This is sold out on Target.com, but here are all adjustable bases from Sears: sears.com/home-mattresses-accessories-bed-frames-adjustable-bases/b-5000615?Product%20Type=Adjustable%20bed&filterList=Product%20Type&searsTab=true
Adjustable bases are to be used in place of a foundation (box spring) mattress. You can use an adjustable base with memory foam, latex, and hybrid mattresses.
Here are all of those types of mattresses: sears.com/home-mattresses-accessories-mattresses/b-5000612?Construction=Hybrid&Construction=Latex&Construction=Memory%20Foam&filterList=Construction&searsTab=true
In the left-hand column you can select your mattress size and firmness.
Hope this helps!
