Certified Comfort, Backed by Wellness Science

Beyond cooling, SweetNight engineered the CoolNest with full-body alignment in mind. The mattress features ACA-certified 5-Zone Ergonomic Support, a design recognized by the American Chiropractic Association for promoting healthy spinal posture and relieving common pressure points. Each of its five zones provides customized support — softer under the shoulders, firmer beneath the hips, and consistently stable across the back and legs.

The structure maintains balance, prevents sagging, and provides the kind of restorative rest that’s especially beneficial for people who spend long hours sitting or standing —from busy professionals to active families alike.

The CoolNest also meets stringent global standards, including CertiPUR-US OEKO-TEX Standard 100, and ISPA 2025 certifications — ensuring safety, sustainability, and top-tier material quality.

A New Chapter in Affordable Smart Sleep

At the core of SweetNight’s philosophy is a belief that everyone deserves intelligent, healthy sleep — not just those with premium budgets. The company’s focus on self-adjusting technology means that comfort no longer depends on complicated gadgets or hefty price tags.

Every SweetNight mattress is designed around three guiding values:

• Thoughtful Value: delivering smart innovation that meets real needs at fair prices.
• Effortless Health: making wellness a natural part of daily rest.
• Self-Adjusting Care: using adaptive materials that learn, balance, and respond to the body’s needs automatically.

The result is what SweetNight calls affordable intelligence — technology that works seamlessly in the background. For sleepers in warmer climates, that comfort feels both immediate and necessary.
