The maximum weight load of a height-adjustable desk can vary depending on the model and manufacturer. Generally, most height-adjustable desks have a weight capacity ranging from 50 to 150 kg. However, some heavy-duty models may be able to support even more weight. It's important to check the weight capacity of the specific model you are considering before purchasing, especially if you plan to use it for heavy equipment or multiple monitors. Exceeding the maximum weight limit can cause the desk to malfunction and potentially lead to injury or damage to the equipment.
