Here are the conditions to check for your desk:
Tabletop Material: If your desk is made of any of the following materials, or if the surface is prone to denting or includes glass, we recommend using a reinforced plate such as BenQ BSL / BDL01 (reinforced version) or an additional third-party reinforcement plate for installation:
.Hollow tabletop
.Honeycomb boards
.MDF (Medium Density Fiberboard)
*Tabletop Thickness: The tabletop thickness must be between 1 cm and 5 cm.*
In summary, if your desk has a tabletop material that is prone to damage or is hollow, it is recommended to use a reinforcement plate for proper support.
