See the Stability 4: Vernal Core3 Full-Load Lifting Endurance Test

When we describe a standing desk as "stable and durable", "quiet in motion", or "safe and reliable", these words sound appealing, but how do they actually perform in real use?

In February 2026, alongside the launch of the Vernal Core3 standing desk, Vernal released the Core3 Test Report, publicly sharing data and details from real laboratory testing. Through this report, Vernal aims to give users a clear understanding of what kind of desk they are truly bringing into their workspace.

You deserve to know the real quality of the desk you take home.

In this article, we highlight the 2.1 Full-Load Lifting Endurance Test from the Vernal Core3 Test Report, taking you inside Vernal’s testing laboratory to show how a series of rigorous tests are used to verify every detail of the desk’s stability.

Overview

To verify reliability and stability under conditions of long-term frequent use and high loads, continuous cyclic validation was conducted on the lifting system, mechanical structure, and control system under rated load conditions. The test simulated real-world scenarios, including high-frequency daily adjustments and full-load operations, by executing repeated complete lifting strokes. A duty cycle with cooling intervals was incorporated to approximate actual operating conditions. Throughout the testing process, lifting noise, load capacity, self-locking performance, and operational smoothness were monitored, with specific focus on evaluating structural fatigue, control system endurance, and control precision degradation.

Test Objective

To verify the stability of the standing desk's mechanical structure and control system under conditions of long-term, frequent operation. This test ensures the product maintains smooth lifting performance, resists mechanical failure or performance degradation, and guarantees reliability over an extended service life.

Test Method

• One lifting cycle was defined as a complete ascent and descent based on the full lifting stroke.
• The test was conducted using a 10% duty cycle mechanism (2 minutes of continuous operation followed by 18 minutes of rest).
• Testing was continued until the occurrence of functional anomalies, abnormal noise, or structural irregularities.

Assessment Criteria

Throughout the testing process, the following performance standards were enforced for each cycle:

• Operational noise levels must not exceed 50 dB.
• The system must maintain the ability to lift a load of 160 kg (353 lbs) during ordinary operations.
• The static self-locking capacity must be no less than 240 kg (529 lbs).
• The static self-locking capacity must be no less than 240 kg (529 lbs).

Test Results

• 160 kg (353 lbs) Load: 14,000 cycles completed without anomaly.
• 0 kg (0 lbs) Load: 17,000 cycles completed without anomaly.

*This anomaly is verified strictly in accordance with the assessment criteria specified in Test 2.1.1.

*Laboratory Lifting Endurance Record

As of the report release date (Feburary 9, 2026), four Core3 standing desks remain under active testing at the Vernal laboratory. The unit with the longest testing duration has accumulated 30,000 lifting cycles. The lifting function remains normal, and no reduction in lifting speed has been observed.
