After struggling through a recent sleep-killing heatwave, I've finally managed to get my hands on the CoolNest Memory Foam Mattress, now $399.99 (was $699.99) at SweetNight in the 4th of July sales. The CoolNest Mattress is designed to add cooling comfort to your sleep set-up — but does it deliver on its promise?
The best mattresses on the market typically have some degree of cooling features, as overheating stops you from falling asleep. The CoolNest takes things up a level. A dedicated cooling model, it uses an airflow-boosting cooling cover and heat-dissipating Phase Change Material (PCM) to guarantee a bed that's 8°F cooler than standard memory foam mattresses.
