Nightstand height depends on the height of your bed and your personal needs and preference. The easiest way to determine the optimal height is to measure from the floor to the top of the mattress and choose a nightstand within three inches of that height, either higher or lower. Think about the items, such as a night lamp or alarm clock, that you will put on the nightstand so that their positioning is within convenient and comfortable reach. Kouboo's nightstand height ranges from 20 to 24 inches.
