It fails in real-world conditions, under sustained load, repeated cycles, and environmental variability.  ![Bergad pressure test.](https://hub.bergad.com/hs-fs/hubfs/Bergad%20pressure%20test%20(square)-1.png?width=304&height=280&name=Bergad%20pressure%20test%20(square)-1.png)Compression set is one of the most common issues. Over time, foam loses its ability to recover, leading to permanent deformation. This typically stems from weak polymer structure or insufficient cross-linking. Load distribution is another critical factor. Foam that isn’t engineered across compression depths can bottom out, concentrating stress instead of dispersing it. This leads to discomfort or premature failure. Environmental exposure also plays a role. Temperature shifts can change material behavior, especially in viscoelastic foams, making performance inconsistent. Finally, manufacturing inconsistency introduces variability. Small changes in mixing, curing, or raw materials can create differences that only appear after extended use. Failure is rarely random. It’s the result of foam being specified instead of engineered. When formulation, process, and application are aligned, performance becomes predictable, and failures become preventable.   [![Contact Us](https://no-cache.hubspot.com/cta/default/39829732/interactive-131576374352.png)](https://cta-service-cms2.hubspot.com/web-interactives/public/v1/track/redirect?encryptedPayload=AVxigLIa4%2BY9aV4yt7w8yzosMdjCbNVaNybOWwdf%2BkIWhSuLlg9Q6Ya%2BEv%2FAZu7A1DNHVGCZsd%2Be7o%2BpO2ZRllMGl1zIy%2Bj7vVJ2OJHvXybcineKdPcho0QO0IkvSaaxWCnFAshs8g0Gf95y%2Fcis4%2FUWS6iw5A6D8NSNIuXtXwX%2FXDPG6Q%3D%3D&webInteractiveContentId=131576374352&portalId=39829732) ## Related posts [![](https://hub.bergad.com/hs-fs/hubfs/Screenshot%202023-12-04%20at%2010-38-38%20AM-1.png?height=200&name=Screenshot%202023-12-04%20at%2010-38-38%20AM-1.png)](https://hub.bergad.com/blog/why-spec-sheets-dont-tell-the-full-story) ## [Why Spec Sheets Don’t Tell the Full Story](https://hub.bergad.com/blog/why-spec-sheets-dont-tell-the-full-story) [Chris Hoffman](https://hub.bergad.com/blog/author/chris-hoffman) May 5, 2026 7:00:00 AM Spec sheets are often treated as the objective truth in foam selection.
