. But solid wood/veneer are also demanding. They require a consistent room climate and a relative humidity of 45-55%. Even so, there is no way to prevent solid wood from warping, swelling, shrinking or developing minor cracks. Smaller deviations do not impact the use, benefit, function or useful life. The solid wood/veneers we use come from controlled forestry operations in the EU and North America.



You should regularly check and adjust the furniture hardware to ensure its functional reliability and to avoid consequential damages. This applies even more if the condition of the hardware has changed since assembly. You have a duty of care, by law. Please only use original spare parts if you need to replace parts of the hardware.

Graphite powder, for example, can be used to loosen stiff metal locks (can be obtained in car accessory shops).

If door hinges squeak, the joints and pivots can be treated with silicone spray or resin-free sewing machine oil.Metal or plastic drawer rails should be cleaned once a year using a dry dusting brush. Unlike plastic runners, which can be treated with a little paraffin, the rollers/balls on metal rails must not, under any circumstances, be lubricated.

The hanging and sliding rails on sliding, suspended or folding doors require virtually no maintenance. They should occasionally be wiped with a dry cloth.



Furniture manufactured in industrial environments is subject to certain tolerances as a result of the processes and materials used in its production. Dimensional tolerances or slight deviations/offsets, e.g. colour, structure of designs, adjustable parts, applications on drawers, shape and colour of glass tops, etc., which remain within the scope of nationally and internationally applicable standards, do not constitute material defects. Instead, they are deemed to be "typical characteristics of the merchandise" (Source: RAL GZ 430). They are "acceptable deviations caused by production and manufacturing processes" that do not impact the use, function, utilisation, safety and useful life.
