How to choose a sit-stand desk that fits your work

What adjustment range do you need?

The adjustment range decides whether the desk suits short and tall users and both working postures. A good sit-stand desk covers roughly 65 to 125 cm, so the desk edge sits at elbow height whether you sit or stand.

The rule of thumb is the elbow rule: forearm and upper arm form roughly a right angle when sitting and standing, and the wrists stay straight. A person of 1.60 m often needs only about 65 cm minimum, while 1.90 m calls for around 120 cm in the standing position.

Electric or manual adjustment?

The drive decides how often the switch actually happens. Electric frames with a motor adjust at the touch of a button in seconds, while manual models with a crank or gas spring are cheaper but the change takes effort and is often skipped in daily use.

• Electric: easier, more frequent switching, memory presets, collision protection.
• Manual crank: robust and low-maintenance, but slower to change.
• Gas spring: fast, yet limited load and a fixed height range.
• Dual-motor frames run quieter and carry more than single-motor versions.

How much load capacity and stability do you need?

The load capacity must carry the whole payload: monitors, drives, lab equipment and the tabletop itself. An office desk with two monitors usually needs 80 kg, while a lab with heavy instruments calls for 120 kg or more.

Stability in the raised position matters just as much. A tall frame sways more, so a wide lifting-column cross-section, three segments per column and a cross-brace all count. Check the maximum sideways deflection at full standing height before placing sensitive devices on top.

• Check payload: the sum of devices, top and accessories stays under the limit.
• Three-part lifting columns offer more travel and higher stability.
• A cross-brace or T-foot reduces sway at standing height.
• Collision protection stops the motor when it meets an obstacle under the top.

What does the right posture switch look like?

The benefit only appears with regular switching. Occupational physicians recommend a dynamic mix of roughly 60 % sitting, 30 % standing and 10 % moving. Instead of long continuous standing, several short standing phases per hour work best.

• Top of the screen roughly at eye level, viewing distance 50‑70 cm.
• When standing, shift foot position slightly; an anti-fatigue mat relieves the legs.
• Flat-soled shoes, do not lock the knees.
• Spread short standing phases across the day rather than one long one.
