Inflatable mattresses with cup holder

Cup holder

— a special indentation (or several indentations) where a cup or a bottle/can with a drink can be securely placed. This feature is most popular in chair-mattresses, and some models of inflatable rafts are also equipped with cup holders (see "Type"). However, in more traditional products designed for a reclining position, this feature is almost never found — primarily because drinking while lying down is simply inconvenient.
