The Side Cradling Sleeper(R) brings comfort to side sleepers by supporting the torso to better align the spine and relieve the pressure on the shoulder. Get the feel of a $5,000 mattress for about 1% of the cost. Our studies show up to 20% better sleep when using the Cradling Sleeper, and weve received great reviews from people with sore shoulder and rotator cuff injuries. Pregnant women have tried it and said it has helped them sleep comfortably. Weve also had customers use them in cars and airplanes for added lumbar back support.
