- Carefully slide compressed mattress out of box.

- NOTE: Depending on the mattress you’ve received, you may need to unfold the compressed mattress after unrolling it, or you may just need to unroll it before removing final layer of plastic. Please take a moment to consider that before proceeding to the next step.
- Unroll and unfold (or just unroll) the mattress and position it on your base. Carefully cut and remove final layer of sealed plastic from the mattress.
- Carefully discard all packaging materials immediately after removal to avoid any hazard. Keep all packaging away from children.
- Allow your mattress to decompress naturally for the first 24–48 hours. Once it is fully expanded, manipulate the corners and sides to square it off as best as possible.
