Many of these conditions make the variable height feature of a hospital bed a medical necessity. When a patient with debilitating diseases and conditions can control the height of their bed, they can get in and out more easily and without caregiver assistance. Conditions like arthritis can require this feature to allow the patient to ease up off the mattress, enabling them to place their feet on the floor while sitting on the edge of the bed. 

The first aspect to consider is the size of the bedside table in relation to the single bed. A single bed typically measures 90 cm in width and 190 cm in length, which means that the bed sides should be proportional to the bed's dimensions. A bedside table that is too large can overwhelm the space, while one that is too small may seem insignificant or fail to serve its purpose. Ideally, the bedside table should be about the same height as the top of the mattress or slightly lower, ensuring easy access to items placed atop it.
