Our Verdict
Tempur-Pedic TEMPUR-Adapt
Novaform Serafina Pearl
The Novaform Serafina Pearl is better than the Tempur-Pedic TEMPUR-Adapt for most people. Both are all-foam mattresses with medium firmness, but the Novaform is more responsive, so it's easier to move around in your sleep, and slightly more cooling. The Tempur-Pedic has significantly better motion dissipation, however.
