The soft, flexible arm can be attached to both flat and round surfaces via the sturdy clamp which opens to nearly 10cm (4'). Once attached, the colourful, non-toxic foam arm can be bent a full 360° in any direction to place the insulated holder in the desired location. The holder employs a hook and loop strap to accommodate different size cups. Attaches to strollers, car seats, play yards, tables and other surfaces. Latex free.
