Deformable mattress topper

A deformable mattress topper, modeled as a large FEM foam layer for bed making and hotel robots.

Also called mattress pad or foam topper.

FEM soft body

Delivered as USD for NVIDIA Isaac Sim

How is the deformable mattress topper modeled?

A topper is a large, thin foam layer that sags when lifted from one edge. We model it as a volume with soft foam stiffness, sized to standard beds.

It is heavy and awkward, which is the point: it tests two-handed and whole-body handling.

Which parts of the deformable mattress topper deform?

Foam layer: Large soft volume that sags and folds

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.

Where is it used?

Bed making
Handling large soft items
Hotel housekeeping

Industries: Hospitality, Household, Healthcare

Questions

Which simulators does the deformable mattress topper 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.
