We have had the SmartLife, Lilly Medium for about a year now. The auto-sensing and adjusting does not happen in real-time, it only adjusts every so often.
However, for the price of this bed my main criticism is that the app is very limited and could do much more but has never been updated. You can only adjust the firmness from 1-9 and there does not seem to be a lot of difference between the settings. Since there are 8 zones and 40 smart cells per side, it would be nice to be able to customize the firmness per zone, and even per smart cell using a map of the bed and body that senses where a body is currently laying on it.
The massage mode should have the ability to select a specific time increment (dial/wheel), instead it is limited to 5, 10, 20 or 30 minutes.
Finally, an Apple Watch app with some basic controls would be nice:
1. Turn on relaxation mode with a dial/wheel control for duration.
2. Adjust firmness
3. Wake up alarm settings
4. Automatic pressure relief on/off
