fool me twice. we'll talk, we'll be right back, don't go anywhere. so i go national, where i can choose any available upgrade in the aisle - without starting any conversations- -or paying any upcharges. what can i say? control suits me. go national. go like a pro. with sleep number, there's an adjustment for that. just a swipe to realign your spine. does your bed do that? come into a sleep number store where the c2 mattress is now $699.99. it's a no brainer.
