My wife and I previously owned an i10 king-size, Sleep Number bed(top of the line at the time of purchase) before purchasing our split-king size with 3″ boxtop iSleep bed. Immediately upon inspection of our new iSleep bed, I noticed the quality of materials and workmanship, which by far is superior to the Sleep Number bed we owned. We also have better support with our new iSleep mattress than we did with the Sleep Number bed. It did take my wife and me a while before finding the right setting, but once we did-Awesome, Comfortable, Supportive, Restful Sleep!
