The bed control functions work fine. I wish it had options for stomach sleepers like myself. The night vision sleep tracker worked once and now no longer works for either side. The app says there is no data. I’ve reset the pumps and setup the beds hoping this would solve the issue but it persists. I called rest and they are aware of the problem and assure me that a firmware update is being developed to address this. I’ll update this review once this issue has been resolved.
