Will it smell when it is unpackaged?

Hardly at all. Even with a 2-inch comfort tier in this 12-inch build, the Tempur-ProAlign 2.0 airs out fast, off-gassing scores 9 out of 10 and resolves in under 12 hours, because it is delivered flat and uncompressed rather than crushed into a roll. Its foams meet CertiPUR-US low-VOC standards. Open it in a ventilated room and the slight new-foam note lifts within a day, leaving nothing noticeable by bedtime.
