I bought my Sealy Union LTD Plush Pillowtop II on 7/5/08 thinking I had gotten a great deal. Unfortunately, now my mattress is already showing its cheapness by its lack of resilience. My warranty is void because the box spring wouldn't fit up the stairs and without the box spring that goes with the mattress you are screwed. Sealy doesn't offer a split box spring for this model so I am pretty much out of luck. I won't make the same mistakes again.
