Our commitment pays off

We have been audited and certified by external institutions.

Produktion quaility control

The demands and expectations are continuously being redefined. This calls for highly qualified staff who practice perfection from incoming inspection to nishing. Crucial here is our quality management that monitors and steers every step of the manufacturing process with the necessary sensitivity. Ongoing audits and tests in the testing laboratory in line with RAL GZ 436,  RAL GZ430 ­, ISO and GS, tested safety, accompany the entire production chain. Here, not a single detail escapes the trained eye of our engineers when it comes to ensuring constant quality.


Möbel Made in Germany

Made in Germany Label

The “Möbel Made in Germany” (“Furniture Made in Germany”) label guarantees that our products are demonstrably produced in Germany. Accredited by the German Institute for Quality Assurance and Certification (RAL), this guarantee of origin is a mark of reliability, safety and healthy living. The demanding criteria ensure that in addition to a high level of production, process steps such as design, quality assurance and assembly also occur in Germany. The requirements are monitored by the Deutsche Gütegemeinschaft Möbel (DGM).


Circular sustainable furniture

Circular sustainable furniture

Schüller Möbelwerk KG was audited and certified for the first time on 08/09 July 2024 for the new RAL quality mark RAL-GZ 436 ‘Furniture - circular sustainable’.

The new RAL quality mark brings together all previous DGM requirements for the sustainability of furniture, supplements them, particularly in the area of verification obligations for certified manufacturers, and thus creates a holistically reliable orientation aid for sustainable furniture purchases.



Carbon-neutral company

The basis for a climate neutral furniture manufacturer is the carbon footprint. To receive certification as a climate-neutral furniture manufacturer, the manufacturer is required to calculate its "footprint" every year on the basis of 3 scopes. This footprint is made up of direct and indirect greenhouse gas emissions. The calculated carbon footprint is compensated for by purchasing (redeeming) high-quality international climate protection certificates that meet the Gold Standard, the VCS Standard or the Clean Development Mechanism. As Schüller has eliminated all CO2 emissions of the 3 scopes, the company has been awarded the highest level of "Climate Neutral Furniture Manufacturer". 

PEFC label


In 2010, the company decided to undergo certification to the PEFC standard. PEFC is an acronym for "Programme for the Endorsement of Forest Certification Schemes". The displayed PEFC label is traceable confirmation that the woods and wooden materials used originate from ecologically, economically and socially sustainably managed forests and controlled sources. The obligation to regularly provide proof continuously ensures adherence to the PEFC Chain of Custody.

Goldenes M / Emissions label class A


The Deutsche Gütegemeinschaft Möbel e.V. (DGM) only awards the “Goldenes M” (“Golden M”) to furniture that has been put to the acid test. It must be stable, durable and offer good workmanship. The emissions label class A confirms that the products do not emit any pollutants that pose a risk to health. Rigorous testing and continuous monitoring ensure that furniture with the RAL quality label offers consumers high quality standards and surpasses legal requirements with regard to protecting health and the environment.

GS certificates

GS mark

By awarding them the “Geprüfte Sicherheit” (“Certified Safety”) seal, TÜV Rheinland LGA Products GmbH has confirmed that the kitchen units in our current collection meet all legal requirements with regard to user comfort, durability, material consistency and safety.

Energie management system certificates

ISO 9001 /
ISO 50001

The quality management system DIN EN ISO 9001:2015 introduced voluntarily in the company regulates the customer orientation and process quality via defined procedures. From product development through production and installation to customer service.

The energy management system introduced under DIN EN ISO 50001:2018 requires companies to reduce their energy consumption in a structured and systematic manner by continuously recording and evaluating energy data as well as by taking subsequent measures to improve their energy efficiency.
