You shouldn’t place furniture directly in front of a radiator. The furniture would prevent heat from being distributed freely throughout the room, and could be damaged over time from the close exposure to heat.
You should attempt to leave around 6 to 12 inches (15-30cm) between any furniture and your heating appliance to ensure free movement of air and better distribution of heat.
