Sleepwell Ortho Resitec HR Foam Mattress – King Size

This Sleepwell Ortho Resitec HR foam mattress in King size (72 x 72 x 5 inches) combines High Density Resitec (HR) foam with a memory foam layer, finished in breathable, anti-microbial fabric. Tuned to a medium-firm feel, it’s built for everyday orthopedic-style support with a focus on staying cooler through the night than typical dense memory foam mattresses.

Breathable Fabric: Why It Matters for Foam Mattresses

Sleep Foundation’s guide to cooling memory foam mattresses notes that airflow plays a meaningful role in how warm a foam mattress sleeps, and that breathable covers and materials can help offset heat retention that’s common with dense foam. The Sleepwell Ortho’s breathable fabric cover is designed with this same goal — helping reduce the trapped-heat feeling that pure memory foam mattresses are known for.

High Density Resitec (HR) Foam Core

Resitec is Sleepwell’s proprietary high-resilience foam technology, engineered to resist sagging and hold its shape better than standard foam over years of regular use. Paired with a memory foam comfort layer, this construction balances structural support with pressure-relieving cushioning at the shoulders and hips.

Anti-Microbial Protection

The mattress cover includes anti-microbial treatment, helping resist bacteria and dust mite buildup over daily use — a practical addition for a King-size mattress that will see consistent, long-term use.
