Rize Comtemporary III is wonderful for my back! The lumbar support on this bed is phenomenal!! This is the best feature to me of all the features it has. The massage is just ok. It’s a bit loud and is upper body only. I guess they had to eliminate one of the massage motors for the lower body (there is a place for a second motor to plug in on the control box) in order to provide the lumbar support. But like I said, the lumbar support is far more important to me than a full body massage. My only complaint is the remote. Although the buttons light up, the lettering does not. So until you memorize which button does what, it is a bit hard to navigate in the dark. Thank you to whoever designed this bed. My back and I love you!

My biggest worry buying an adjustable bed was the weight capacity and how solid the frame was. I am a large man, 277 pounds. It makes no noise, no squeaks, it doesn’t move on the floor, when I’m getting in and out, or moving in bed. This bed frame is solid. It sits me up and lays me down quietly. I overuse its features because of my spinal injury. I’m impressed and satisfied with my purchase.
