Well, I just ordered a Sleep Number! I got a mail-out from them, and they're having a Demo Bed clearance. Basically, its demo beds, floor samples, first-quality returns, and refused shipment deliveries. They state: "We fully inspect each internal component. Then we produce brand new mattress fabric coverings." Basically, it's a like-new mattress. They do come with the 20 year limited warranty, but the 30-day in-home trial is not available for these beds. The only beds offered are the c2 and the p5. FYI, foundations are optional. Here are the prices:
c2
Twin - $299 Foundation - $169
Queen - $449 Foundation - $229
King - $699 Foundation - $339
p5
Queen - $999 Foundation - $229
Exp. Queen - $1,099 Foundation - $269
