Step 2:  Check Adjustment Speed and Noise Levels.

Dual motor systems are designed to offer faster and quieter height adjustments compared to single motor frames.

Tips:

• Look for an adjustment speed of at least 38-50mm/s(1.5–2 inches) per second for efficient transitions.
• Ensure the noise level is below 45 dB to avoid distractions in quiet environments.

Testing:

• Operate the desk during testing to evaluate speed and noise levels under various loads.

Step 3:  Prioritize Stability.

Stability is crucial for standing desks, especially at taller heights. The stability of a standing desk depends on several factors: the design of the sliding system; the overlap between lifting columns, where has more overlap can reduce wobbling; the frame structure design, which provides balanced support; and the overall product weight, as heavier frames offer better stability by minimizing vibrations during use.

Tips:

• Ask specifications on sliding system.

Materials: Inquire about the material used for sliding pads (e.g., nylon, PTFE). Durable materials reduce wear and ensure smoother movement.

Thickness: Request data on the thickness of the sliding pads and how they are tested for longevity.

Testing Procedures: Ask if the manufacturer conducts friction and durability tests on the pads under load.

Design: Ask use which design on sliding system – long design or short design? Long design provided more support, which more stable.

Key Question: What material are the sliding system made of, and how do you ensure they maintain stability over time?

• Request specifications on Column Overlap.

Ask for Measurements: Request the specific overlap dimensions between the inner and outer lifting columns at minimum, mid, and maximum heights.

Industry Standards: High-quality frames typically maintain a column overlap of at least 25–35% of the column’s length, even at maximum height.

Precision Engineering: Discuss the manufacturer’s techniques for ensuring consistent overlap during production, such as advanced machining and quality checks.

Alignment Control: Ask how the manufacturer prevents misalignment during the assembly process to maintain proper overlap proportions.

Wobble Tests: Inquire if the manufacturer conducts stability tests to simulate real-world scenarios, especially at maximum height with minimum overlap.

• Check the design on frame structure.

1. Base and Leg Design: Frames with a wider base provide better support and balance, reducing the risk of wobbling or tipping, especially at maximum height.

Base should designed in a T-shaped structure, which enhances load distribution and overall stability. A key factor in stability is the size of the lifting column tubes. Larger column tubes provide a greater surface area for contact between the sections, reducing wobbling and lateral movement, especially at maximum height. For example: Frames with lifting column dimensions larger than standard (e.g., 70x70mm or greater) offer better stability compared to smaller columns.

Thicker Tubing: In addition to size, thicker tubing walls further improve structural integrity and resistance to bending under heavy loads.

2. Lifting Column and Expand Beam Installation for Stability.

The best is three-sided installation, where the expand beam connects to the front, back, and sides of the lifting column—is considered the most stable configuration. By securing the lifting column from three directions, this configuration prevents lateral movement and twisting during height adjustments or when external force is applied (e.g., typing or leaning on the desk).

Comparison with Other Installation Methods：

Two-Sided Installation: Typically connects the expand beam to the front and back of the lifting column. While sufficient for lighter loads, it offers less lateral stability and is prone to wobbling under uneven weight distributions.

Single-Sided Installation: Common in budget frames, where the expand beam attaches only to the front or back of the column. This design significantly reduces stability and increases the risk of twisting or tilting.

• Know the product weight, not include package.

Heavier frames tend to offer better balance, resistance to wobbling, and overall sturdiness, especially when supporting heavy desktops or equipment. A heavier frame absorbs vibrations more effectively, minimizing wobbling during activities like typing or adjusting the height.

Look for desk frames that weight on 24-25kg(53-55lbs) or more on dual motor 2 stage frame;

Look for desk frames that weight on 28-30kg(62-66lbs) or more on dual motor 3 stage frame;

Look for carbon steel frames, which are heavier and more stable compared to aluminum alternatives, which prioritize portability over sturdiness.

Step 4: Assess the Height Adjustment Range.

Dual motor frames often offer a wider height adjustment range, making them suitable for users of varying heights.

Tips:

• On dual motor 2 stage, the common adjust height(travel) is 480mm(19”) or 500mm(19.7”), based on minimum height 700mm(27.56”).
• On dual motor 3 stage, the common adjust height(travel) is 650mm(25.6”), based on minimum height 600mm(23.6”) or 630mm(24.8”).

Testing:

• Use a measuring tape to verify the minimum and maximum height settings.

Step 5: Evaluate the Control Panel Features.

The control panel is the interface that users interact with most frequently. Its features can greatly enhance convenience.

Tips:

• Memory presets, digital displays, child locks, and timer reminders have become standard features in modern standing desk frames, enhancing convenience and usability.
• The latest trends in standing desk control panels include advanced features like OLED displays for clearer visuals, and USB fast-charging ports (with Type-C being the most desirable for universal compatibility). Backlit designs are also gaining popularity, with RGB adjustable lighting being a top-tier choice for customization and ambiance. For controls, touchscreen panels or buttons with a tactile feel similar to laptop keyboards are considered premium, offering a smooth and satisfying user experience. These upgrades not only enhance functionality but also elevate the desk’s overall appeal.

Step 6: Consider Desktop Size Compatibility.

The common frame expand range is 1050-1800mm(41.3”-70.8”) for 1100-2000mm(43.3”-78.7”) tabletop. Ask supplier, if do customization, whether have extra cost.

Step 7: Look for Safety Features.

Dual motor frames often include advanced safety features to protect users and equipment.

Tips:

• Anti-Collision Technology: Prevents the desk from colliding with objects during adjustment.
• Overload Protection: Stops the motors if the desk exceeds its weight capacity.
• Child Lock: Prevents accidental height adjustments in family or shared spaces.
• Overheating protection: Stop lifting if the motor exceeds the limit temperature.

Step 8: Assess Assembly and Warranty.

The ease of assembly and the supplier’s warranty terms can affect your overall satisfaction with the product.

Tips:

• Choose a frame with pre-drilled holes and detailed instructions for easy assembly.
• Look for a warranty of at least 5 years covering the motors, frame, and electronics.

Testing:

• Attempt to assemble the desk to ensure the process is straightforward.
