I love these bases! Bought to xl twins to push together for a king. They are perfect. Don’t slide. Look nice! Zero gravity is awesome! The message was worth the money!! I have migraines and the vibration helps put me to sleep. Even without the migraines the vibration is like rocking you to sleep! The motor is quiet, adjust well, and very easy to assemble. There is a cool light that turns on under the bed. I have convinced my husband I have magical powers and he has not discovered the button that is clearly marked on the remote.
