A shifting elbow tips bedside water onto the edge of the duvet and open paperback.
One scenario to check: A shifting elbow tips bedside water onto the edge of the duvet and open paperback. Notice what your hand was reaching for and what was beneath the container. A drink can be within reach yet still sit directly in the path of that repeated movement.
Arrange the tray while sitting in your usual reading position. Keep the glass outside your elbow and book movement, and move the tray before shifting the bedding. Test the setup with an empty container first. The entire base needs level support.
A sealed container addresses liquid escaping when tipped. A stable surface addresses support. Steadi widens the resting base of compatible drinkware; it does not replace either of those decisions. Check your exact drink fit, then use the guides below for the setup you have.
