Most divans offer the option to incorporate drawer storage. Whether they are located within the sides or the foot end of the base, they offer valuable extra storage for anyone whose space is limited. Storage units do not affect the stability or comfort of the bed, but they do cost a little more.
Storage options on bedsteads are slightly more limited, however most bedsteads by design will have space between floor and under side of the frame which can be use for storing. Alternatively a new innovation is to incorporate an ottoman storage whereby the base and mattress would lift at one end providing storage area under the bed.
