Brooklyn Bedding ThermoBalance

The Brooklyn Bedding ThermoBalance arrived with a lot of hype around its cooling tech, and after 30 nights of testing, I can say it largely delivers. The ThermoCool cover feels noticeably cool to the touch — not the fake 'cool for 5 seconds' you get with some cooling covers, but a sustained temperature regulation that I could measure with our thermal imaging camera throughout the night.

Brooklyn Bedding has a unique advantage as one of the few mattress brands that owns their own factory in Phoenix, Arizona. This factory-direct model cuts out middlemen and keeps costs lower than you'd expect for a mattress with this much cooling technology. The build quality reflects that manufacturing expertise — seams are tight, materials feel premium, and the 8-inch Ascension coil unit provides excellent support with minimal noise.

The copper-infused HD 4.0 memory foam is a standout layer. Copper naturally conducts heat away from the body and has antimicrobial properties. Combined with the ThermoPhase change material (which actively absorbs excess heat), this is the most effective passive cooling system I've tested — rivaled only by the Eight Sleep Pod's active cooling, which costs 3x more.

My main criticism is the 120-night trial period. In an industry where 365-night trials are increasingly common, Brooklyn Bedding's trial feels conservative. The 10-year warranty is also shorter than competitors offering lifetime coverage. That said, the mattress itself is outstanding for hot sleepers, and the multi-firmness options mean you can dial in exactly the right feel.
