Key item features

  • Graphene-Infused High-Density Support Foam: Reinforces the core, improves structural stability, distributes body heat evenly, and resists sagging for consistent, long-term performance.
  • Dual Airflow Circulation System: Gel-infused memory foam paired with egg-crate breathable foam relieves pressure while promoting airflow, keeping the mattress cooler and drier throughout the night.
  • Individually Pocketed Spring Dynamic Isolation: Over 1000 pocketed springs respond independently to body movement, reducing motion transfer and providing a quieter, more stable sleep surface.
  • King Size Mattress Versatility: Perfect for master bedrooms, guest rooms, or shared spaces, offering firm, supportive, and cooling comfort every night.
  • 7-Zone Ergonomic Support: Denser coils in lumbar and center areas maintain spinal alignment, while softer shoulder and hip zones reduce pressure, supporting back, side, and combination sleepers.
  • Certified Safe, Fiberglass-Free Construction: Made with CertiPUR-US certified foam and OEKO-TEX certified textiles, this mattress meets CFR 1633 fire safety standards. It is fiberglass-free throughout the entire mattress, and low-emission materials for a healthier sleep environment.
  • After-Sales Guarantee: Includes a 120-night trial, 10-year warranty, and 24-hour customer support for confidence in comfort, durability, and long-term use.

About this item

Product details

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.

My first time purchasing a mattress in a box. I'm impressed. It was delivered on time and boxed very well. It was heavy and I required assistance to get it inside. Just follow the instructions and allow it time to inflat. Mattress was at a great price and is very firm. Hopefully it will last a long time, time will tell. Currently recommended.
