If you are buying the twin bed for teen boys, then make sure you select the twin beds that are comparatively longer in length, for example 80 inches rather than the standard 75 inches.
You can choose among the sides left and right where you want to place the drawer considering which side of the bed would touch the wall and which side would be free enough to use the drawers.
For small babies, twin storage beds might be risky as they are 10 to 18 inches off the ground. Climbing and getting off gets tough for young babies. Therefore, consider it a feasible option for teens and adults who need most of their thing within their reach.
Take a measurement of the room where the bed is to be placed. Then also select the area for the bed so that you will have an exact idea of the space available for bed. For a tighter space, you will also have an option of twin bunk bed.
