Will the cushions look flat when they arrive?

Yes. They ship vacuum packed, three per bag, so expect creases and a compressed shape. Give them 24 to 48 hours to expand to full thickness.

Wipe spots with a damp cloth and hang the cushion to dry. The covers are not removable, so they can't go in a washing machine.

Will they fit my patio chairs?

Each cushion is about 18.5 by 16 inches and 3 inches thick, a square shape. Measure your seat before buying; rounded or contoured seats won't match well.

Do the cushions stay on the chair?

Each one has two straps, one on each side, that tie to the chair frame. That keeps them from shifting when people get up and sit down.

Can I use them indoors?

Yes. The same cushion works on indoor dining or kitchen chairs, and the water-resistant cover does no harm there.

Is the foam firm or soft?

The sponge core is described as thick with good resilience, so it holds shape under use. It is a supportive seat pad rather than a deep, sink-in cushion.
