the draws (3 set) are not practical. They are small and should be expanded to increase storage space.  The reason i purchased this unit is for storage add-in function, but fail to meet the requirement.       During the assembling, many section of cam fitting units failed to tie up.   They kept falling out when a minor pressure applied from normal bed use (memory mattress expansion).   The cam fitting won;t hold the pressure and loosened /falling out eventually.   I kept repeating the tie-up process, but won't solve.        I purchased two memory foam mattresses, so far so good.
