Case study

Breathable, recyclable baby mattress made from TPU – a Desmopan® AIR case study

NEVEON and Covestro have developed a prototype baby mattress made entirely from Desmopan® AIR TPU. The concept delivers a breathable, washable cushioning solution in a mono-material design, proving the feasibility of zoned comfort, improved hygiene, and simplified end-of-life recycling.

The Material Effect

The Material Effect

Desmopan® AIR TPU granules are turned into layers of breathable, washable cushioning structures using a new extrusion-based process called parallel-layered manufacturing. 

The effect? 

This cutting-edge method enables the creation of mattresses that are easier to recycle while offering enhanced comfort and improved breathability.

Step into the ‘The Material Effect Journey’
Task

Create a baby mattress, demonstrating breathability, hygiene, and circularity

Design a concept-level infant mattress core combining excellent moisture management, tailored support zones, and long-lasting washability. Build it entirely from TPU to enable recycling evaluation, and provide prototypes for lab testing and real-world user trials.

Challenge

Prove recyclability, hygiene, and technical viability in design

Conventional foams trap moisture and are hard to clean; multi-material constructions complicate recycling. The challenge was to design a complete mattress system – outer surface, comfort layers, and internal structure – fully from TPU while keeping it soft, breathable, machine-washable, and suitable for scalable production.

The project with NEVEON showed how material design and processing go hand in hand. By pairing Desmopan® AIR with targeted parallel-layer manufacturing technology and pilot validation, we delivered a solution that meets comfort and hygiene needs and advances circular design for early stage care products.

Solution

Recycling-friendly mono-material design mattress 

Using Desmopan® AIR across all components, NEVEON produced a prototype mattress where cushion layers and functional zones are TPU-based and manufactured in a single continuous process. The design leverages a new production technology, PLM (parallel-layer manufacturing), to engineer airflow channels and create zoned comfort. Covestro contributed tailored material grades, processing recipes, and pilot support, while NEVEON handled prototype production and testing. The all-TPU approach eliminates incompatible adhesives and material joins, paving the way for thermo-mechanical recycling of the entire product.

Working with Desmopan® AIR let us reimagine the baby mattress core: we achieved clear improvements in airflow and washability while keeping the product fully recyclable. That combination is a game-changer for brands and parents who want safe, long-lasting, and more sustainable sleep products.
