Will this mattress off-gas when first unboxed?

Barely. Because this 15-inch bed arrives flat-packed in a plastic bag instead of vacuum-rolled, it never traps the concentrated foam odor a compressed mattress unleashes on opening. Its foams hold CertiPUR-US certification, tested against strict low-VOC limits, so emissions stay minimal. Off-gassing rates 9.0 out of 10, with any light scent gone within roughly half a day of ventilation. No fiberglass is used, so setup involves no glass-fiber sock to manage.
