Both an ottoman divan and a standard divan have under-bed storage compartments to help you make the most of your room. An ottoman bed lifts to reveal a large storage compartment beneath the mattress, making it better for storing bigger, bulkier items like boxes and bedding in tight-spaced rooms. While a standard divan has drawers installed in the bed base that pull out. This is great for storing small items and clothes; however, there is limited storage space compared to an ottoman bed.
