The Softbody takes over, and the Skin Deformer is no longer in use. If you take other Simulations, the result is different, but the Hierarchy drives the trouble.

My suggestion #1, use a PoseMorph.

Here, you can use a Collision Deformer result, which can be applied after disabling the Skin deformer. Which might lead to a T-Pose. So, you might want to take a copy and, in the sitting position, set the Binding Pose to new.

Now switch the Skin Deformer off and apply the Collision Deformer to the Character. (If you like to show some impact on Character.) The seat must be positioned within the Collision field of the Deformer.

If the deformation looks right, use the Object Manager > Object > Current State to Object (CSTO) to create a deformed copy. If needed, use the Magnet or Iron Tool to shape the Character's details that come in contact with the chair.

Now, you can switch off the Collision Deformer or delete it. The result of the CSTO can now be used in a PoseMorph. Apply the PoseMorph to the Character mesh and set it to Point mode.

Drag the CSTO result into the field of the Poses. I suggest to use "no" for the Alert. Set the Pose Morph to animation and the Pose slider to zero. Switch the Skin Deformer back on.

Now, you can add the impact of the chair to the Character by animating or just adjusting the slider.
Example:

My suggestion #2: Do the opposite. Deform the Chair Cushion. Typically, the Barcelona Chair is not very soft, but the impact might be visible.
That means the Character becomes the Collision, and the Chair Cushion becomes the Collision Deformer. Explore the Object>Restore Slider value of the Collision Deformer.
Example:
CV4_2025_drs_25_ANdf_01.c4d

Or, a suggestion combining #1 and #2: Of course, for a close-up, perhaps a little bit of example 1 and much more of example 2 might be a good balance. For the quick Solution, use a CSTO of the cushion and sculpt the contact area into the mesh. For animation, use the PoseMorph options. I leave that to you to explore, no example.

All the best

Hi Andrew,

There are four main options to do it.

I have called them Object, Child Constrain, and Weight here, and I'm sure there are a dozen other names available.
The key idea here is, first of all, what fits well into your comfort zone.
I think there is no "best practice" from someone else; it must fit your idea of working. The more you explore, the more options might appear to do the same thing (result-wise). Best practice is, from my point of view, subjective. If one knows only one option, then this is their best practice?

The question is, how do you find what fits?

There is often a split between rigging and animating in Character Animation, especially in studio setups. The one rigging things should do anything that keeps the animator focused on the art of expression, not the art of selecting and moving.

However, if you need the rig only for a single short take, optimizing it would be a waste of time. Therefore, the rigging should be more comfortable.

If the parts of the character (including mechanical) are not final, and the art director or client likes to change things, a very integrated rig might be an obstacle. If the exchange is easy, joints and character are not one large hierarchy, and they have many dependencies on each other (both ways), then the rig with the easiest way to exchange parts will win.
If your character has to move along a larger pipeline or to different apps, then simplicity and standard tools are key.

Yes, I do not tell you what to do or what is best, as this would go against the idea of finding what is best for you and in which circumstances.
You will find a favorite among the four standards and perhaps even mix a new one. I'm sure you will have minimal problems finding what is needed, and then it is yours, not someone else's favorite.

(Of course, Joints have some advantages over other skeleton hierarchies.)

One tip: Always follow the information. With rigs, the Axis of an object might be important to place wisely.

I hope that helps.

My best wishes for your project

Hi Dave,

Do you have none of the cloud services mentioned above?

I can set one up in the morning (Pacific Time). I wouldn't say I like to keep an upload link too long in a post.

I will have a look into it.

All the best

Hi omarpalos,

To work from images doesn't allow for good answers.

Going by what I see, it is a relatively high polygon count, which is not ideal for this task.

My initial question would be, if the points are not altered, how was it moved in this shape? Based on joints, then I would suggest employing the weight map and the joints to move it back. I assume you have thought about that, but I have no information about what you did.

Dragging the new mesh into a Pose Morph that is connected to the initial Object should work, kind of, as the points are "moved" in a straight line or around one single axis. If that works at all, I can't tell based on the images. I suggest placing and aligning the Pose Morph axis where the Toe joint was.

Without any project file, I can't tell more. (If you share it, please as DropBox, Adobe, Apple, Google, or Wetransfer Cloud services. I do not open shortened URLs or unknown services. Thank you.)

All the best
