The short answer

Choose fixed feet for a guest-room desk that stays put for daily work and only needs to move occasionally; choose castors only when the desk maker supplies them for that model, you regularly clear the room for guests, and the castors can be secured or the desk is designed to stay stable while you write. The trade-off is easy repositioning against possible movement and floor wear.

What to check before deciding

How often will the desk actually need to move?

Start with the room’s switching routine. If the desk must be pushed aside whenever a guest bed is unfolded, castors may save daily dragging—but only if the route is clear and the maker confirms the desk is meant to move as assembled. If the room converts only for occasional visits, or the bed can be set up without shifting the desk, fixed feet avoid a moving part you do not need. This advice does not apply when the desk is required to stay anchored or when its instructions prohibit moving it.

Which stability and floor-protection details decide it?

Stability comes from the whole desk and the specified castor, not from the word “castor”. Ask whether the castors are part of the exact model, whether they can be locked, and what floor surfaces they are intended for; a photographed castor may be an accessory. On a rug over hard flooring, check how the castor crosses the edge. If those details are unavailable, fixed feet with the maker’s specified glides are the safer selection, provided the maker permits them.

A practical checklist

  • Count how often the room must switch between work and guest use, then watch where the desk would travel. A short, clear route supports castors; repeated lifting over rugs or thresholds argues for fixed feet.
  • Ask the seller to confirm castor inclusion, locking method, intended floor surfaces and whether moving the desk loaded is permitted. Do not infer these from a product photo.
  • Before any move, clear the desktop and follow the desk maker’s moving instructions; check the path for rug edges, door frames and cables rather than dragging the desk through an unseen obstacle.

These are general planning ideas. For an individual product, confirm its exact dimensions, care instructions and installation requirements.
