I may be misunderstanding your question.
The sleep number is basically a high end air mattress. You can get them with different covers of varying thickness. Or you can buy a memory foam topper that just goes over the sleep number although I don't really think you need that.
Don't you need a mattress to go under the sleepnumber and above the box springs still, so they don't replace the actual mattress itself?
