In the past few years, we have covered plenty of smart beds and sleep trackers here. The Ensven Smart Bed Rocker is also worth a look. It comes with 4 modules to turn your bed into a rocker to help you fall to sleep and get enough rest each night. Simply lift your bed onto these modules, and you are ready to go. You get two powered modules that move the bed while the other modules balance out the weight.
These rocking modules have a speed of 0.05 to 0.25 Hz and noise level of 25 dBa from 3 feet away. They have max weight capacity of 450lb each and don’t take a whole lot of space (5″ x 15″ x 1.25″).[where to find it]
