When the alarm goes off, the Sfera lowers to hover just above your head and it begins to glow. To active the "sleep" button, you hit it and it retracts a bit toward the ceiling. This continues to happen until it retracts so high that when it goes off, you must stand up to reach it. Then you're up. We don't have that difficult a time getting out of bed, but if you do, the Sfera design is less offensive than the rolling and flying varieties out there.
