Of all the remote controls that should light up in the dark, the one for the Tempur-pedic bed is a natural. And it does light up, nicely, but unfortunately, there is no way to turn on its light without triggering a command. This is an unfortunate design choice.
The only command that you can quietly activate, without moving the bed’s mechanics, is the under-bed lighting system. But finding this single button in the dark is a challenge, particularly if you’re not fully awake.
My solution comes courtesy of Japanese discount store Daiso. A small adhesive stationery adornment provides the tactile locator that Tempur-pedic forgot.
