  • Titanium-Infused Memory Foam engineered to help dissipate heat while providing contouring comfort
  • Ice Flex Cooling Bands designed to promote airflow and assist with temperature regulation

Pressure-relieving materials are designed to contour to the body to help reduce pressure points and provide enhanced comfort and support.

  • CertiPUR-US® certified comfort layer for cushioning comfort and supportive contouring
  • Individually pocketed coils designed to provide targeted support and help reduce motion transfer

Core support components are designed to provide foundational support, promote proper spinal alignment, and enhance overall mattress durability.

  • Foam-encased construction for reinforced edge support and a more stable sleep surface

Certifications
Diamond Mattress mattresses are designed to meet rigorous certification standards and are made with fiberglass-free materials. All foams used are CertiPUR-US® certified, meaning they are tested for certain harmful substances, emissions, and durability standards. Select mattresses also hold GREENGUARD Gold certification, which tests for low chemical emissions to help support improved indoor air quality.

These certifications reflect Diamond Mattress’s commitment to using materials and manufacturing processes designed to support a cleaner and more comfortable sleep environment.

Set-Up and Care Instructions

1. Unboxing and Placement

Move the compressed mattress to your bedroom before unboxing. Place the rolled mattress onto your bed frame or foundation. The DM Black Diamond is a heavy, high-profile 15-inch hybrid; we recommend two people for lifting and positioning.

2. Decompression Process

Carefully remove the outer plastic wrap using a safety cutter or scissors, taking care not to puncture the fabric. Once the vacuum seal is broken, the mattress will begin to expand immediately.

  • Expansion Time: While the mattress may look ready within minutes, allow 24 to 48 hours for the hybrid layers and pocketed coils to reach their full 15-inch loft and structural integrity.

3. Off-Gassing (New Mattress Scent)

Because your mattress is freshly manufactured and sealed for shipping, you may notice a "new mattress" scent. This is normal and non-toxic. Simply keep the room well-ventilated for the first 24 hours to allow any odors to dissipate.

4. Proper Support Requirements

To maintain your warranty and prevent sagging, ensure your mattress is placed on a supportive surface:

  • A sturdy platform bed.

  • A high-quality foundation or box spring.

  • A slatted frame with slats no more than 3 inches apart.

Returns are allowed for damage during shipping and all issues that align with the warranty policy.

What people like

This mattress provides an exceptionally cool and supportive sleep experience, frequently praised for its innovative temperature regulation that effectively manages heat for over twelve hours. Users appreciate the combination of a plush, quilted Euro-top for immediate comfort and a robust coil system that provides deep structural support and pressure relief. It is often described as a high-end alternative to more expensive luxury brands, offering a balanced medium feel that accommodates a wide range of sleep positions. The high-quality construction and attention to detail, including reinforced edges and motion-dampening coils, contribute to its reputation as a premier choice for restorative sleep.

Pros

  • Exceptional Cooling Technology: The inclusion of specialized cooling bands and a cool-touch cover ensures the surface remains at a comfortable temperature throughout the night.
  • Premium Pressure Relief: A thick quilted Euro-top works alongside high-density foam layers to cradle the body and reduce tension on sensitive joints.
  • Minimal Motion Transfer: The individually wrapped coil system effectively isolates movement, making it an excellent choice for couples who do not want to disturb each each other.
  • Strong Edge Support: A reinforced perimeter allows users to sleep right up to the edge of the mattress without experiencing a "sliding off" sensation.
