Buyer rule
Start with the body-to-desk fit
Start with power-strip location, standing-desk travel, monitor-arm movement, tower service access, chair path, and which cables need slack instead of tight routing.

Cable tray ergonomics
Cable management is part of ergonomics when it decides whether the chair rolls freely, the standing desk moves safely, the monitor arm has slack, and the tower can be serviced without dismantling the workstation.

Risk
The common mistake is making cables look tidy while trapping the GPU tower, over-tightening display cables, or putting power bricks where knees and chair wheels hit them.
Amazon ergonomics and desk lanes
Use these lanes after the chair height, monitor position, desk depth, keyboard reach, mouse path, lighting, cable slack, and tower location are specific. Amazon has the live listing details, seller terms, shipping, returns, and exact product specifications.
Primary cable lane for power strips, adapters, docks, and bundled desktop wiring.
Wall and desk-edge lane for clean routes between monitors, docks, towers, and outlets.
Movement lane for sit-stand desks where power and display cables travel with the top.
Reachable-power lane for chargers, lamps, docks, and temporary hardware without crawling under the desk.
Service lane for identifying display, USB, Ethernet, and power cables during GPU swaps.
Chair-path lane for cables that must cross a walking or rolling path.
