There are plenty on Amazon. I got one that is nice. I can't find it though, but there are ones like this.
As follow-up, I purchased one off Amazon. It fit the lid fine but offered very little in the way of extra cushioning, making it a near waste of $20. To salvage the purchase I slipped a folded wash cloth inside the cover for extra cushion. That helped a lot. Foam would do the same so will try that when I run across a piece I can cut to fit.
I asked ekr to provide me extra fabric to cover the center armrest and door panel inserts. Not sure if they will provide it because I haven't received my covers yet. From past experiences with the prius, the fabric in the door panel and armerst will wear through very fast.
This is what I've been using for almost 11 months now and it's been great! Super soft and raises your elbow about 3/4-1 inch higher.
