We have designed Nosda with our customers’ best interests in mind, including ensuring that the mattress is easy to set up. To help you with the setup process, please follow these steps: Place the box in the room where you intend to use the mattress. Carefully remove the tape from the top of the box and lay it on the floor. Gently pull the mattress out of its plastic casing and position it on the headboard of your bed-frame. While the mattress is still in the plastic, unroll it towards the foot of the bed. Remove the plastic that secures the mattress, ensuring that you discard it properly. Allow the mattress to expand and reach its actual size for approximately 30-60 seconds. Please note that full calibration typically takes 2-3 days, but you can start using the mattress for sleep as soon as it becomes fully inflated.
