Morphology
The meaning 'a cushion that can be filled with air' is directly and transparently derived from combining 'inflatable' (capable of being inflated) with 'cushion' (a soft pad). This adjective+noun compositional pattern is standard and cross-linguistically common, so a B1 learner who knows both constituents will readily infer the MWE's meaning.
Etymology
Inflatable cushion is named from the simple picture of a soft cushion you can inflate by blowing air in and later 'deflate' to make it small. That's why it means a pillow-like pad that gives quick comfort and is easy to carry and store.
