@Rich-O-Brien flowify is the key for this sort of stuff..

It would help to see the workflow for that last especially, if/when you have time.

@Mike-Amos well, in this case i started with a basic trace of photo references, I use components, so that I can use different photos for different pieces but then the components are nested in the main assembly so they end up in the right place..

They also gave me a pretty bad photoscan, so I used that just to intersect it with a plane and extract the basic profile of the seating.
I then smoothed the extracted curve with Curvizard and normalized it with Polyline Segmentor

Then I created a base grid for the pattern with the proper real world measurements.

I then created a repeated component with Curviloft Skin

Same for the buttons

And then create a different variation of that component for the sides

And another variation for the corners

then I joined all of them together.. please notice that In this stage I try to keep the quads as even as possible, because I'm gonna deform this stuff

Then I extracted the diagonals for the sewing and used "Lines to Tubes" with quite low poly geometry.. and of course I did some cleanup with quadface tools for the overlapping geometry which will not be seen.

I then created the base shape of the seating using Curviloft ad Quadface tools.. and extracted the grid were I need the upolstered thing..

Then I use the QuadfaceTools "Unwrap Grid" feature to extract a flat grid from that.. which has the exact same lenght and topology of the seating that I'm going to replace.. and here is the flowify rig setup that I used to send the geometry to the curved surface.

WARNING: you need to use "flowify without cuts" to avoid messy topolgy and keep quads.

From this stage, it was just a matter of stitching and tweaking.. with the usual VertexTools, QFT, Artisan shenanigans

Meanwhile I also added the studs.. I used profile builder assembly to place them and then manually repositioned some bits in the problematic areas

And this is the updated version with the studs..
I hope this was helpful to better understand the process..

It's a bit different every time.. the shoe and the skatepark used a quite different process.. and the other sofas I posted before of that, is another different story..

A Great work! – & thanks for the many pictures of the doing process.

Agreed, a great resource. Thanks very much for that.

I improved the upper stitching (which was too hard compared to the reference) with Vertex tools and the upper part of the tuft (which was too thin) using Artisan2 FFD (with a couple of tricks to make it work on multiple subgroups).
I also increased the rounding of the frame profile using Artisan Move tool "normal" constraint.
I think I'm done with this one.
Time to unwrap it

Another WIP from the same vintage furniture job, leveraging the power of components..
Most of the armchair details are reusable for the sofa.
