Wanted to try this because my wife had problems with acid reflux. Amazingly in her case, after 2 months she has not had one problem during the night on this unit. (went on short vacation and had issues on the hotel flat bed) Zero G position is very comfortable. Unit was east to install. Set inside our bed frame with head and foot boards. The package (heavy) was damaged by the transport company, but no damage to the base. Had to get help from customer service to connect to Alexa, but they were very helpful. Alexa works well for most commands and we use it a lot. (cannot turn off the night light- for some reason says turning off massage which is not on) We do not use the massage, but grand kids like it - you might. The bed moves back up to 8 inches as you raise the head to help reach night stands. This helps some, but not that much. (16 inches would be better. Wish we purchased this long ago.
