This cushion is not 3.50 inches thick. My old cushion from Wayfair is Sunbrella Outdoor 3.50 inches thick.

I have no idea why these were so expensive. They were the right color and size for me but there is nothing special about them. It took a long time for them to be delivered.

These arrive compressed but do not completely grow into the square shape they are supposed to have at the front of the cushion. The foam inside is not cased in fabric so when you unzip it to try to fluff it, the foam gets stuck in the zipper. I will be sending them back.

Absolute junk, not fit for my dog at the price it was

Quality and exact what we wanted
