Black Diamond vs. Aurora Luxe
Which cooling hybrid wins the 2026 "Thermal Test"?
The Verdict
The graphite/diamond infusion conducts heat deeper and faster than the surface-level GlacioTex of the Aurora.
The Aurora Luxe is often $400-$600 cheaper than the Black Diamond, making it a better pick for budget-conscious hot sleepers.
Diamond's patented zoned coil system provides stiffer lumbar support compared to Brooklyn Bedding's standard coils.

Key Difference: Depth of Cooling
The main difference lies in how they cool you. The Brooklyn Bedding Aurora Luxe relies heavily on its cover. It feels icy cold to the touch, but once you put sheets on it, that effect is dampened.
The Black Diamond, however, infuses conductive materials (graphite and actual diamond particles) into the foam layers. This means the mattress itself acts as a heat sink, pulling warmth away from your core all night long, even through sheets.
Key Difference: Support System
If you have back pain, the Black Diamond is the superior choice. Its zoned coil unit is specifically designed to prevent hip sinkage. The Aurora Luxe uses a more uniform coil system which feels great, but offers slightly less targeted lumbar support.
