King: 14 inches high x 76.5 inches wide x 80 inches long.
The steel base bed frame is a steel base that sits up high enough (about 14 inches off of the floor) that you do not use a box spring. The steel base comes un-assembled in a box. No tools are required to put it together. Once built, you simply place the mattress on top and you are ready to sleep. If you want to add your headboard to the frame, you will need to purchase the optional headboard bracket set. Also, if you want to add your foot board to the bed you will have to purchase an additional headboard bracket set that will work for your foot board. Each optional bracket set comes with two brackets.
