The very first thing to do with your new Layla mattress is take it out of the box and get it set up. It will arrive in a box. One person can handle it but two people is ideal. Bring it to you room prior to opening it.
During the unboxing process you will notice a bit of off gassing but it should be very minimal. With most boxed mattresses there will be a little bit of smell once it is allowed to unroll and take shape, but this one is made in the USA which helps with cutting down on any odors.
It should be fine within a few hours but if you are more sensitive to certain smells letting it breath up to 12 hours would probably be a good idea. Also, it is a good idea to allow it to fully expand in the first 24 to 48 hours to get a true feel of the bed too.
Every bed in a box or mattress bought in a store is going to have a “new mattress smell” Even the organic mattresses have a smell. Actually in my opinion a stronger smell since latex has a distinct smell of its own.
Any new smell should dissipate within a day or two.
