Golden M

rational is one of the first kitchen manufacturers to have been awarded the "Golden M", quite possibly Europe's most important quality mark. The Deutsche Gütegemeinschaft Möbel e.V.“ (German Quality Assurance Association) only awards the "Golden M" to furniture which has passed extensive and stringent testing. The furniture must be sturdy, safe, durable and well made and may not contain any substances that could pose a health threat. This gives the kitchen consumer the assurance that the furniture being purchased is of the best possible quality and has been reliably tested and approved as being non-harmful to health.

Tested safety

The Institute for Product Testing and Quality Control, the LGA Bavaria/Germany, has conducted tests on all the rational furniture ranges and certified that in terms of construction and technical equipment all the safety requirements have been met. In recognition of this, rational has been awarded the GS safety mark.
