Will there be an off-gassing smell when it arrives?

Very little. Any new-mattress scent clears in under 12 hours, faster than most beds, because this mattress ships flat-packed rather than vacuum-rolled, so far less is trapped inside to release. It is built on CertiPUR-US certified foams tested for low emissions and assembled in Ontario. Unwrap it, let it breathe in a ventilated room, and the faint scent airs out within the day.
