These outdoor pillows aren't necessarily super comfortable, and they are overstuffed which makes them look smaller... the 16" square looks more like 14", but it's fine.  Obviously not super soft like an indoor pillow, but they are strong and look nice on our outdoor seating. I like the options on Wayfair for outdoor pillows... it took me a while(!!) but it's nice that they have *loads* of pillow options that compliment each other.  I've attached a picture of the whole set we purchased through Wayfair and are very, very happy with our new outdoor living space.
