Told on phone could use for other sealy mattresses in store. Huge store carried only the 1 hard as a rock bed & was very tough to get salesperson to show me other Sealy beds that may be available for $650 or less. Only 1 avail and it was pillowtop that felt unsupportive. Only a few other Sealy's avail, but over $1000! Hoping $550 bed will work for guests that all have back problems; if not, lesson learned about doing research before buying or don't by groupon. Other stores had larger selections at reasonable prices. Feel like taken since sold before able to see, hardly any Sealy selection, & no refund policy either. Bed good if don't care who's sleeping on bed & won't use for long.
