Beds are certain number of inches from the ground, usually 18 to 24. While most beds are on frames that leave little room for storage beneath them, only 6 to 8 inches, some wooden bed frames are adjustable. You can raise and lower the height of your bed with these bed frames to create extra storage for your things underneath. The extra storage is great for small apartments or dorm rooms with little space.
