Foam:

Clarification: Our mattress topper foam is engineered with advanced cooling technology to enhance sleep comfort by effectively regulating temperature. Each topper incorporates specific materials that contribute uniquely to its cooling capabilities:

• Gel Topper: Infused with gel beads, this topper absorbs and dissipates heat, maintaining a cooler sleeping surface throughout the night.
• Copper Topper: Features copper flakes known for their high thermal conductivity, which helps draw heat away from the body.
• Super Topper: A combination of both gel beads and copper flakes, this topper maximizes the cooling effects by harnessing the benefits of both materials, offering superior temperature regulation.

Reference:

• Cooling Properties of Gel Beads: For insights into the thermal regulation properties of gel-infused memory foam, see "Thermal Regulation Properties of Gel-Infused Memory Foam," published in the Journal of Sleep Materials, Vol. 5, No. 3, 2021.

CoolTech Covers:

Clarification: Our CoolTech Classic and CoolTech 2.0 covers are meticulously designed to enhance the cooling effect of our Copper and Gel mattress toppers. Composed of a proprietary blend of Polyethylene and Polyester, these covers are engineered for optimal thermal regulation and comfort.

Polyethylene is known for its ability to facilitate heat dissipation, making it an ideal material for cooling. Combined with polyester, which adds durability and moisture-wicking properties, the CoolTech Classic covers ensure a cooler, more comfortable sleep environment.

Clarification: Our mattress toppers are designed with copper-infused technology that harnesses the natural antimicrobial properties of copper to provide odor resistance. Copper's ability to disrupt the growth and survival of bacteria and other microorganisms that cause odors ensures that our mattress toppers maintain a fresher, cleaner sleeping environment.

Reference:

• Research shows that copper oxide nanoparticles incorporated into textiles, such as our mattress covers, exhibit strong antimicrobial properties that prevent the growth of odor-causing bacteria and fungi. For detailed studies, see Luz E. Román et al., 2020, which discusses the antimicrobial properties of copper oxide nanoparticles in textiles.
• Further evidence of copper’s antimicrobial efficacy, which directly contributes to odor resistance, is provided in the review by I. Salah, I. P. Parkin, and E. Allan, 2021, outlining how copper disrupts microbial cell membranes and prevents biofilm formation.

Clarification: Our mattress toppers are designed to resist mite infestations, enhancing sleep hygiene and comfort. The mite-resistant property of our toppers is achieved through the integration of copper oxide in the fabric. Copper oxide has been scientifically proven to reduce the survival and mobility of house dust mites significantly, making it an effective material for mitigating allergen exposure in bedding.

Reference:

Mumcuoglu, K. Y., Gabbay, J., & Borkow, G. (2008). The study, titled "Copper oxide-impregnated fabrics for the control of house dust mites," published in the International Journal of Pest Management, demonstrates the effectiveness of copper oxide in reducing house dust mite populations on treated fabrics. The research found that fabrics treated with copper oxide showed significantly higher mite mortality rates compared to untreated fabrics, proving the acaricidal properties of copper oxide.
