Our roll + go mealtime mat does not suction to surfaces. Rather, the base is made from a gloss silicone, so it is non-slip and will stay put when rolled out flat onto an even, smooth table surface.
Just make sure to give your hard surface a good wipe and check the bottom of mat for any dust or dirt.
When using, ensure the silicone loop is tucked right in (on the underside of the mat anchor the middle part of the tab then push the sides of the tab in) so that your roll + go mealtime mat sits flat onto your table surface.
If your roll + go mealtime mat has been rolled up for a long period of time, it may need a reverse roll to flatten out again completely.
