The Joerns PVAL-4280FLTM4SZP PrevaMatt® Alleviate is an ultra-premium, SEO-optimized bariatric therapeutic surface that combines a generous 42-inch width with genuine TEMPUR® material. This "Flat" model is specifically engineered for larger residents at high risk of skin breakdown, providing advanced immersion and envelopment to prevent and treat up to Stage 2 pressure injuries (and up to Stage 3 uncomplicated injuries with the TEMPUR® upgrade).

Encased in a 4-way stretch, low-shear cover with an integrated fire barrier, it is fluid-proof and antimicrobial, making it a high-performance choice for bariatric-ready clinical environments.
