Move mattress to the room where you plan to use it. Remove mattress from box.
Lay mattress on its side on top of bed foundation. Locate the seam in the plastic—it runs from one end to the other.
Notice the flat spot/void under the seam where the mattress end rolls into itself. Using the included letter opener, carefully cut along the seam. Take care that the blade does not come in direct contact with mattress. Remove and discard the outer plastic wrapping.
Allow mattress to unroll and unfold on the foundation. Again, using the included letter opener, carefully remove the inner plastic bag. Take care that the blade does not come in direct contact with mattress. Mattress will immediately begin to expand.
Your mattress will be ready within a few minutes, but it may require between 24 to 72 hours for it to fully regain its shape.
