Standar set of Serta/Simmons Boxspring, 5" steel frame. A King boxspring comes in two pieces, which are two TwinXL's that you put together to make one King. Since we get everything as overstock all of our boxsprings come in all different colors. If you are buying a mattress and boxspring we will try to match them up but it all depends on what we have at the time. All boxsprings are the same quality the only difference is the color. Thanks for understanding!
