So you've ordered your new mattress, it's been delivered with zero issues and you are just about to do the new mattress comfort test (lying down for ten minutes and trying not to fall asleep) and you notice your mattress is omitting a smell. This is totally normal, common in fact especially if you have ordered a mattress online and it's come in a box. It's a phenomenon known in the mattress world as off-gassing.
Off-gassing is most common in mattresses that are vacuum-sealed and packaged quickly after production, with some materials being more prone to it than others. But Even the best mattresses on the market can emit an odor, which can be off-putting or even interrupt sleep if you’re particularly sensitive.
