The Sun Rise is a fabulous standup bed with turbo power. It's the envy of all other stand up units. It features a quick maximum exposure schedule and ensures a total body coverage. For your music enjoyment, there is a 3D-Sound system with MP3 dock-in and SD card slot. This allows you to listen to your own mix of music through this acoustically incredible system. You will easily be able to hear music while maintaining a comfortable body temperature thanks to the Sunrise series’ Silent Cooling system. This system bathes the entire body in a pleasant flow of refreshingly cool air, yet is whisper quiet. We have heard it said many times...this is a great standup system.
