Product Overview

FOLVUTY® PrimeNest™ Black Hybrid Mattress – Graphene-Infused Support, Bamboo Charcoal Fiber Comfort, and Dual Airflow Circulation for Balanced Sleep.

The FOLVUTY® PrimeNest™ Hybrid Spring Mattress is designed for cooler comfort, medium-firm support, and everyday stability. This modern black hybrid mattress features graphene-infused high-density support foam, cooling gel memory foam, egg-crate breathable foam, bamboo charcoal fiber fabric, and individually pocketed coils for a breathable, supportive sleep experience.

Graphene-infused foam helps conduct and disperse heat more efficiently while strengthening the mattress core for stable, long-lasting support. The medium-firm feel balances cushioning and support, while the 7-zone ergonomic support system provides targeted support for the shoulders, back, lumbar area, hips, and legs.

The 14 inch King mattress uses a dual airflow circulation comfort system. Cooling gel memory foam gently contours to the body for pressure-relieving comfort, while egg-crate breathable foam promotes airflow through the comfort layers. Together with the graphene high-density support foam, these layers help reduce trapped warmth and create a cooler sleep surface.

The soft cover is enhanced with bamboo charcoal fiber, offering a breathable, cleaner-feeling, and eco-conscious fabric surface. Over 1,000 individually pocketed coils help reduce motion transfer and improve sleep stability, making this pocket spring hybrid mattress suitable for couples, guest rooms, and master bedrooms.

Made with CertiPUR-US certified foam and OEKO-TEX certified textiles, this fiberglass-free mattress meets CFR 1633 fire safety standards. No fiberglass is used in the cover, foam layers, fire barrier, or inner structure. Compressed as a convenient mattress in a box, it is easy to deliver and set up. Allow 48–72 hours for full expansion.
