Can the whole cushion be machine washed?

No. The care details say the foam core is not washable. The cover is machine washable in cold water and should be air dried. Do not bleach, tumble dry or iron.

Will it fit my chair?

The listing describes it for standard and compact chairs and gives dimensions, but also presents slightly different measurements elsewhere. Measure your seat and confirm the dimensions and shape for the selected listing.

Is the cushion firm or medium?

The details list medium firmness, while feature copy describes a medium-firm feel. Customer feedback is mixed, with some finding it too firm, so the exact feel may not suit everyone.
