Have you asked the designer ? She seems to be active and answering other questions for people on Houzz..

Wow - I have never had much luck asking questions on Houzz, but got an almost immediate response back....Kravet!

That's what I was going to suggest, contacting the designer who did the room.
Otherwise, you could also do a search for ogee upholstery fabrics, ogee prints.

Jonathan Adler has some ogee pillows in his line

For that same soft color combo see the Judy Ross textiles -
A bit higher $ range as custom from a workroom.

Or the Liora Manne collection for something more affordable - available on Wayfair and amazon and less than custom pillows would be from any workroom.

Kellie, isn't it nice when designers participate fully on Houzz. I've been known to call out those that complain they don't have the time to answer questions. My reply, save even more time and don't post your photos! When I interviewed IDs last year one of my criteria was that they were active participants on Houzz by answering questions about their projects. I will also look up product details when the designers keep saying it was "custom" and you can purchase it through them. Yes, it will most likely be to-the-trade, but not so unique that people can't find a local source/designer to order for them once they have the details.
