Setup Instructions
Your Serta mattress is conveniently packaged in a box for easy delivery and setup. Follow these steps to prepare your mattress for use:
- Unpack: Carefully lift the box to the desired bedroom and remove the mattress from the box.
- Unroll: Unroll the compressed mattress onto your bed frame or foundation. Carefully remove the plastic and/or paper wrapping. Do not use a sharp knife or scissors to open the plastic wrap as you can risk damaging the mattress fabric.
- Unwind: Allow the mattress to expand fully. It can take 24-72 hours for your mattress to reach its full size and comfort level.

Maintenance
Proper care will extend the life of your Serta mattress:
- Cleaning: Spot clean only. Do not apply liquids directly to the mattress. For spills, use baking soda to absorb moisture and odors, then vacuum after 15 minutes.
- Protection: Utilizing a mattress protector is highly recommended to safeguard against spills and stains.
- Cover: Do not remove the mattress cover.
Troubleshooting
- New Mattress Odor: It is normal for a new mattress to have a slight odor upon unpacking. This is due to the fresh materials and will dissipate as the mattress airs out. Allow one week of use for the mattress to fully air out.
- Incomplete Expansion: If your mattress does not appear to have fully expanded after 24-72 hours, ensure it is placed on a flat surface in a well-ventilated room. Continued use will help it reach its maximum comfort.
