I have purchashed the mattress and box spring came free . I have fibromyalgia and a lot of sleep issues . I am not sure if I will upgrade to the movable frame but glad I have the option , it seemed to put more pressure on my pressure points but that's just because of my fibromyalgia . It is a very comfotablee bed laying flat for me . I also know that I don't have to go to a mattress store to get either product and was happy I saved more on my mattress and the movable frame is $200 less so its still in my budget.
