Pinched corners - Network Surface

Hello everyone, I am creating a chair that cannot be shared as of now, but I am hoping to receive any tips or insight with what I can provide. I am creating this chair’s surfaces via network surface, which I use often, but I am facing a lot of pinching and creasing happening throughought. I am no Rhino expert and learning a lot during this project, so I’m hoping to understand why this is happening and how I can resolve it. Please refer to the images I have shared. Thanks so much!

Hello - it’s hard to say without a file but think about making the surfaces simpler and if needed, trimmed to the shape you need so you don’t get that UV pinch where the two surface directions become parallel.
