Use wheels only for a real room constraint
Casters earn their trade-offs in a shared room, rental, or cleaning-heavy setup where the desk must move. If the desk stays parked, fixed feet usually protect seated height and stability better.
Add caster height before checking fit
Wheels can raise the lowest desk position. Compare the finished keyboard height with seated elbow height rather than relying on the frame's number without casters.
Lock every wheel before working
Test rolling, braking, and frame movement on the real floor. A wheel that works on hard flooring may behave differently on a rug or soft mat.
Move the cable system with the desk
Secure the power strip to the moving desktop when appropriate, preserve one safe path to the wall, and keep cable loops away from wheels and feet.
Heavy monitors reduce the benefit
A long monitor arm and heavy display increase visible movement and leverage. Keep the screen near its post and reconsider wheels when display stability is the main priority.
