Quality starts with the details

MEASURE, UNDERSTAND,

OUR TESTING PROCEDURES

At REINHOLD KELLER, quality is not a matter of chance. In our quality assurance, we rely on structured processes and a modernly equipped testing center to specifically examine furniture components. The focus is on the question: Does the product meet the defined requirements – and if not, where is action needed?

Our tests particularly support the development process and hell to reveal potential weak points – providing a solid basis for wellinformed decisions, whether as part of random sampling or for targeted optimization.

With state-of-the-art testing tools, clearly defined processes, and an experienced team, we ensure transparency – creating the foundation for a well-founded quality assessment in-house.

Measuring Arm – Precision down to the smallest detail

In quality assurance, every Millimeter counts – especially for precisely Fitting furniture components or custom-made solutions.

The 7-axis measuring arm uses laser technology to detect even the smallest surface details. The generated model appears directly on screen and is ompared with the CAD data, making deviations immediately visible – even in hard-to-reach areas. All data flows directly into our QA documentation.

These insights help us optimize the assembly of individual components, such as seat shells and frames. We also use the tactile probe to capture measurement points for new constructions – for example, in reverse engineering.

Test bench – Long-term stress? We're testing it!

To realistically assess how our furniture performs under everyday conditions, we put it to the Test on our load testing bench. The goal: to determine how the furniture behaves under repeated use.

We simulate real-life scenarios such as sitting down, leaning back, or supporting oneself on furniture edges. Repeated Forces are applied to specific zones – including asymmetrical pressure points.

We observe how joints, material stability and structural integrity Change over time – and document all results in detail.

In high-traffic areas such as restaurants or lounge zones, furniture is in constant use. Our test bench helps us identify at an early stage whether a product can withstand this level of stress over the long term.

TIP-AND-FALL TEST – STABILITY THAT LASTS

In the object area, chairs are often subjected to changing loads – such as tilting movements, shifts in weight, or leaning back.

During the tip-and-fall test, a chair is repeatedly subjected to controlled tilting and falling movements. We specifically test the stability of the construction, the strength of the connections, as well as the behavior of the materials under dynamic loads. The goal is to reveal potential weaknesses in the overall construction.

Whether in a hotel room or a Fitness studio – if guests lean back on a chair or tilt sideways, the furniture must not give way. The tilt-fall test gives us a reliable basis for assessing stability under realistic and comparable conditions.

MARTINDALE-TEST – RESILIENCE PUT TO THE TEST

In everyday life, materials and surfaces are subjected to mechanical stresses due to movement, friction, and constant use. To evaluate the durability of such materials, we conduct Martindale tests.

In this process, the material is subjected to uniform rubbing motions under constant pressure over a defined period. During the test, it is observed when the first visible signs of wear appear. This helps assess how long a fabric or synthetic leather remains durable in use before typical damage patterns develop.

In high-traffic areas like restaurants or hotels, fabric covers are exposed to daily stresses. The Martindale test helps us better assess the suitability of a material for such applications.

Measurement Board – Custom precision, made measurable

For reliable quality control, reproducible measurements are needed – especially for recurring components with complex geometries.

The measuring board consists of a 3-axis measuring table with a turret head. The turret head allows for quick switching between fixed probe tips for various contours – for example, to check component dimensions, drill holes, or milled features.

The measurement results are directly transferred to the system and documented – this saves time and ensures consistency in the inspection process.

Especially in batch production or machine setups, the measuring board helps us reliably check if components have been manufactured correctly before they move on to the next production stage.
