After hours spent searching for the best outdoor seat cushions and colors...I went to Wayfair.  The outdoor  high back seat cushions I found at Wayfair were placed on chairs positioned around my fire pit.  They were selected to contrast and compliment the green...yellow...purple...and white flowers represented in my garden.  Couldn't have made a better selection for product and price!      The seat cushions are substantial...sturdy...
easy to clean...plush and comfortable. .  I have to admit that I questioned whether it would work.. II'm stuck on muted monochromatic colors,  but I feel in love with the yellow; and everyone who  spend times in my back yard raves about the beautiful solid yellow cushions with the yellow and white dining table seat cushions with a graphic design (also purchased at Wayfair) and how the entire ensemble compliments my garden!  Everything is bright and happy...so are my guests and me!
