Tempur-Pedic Sleep Mask
Utilizing proprietary TEMPUR material, this mask offers a high-density light barrier that molds perfectly to facial contours. It is specifically designed to block light around the nose bridge, a common failure point for other masks.
Quality & Materials
Features authentic TEMPUR material (viscoelastic foam) encased in a soft, dark navy fabric. The foam is CertiPUR-US certified.
Evidence & Testing
The density of the foam is clinically effective at blocking 100% of lux in standard bedroom environments.
Brand Transparency
Tempur-Pedic is a publicly traded company with rigorous quality control and clear material sourcing disclosures.
Value Assessment
Slightly more expensive than generic foam masks, but the material density ensures it doesn't lose its shape or light-blocking efficacy over time.
Why Not Alternatives?
Most 'memory foam' masks use low-density polyurethane that degrades quickly or off-gasses; Tempur-Pedic uses genuine medical-grade viscoelastic foam that provides a superior light seal and longevity.
