How long does it take for the mattress to reach its proper size after I take it out of the box?
In order to easily ship your mattress, we compress the mattress and pack it into a box. Once you open the box, your Lull will do most of its expanding in the first 2-5 hours and will fully expand within 24-48 hours. Adjust the cover if it shifted in transit. Any wrinkles will soon disappear.
