| 1 | Adjustable Working Angle | Look for at least 3 stable positions, including a near-vertical position and a lower angle of approximately 45° or less. | Change the angle with a board or canvas installed. Confirm that the support does not slip or wobble. | High | Different angles support drawing, painting, glare reduction, and comfortable posture. |
| 2 | Canvas Height and Size Range | Choose a height range that suits the user and supports the intended artwork. A useful general-purpose range is approximately 60–150 cm for the working height. | Compare the listed maximum canvas height with the largest canvas normally used. Check whether the lower ledge can be repositioned. | High | Correct sizing prevents overreaching and keeps the artwork securely supported. |
| 3 | Base Stability and Weight Capacity | Prefer a broad footprint, non-slip feet, and a stated load capacity that exceeds the combined weight of the canvas, board, and wet media. | Place the easel on a hard, level floor and apply light pressure from several directions. Inspect joints, braces, and leg locks. | High | A stable frame reduces vibration, protects wet work, and improves brush control. |
| 4 | Wood Construction and Finish | Check for straight, kiln-dried or well-seasoned wood, smooth edges, tight joints, and a protective finish without exposed splinters. | Run a cloth lightly over the frame, inspect the corners, and look for cracks, warping, loose screws, or uneven surfaces. | Medium | Quality woodwork affects durability, safety, appearance, and resistance to seasonal movement. |
| 5 | Portability and Carry Weight | For frequent transport, consider a lightweight frame of roughly 3–7 kg, provided it still offers adequate stability for the intended artwork. | Check the listed net weight, carry handle, and whether the folded unit can be moved comfortably with one hand. | Medium | Lower weight makes studio changes, workshops, exhibitions, and outdoor use easier. |
| 6 | Folding and Storage Dimensions | Compare folded length, width, and thickness with the available storage area. A folding design should close securely without requiring excessive force. | Measure the storage space first, then verify that the folded easel fits through doors and can stand or lie safely in storage. | High | Compact storage protects the easel and helps maintain an organized workspace. |
| 7 | Locks, Hardware, and Maintenance | Look for secure knobs, wing nuts, braces, hinges, and replacement hardware. Wood surfaces should be kept dry and periodically checked for loosened fittings. | Open and close every adjustment point several times. Confirm that locks engage fully and that hardware is accessible for tightening. | Medium | Reliable hardware improves safety and extends the service life of the wooden frame. |
