What it is
Polyurethane foam mattresses are the largest single-volume segment of the global PU industry. A typical mattress is composed of layers of different types of flexible foam stacked together: an upper comfort layer (often viscoelastic or soft), an intermediate support layer (HR or high-density), and a structural base layer of higher density. Hybrid models combine foam with pocket springs.
Flexible foams for mattresses are predominantly manufactured via continuous slabstock — a process in which the PU reaction occurs in a long continuous line, producing a foam bun that is then cut into slabs and profiled according to the mattress design. Typical densities range from 18 to 50 kg/m³, with most residential mattresses in the 28 to 38 kg/m³ range. Viscoelastic foams have unique behavior — slow recovery, body pressure distribution, "hugging" sensation.
The technology has evolved significantly over recent decades with the introduction of HR foams (high resilience, with special polyols and polymer polyols), viscoelastic foams (with lower NCO index and specific formulation that reduces resilience), foams with infused gel for thermal regulation, and increasingly formulations with bio-based polyols.

Value proposition
Comparison of mattress technologies:
| Type | Comfort | Typical durability | Observation |
|---|---|---|---|
| Viscoelastic foam (memory foam) | High | 8–12 years | Postural alignment, pressure relief |
| HR foam | Medium-high | 10–15 years | Resilience, dynamic support |
| Conventional high-density foam | Medium | 6–10 years | Value for money |
| Pocket springs + foam | Variable | 10–15 years | Ventilation, localized support |
| Natural latex | High | 15–20 years | Premium, hypoallergenic |
Arguments the mattress manufacturer can use with the consumer:
- Postural health: clinical studies demonstrate that mattresses with appropriate density and firmness reduce lower back pain in 50–65% of users with complaints
- Sleep quality: mattresses with proven pressure relief reduce nocturnal position changes and improve REM sleep quality
- Investment ROI: we spend one-third of our lives on a mattress — investing in a good product has a daily cost far lower than other consumer items (roughly BRL 1 to BRL 3 per day over the useful life)
- Low-emission certifications: CertiPUR-US mattresses guarantee absence of harmful substances — relevant for families with children, allergy sufferers and people with chemical sensitivities
- Extended warranties: premium mattresses often carry 10 to 15-year warranties — a clear confidence signal that can be leveraged commercially
Sustainability argument (growing in importance): Mattresses with bio-based polyols (such as soy or castor) and manufacturing processes with lower carbon footprint are a growing differentiator for conscious consumers. Manufacturers who communicate this aspect with concrete data capture share in premium segments.
