Gray Open-Cell Breathable Memory Foam

Key Specifications

The gray open-cell breathable memory foam uses advanced micro-cell open-cell工艺, achieving an open-cell rate above 95% with over 2 million micro-pores per cubic centimeter. Density: 80D; rebound time: 3-5 seconds. It combines the contouring comfort of slow-rebound foam with the breathability of an open-cell structure. Breathability is approximately 3x that of standard memory foam, ensuring continuous air circulation within the foam.

Open-Cell Structure Explained

Unlike traditional closed-cell memory foam, the open-cell工艺 creates a 3D interconnected airway network inside the foam. Each micro-pore is an independent breathing channel — when you lie down, body heat and moisture don't get trapped inside but diffuse outward rapidly through the dense pores. The gray color maintains excellent breathability while presenting a understated, sophisticated look for minimalist-style users.

Breathability Performance in Testing

In a 35°C simulated environment test, the gray open-cell memory foam's surface temperature rose only 1.2°C after 5 minutes of contact, compared to 3.8°C for standard memory foam. The open-cell structure effectively reduces heat buildup, keeping users cool and dry all night. Paired with a breathable pillowcase, the cooling effect is even more pronounced — ideal for summer use and heat-sensitive sleepers.

Durability & Quality Assurance

After 100,000 compression-rebound cycles, the gray open-cell memory foam shows less than 5% deformation, and the open-cell structure does not collapse or close with long-term use. SGS eco-certified, free from formaldehyde and harmful chemicals, safe and odorless. Backed by a 3-year warranty for peace of mind every night.
