I’m having trouble making clean models in SubD. Are there any threads or videos which cover this topic?

Your topology isn’t ideal for refinements. In general, I tend to model everything with quads and avoid triangles or polygons with 5 or 6 corners. Below is an example where I added rings where you need more definition. Also take a look at the corner and the continuity of the edges. As for the creased edge, I creased the segment to the back edge too, that looks better. Even better for a couch which never has a sharp edge would be more dense loops / rings where you want sharper edges.

Thank you. That looks much better. Did you make that from scratch? I guess that is part of my problem, I don’t know how to go from what I had to what you have. I started modeling a polysurf then converted to a mesh then to a SubD.
I edited your model. Deleted some faces and stitched gaps back together, then added detail.
Creating the right topology takes practise.
The internet has a lot of information on topology. Here’s one link:

I’m still struggling a little bit, and I am starting to question whether SubD is the best tool for this application
Attached is the corner type I am looking to create, but no mater how I crease the part I can’t seem to make that occur. I don’t think the corner in your model is bad it’s just a different style.
Unrelated, Is anyone familiar with the math that drives the corner softening? From looking at your part, it looks like the approximate radius of the corner is 1/4 of the distance to the nearest ring from the corner. Is that a safe rule of thumb?
If that’s the look you want to achieve, I’d model it in NURBS
Hi inju
Good idea use Multipipe shape.
Thank’s for sharing~ : )
I tried to mimic the topology of the multipipe you showed. It looks a little better, still need some more refinement.
Unrelated, does anyone have any recommended studies for fairing SubD surfaces? I think I shot myself in the foot with the modeling path I took. The part needs to be removed from a mold so I need a minimum of 1.5deg of draft. I started modeling that way. I’m considering now, that it might have been smarter to model everything square and once I had everything organized and fair, then use a cage edit to add draft.
