Perfect For

The Integrity Essential Extra Firm mattress works beautifully for stomach sleepers who need maximum support to prevent hip sinking and maintain proper spinal alignment. Similarly, it's ideal for back sleepers who prefer an extra firm sleeping surface with solid support. In addition, those with back pain or heavier body types appreciate the exceptional support provided by the extra firm construction combined with motion-isolating pocket coils.

What Makes the Integrity Essential Extra Firm Special

The Integrity Essential Extra Firm mattress features independent pocketed coils that provide superior motion isolation—each coil is encased in its own fabric pocket, allowing the springs to move independently for personalized support and minimal motion transfer. Additionally, the dual layers of high-density 2.4 weight foam provide exceptional durability and firm support. Furthermore, the 2.4 weight density support foam significantly exceeds industry standards for durability and firmness.

This mattress stands out with its substantial coil count—966 to 2115 coils depending on size—providing exceptional support and contouring even with an extra firm feel. Specifically, this construction ensures the innerspring typically outlasts the padding, demonstrating superior quality and longevity.

All foams are CertiPUR-US certified, meaning they are made without formaldehyde, ozone depleters, mercury, lead and other heavy metals. Foams are screened for relevant chemicals, including flame retardants, that are classified as carcinogens, mutagens or reproductive toxins and are harmful to human health. Moreover, the fire-retardant cover uses a rayon-polyester fiber blend with no topical chemical treatments.

Why Choose Monarch Rest

Unlike mass-produced mattresses, every Integrity Essential Extra Firm mattress is handcrafted by skilled Amish artisans who've perfected their craft over generations. Consequently, you receive a mattress built to last 20 years, not just 5-7 like many competitors. Our foam density specifications exceed industry standards—we use 2.4 weight density foam throughout the comfort layers compared to the typical 1.2 weight foam found in big-box stores. Additionally, the independent pocketed coil system provides superior motion isolation compared to traditional innersprings.

Care & Maintenance

To maximize your investment, we recommend using a mattress protector at all times. Additionally, rotate the mattress head-to-foot every three months to ensure even wear. The single-sided design means no flipping required.
