This is a foldable single metal bed base and comes with a standard single mattress. Please note that the legs of the base are slightly higher than a standard single bed base so they may not be completely covered by a valance once the bed is dressed. Valances are not included but may be hired separately. PLEASE NOTE THIS PRODUCT IS WHITE (not black as pictured). IMPORTANT: Our beds are for staging purposes only, not for use - comfort is not intended.
