Using your new mattress is super easy. First, find a suitable bed frame that has a foundation or slatted supports. Then, unpack the box and place the mattress on the frame. Remember, it's compressed, so give it 48 to 72 hours to fully expand. You can sleep on it in any position you like - back, side, or stomach. To keep it in good shape, vacuum it regularly to remove dust. If there's a spill, clean it up right away with a mild detergent and a soft cloth. Also, try to rotate the mattress every few months to ensure even wear. And always make sure the room has good air circulation to keep the CertiPUR - US certified foam working well and maintaining good indoor air quality.
