The Black Diamond Hybrid 15" layers a CoolTouch™ Ultra-Cool Cover with Ice Flex Cooling Bands, actively drawing excess heat away for 12+ hours of temperature relief.

Beneath, Cool Titanium Memory Foam contours like traditional memory foam yet adds titanium particles that whisk warmth away, delivering weightless pressure relief without the stuffy feel.

A 7-Series wrapped-coil core floats independently. Each wrapped spring pivots to cradle your shoulders while bracing your lower back.

Moreover, reinforced edge foam widens the usable surface, so you can sit or stretch right to the perimeter.

Finished with a zip-off, machine-washable cover, this 15-inch high-profile hybrid is handcrafted in the USA, backed by a 120-night risk-free trial and a 20-year warranty. All shipped free to your door.

Choose Plush, Medium, or Firm comfort profiles and enjoy motion-free sleep even when your partner tosses.

Key Mattress Benefits

6 Layers
Of Cooling
Comfort

A breathable, zip-off cover pulls excess heat away the moment you lie down. It stays cool to the touch while offering easy maintenance with machine-washable convenience.

Cooling bands extend temperature regulation for longer-lasting comfort. They help maintain a consistently cool surface even during warmer nights.

Titanium-infused memory foam contours closely to relieve pressure at key points. It conducts heat away to prevent the trapped warmth typical of traditional foam.

Transition foam evenly distributes body weight across the mattress. It creates a smooth shift from plush comfort to deeper support.

Individually wrapped coils adapt to different body zones for proper alignment. They reduce motion transfer while supporting the lower back and cushioning the shoulders.

A foam perimeter strengthens the edges for added stability. It expands the usable sleep surface and prevents roll-off.

WE'VE GOT ANSWERS

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Yes. The zoned pocket coils and pressure-relieving Cool Titanium Memory Foam work together to keep the spine in neutral alignment, which can ease lower-back discomfort.

You can choose Firm, Medium, or Plush feels. All three use the same cooling and support technologies.

Absolutely. The Ultra-Cool Cover plus Ice Flex bands draw heat away for over 12 hours of temperature regulation, outperforming standard memory-foam beds.

Any sturdy, flat foundation or adjustable base rated for hybrid mattresses is fine. Ensure center support on Queen sizes and larger. Slats should be ≤3″ apart.

Individually wrapped springs compress only where weight is applied, reducing partner motion and giving firmer lumbar push-back while relieving shoulder pressure. Ideal for mixed and side sleepers.
