Test footage of our auxetic foam under load

Foam that pulls in under pressure.

Zetic® is our patented auxetic polyurethane foam. Press it and it draws material toward the load instead of spreading out. We make it in one foaming step at industrial scale, and it is already on the market inside Huggah® mattresses.

Watch the sides as the load goes on

Ordinary foam bulges outward when you press it, so material moves away from the point that needs support. The cells in Zetic® foam fold inward and gather material under the load. The harder the press, the firmer the support, all from a single layer.

Two foam samples under the same press. The conventional sample bulges outward; the Zetic sample narrows inward.

Zetic® foam

  • Wider when stretched

    Zetic® is auxetic: stretch it and it gets wider, where ordinary foam gets thinner. That is what a Poisson's ratio below zero means.

  • Open-cell structure

    The thin walls between Zetic® cells are open, so the cells connect and air can pass through the foam.

  • Made in grades

    Zetic® can be made in different grades: formulation and process set each grade's density, firmness and how strongly it pulls in.

Auxetic foams in published research

  • Curves into a dome

    Bend a sheet of auxetic foam and it curves into a dome, where ordinary foam forms a saddle. This synclastic curvature can help it wrap rounded shapes.

  • Resists indentation

    Under a load on a small area, auxetic foams draw material in beneath it, and lab studies report this can make them harder to press into.

  • Impact research

    In published low-energy drop tests, auxetic foams recorded lower peak forces than the ordinary foams they were compared with.

Made in one step, at industrial scale

Auxetic foam was first made in a laboratory in 1987, by compressing, heating and cooling ordinary foam one sample at a time. The method was slow, costly and limited to small pieces, so the material rarely left the lab.

Our patented process forms the auxetic structure while the foam is being made: one foaming step on standard equipment, producing full-size blocks. It took nearly a decade of work with Prof. Ruben Gatt and the Metamaterials Unit at the University of Malta, and more than 5,000 trial batches.

Huggah: The first application of Zetic® technology

The mattress that hugs you back.

Huggah® is a mattress built around a single adaptive Zetic® core, in place of the stack of glued foam layers inside a typical premium mattress.

  • In Malta since December 2025
  • 100-night home trial
  • 10-year warranty

Where Zetic® foam goes next

Mattresses came first because we can test the material directly with the people who sleep on it. Every other use will need its own grade of Zetic®, adjusted and tested for that application. We are looking for partners in each of these fields to develop those grades with us.

The team behind Zetic®

Smart Materials was founded in Malta in 2020 to take auxetic foam from the laboratory to industry. Our founders bring together materials science, engineering and commercial experience, and our lab and production line are in Qormi.
