Place the compressed mattress topper on top of your mattress. Carefully cut open and remove the outer sleeve with scissors.
Gently unroll and unfold your mattress topper onto your bed. Remove the protective fabric liner. If your mattress topper comes with the cover detached, place the cover on the mattress, then place the topper in the cover (blue side on the bottom), center, and zip.
Your mattress topper will expand immediately and start to regain its natural shape. It may take up to 24 hours for your mattress topper to fully expand.
