Will this mattress smell when it is new?

Very little. Its comfort foams are CertiPUR-US certified and tested against strict low-VOC limits, and it is made in Canada and delivered flat in its bag rather than vacuum-compressed in a box for weeks, scoring 9.0 out of 10 for off-gassing. There is little to release in the first place. Off-gassing clears in under 12 hours, so air the room out briefly after unwrapping and any faint scent dissipates.
