Foam, sponges and cushions

Deformable sofa cushion

A deformable seat or sofa cushion, modeled as an FEM foam body with a fabric cover for home tidying robots.

Also called couch cushion, throw cushion or seat pad.

How is the deformable sofa cushion modeled?

A sofa cushion is a firm foam core in a fitted fabric cover. We model the core as a volume and the cover as cloth around it, with piping as a stiffer band along the edges.

Cushions are heavy for their size and bend only a little, so they are lifted and placed rather than folded.

Which parts of the deformable sofa cushion deform?

Foam core
Firm volume that compresses under weight
Cover
Fitted cloth with piped edges

What ships in the USD?

One USD file per variant, with the render mesh, the simulation geometry and a physics material bound to it. Every value is set and named, so you can open it in NVIDIA Isaac Sim and run your task, or read the numbers into your own solver from the material JSON.

  • FEM soft body. A tetrahedral volume solved with the finite element method, with the visible surface carried by it. Used for foam, rubber and soft food.
  • Cloth. A triangle surface with stretch, shear and bending stiffness and a thickness. Used for towels, sheets and garments.

Where is it used?

  • Tidying a sofa
  • Placing cushions
  • Home navigation obstacles

Industries: Household, Hospitality

Questions

Which simulators does the deformable sofa cushion open in?

It ships as USD for NVIDIA Isaac Sim and Newton. We also deliver MJCF for MuJoCo and Genesis, a GLB mesh, and a JSON file with every material value.

Can it be matched to our real object?

Yes. Send us a sample, a drawing or a few photos and we set size, stiffness and friction to match your part.

How do we get it?

Choose your simulator, format and variant, then tell us where to send it. We prepare the files and email them to you.

Not in the catalog? We build any object to order, with the same physics and delivery.
