Upon receiving your brand new Shin-Ju II mattress, find a clean and dry place to start unpacking. The unpacking area should be about the size of the mattress ordered. We recommend doing it as near to the destination bed as possible for maximum convenience.
Start unpacking by carefully using a pair of scissors to cut open one of the small sides of the box. Resting the corner of the open side on the ground, tilt the box upwards into an upright position (with the cut-open side facing down) to easily remove the mattress by lifting the box upwards and off.
The first step to giving your mattress "life" starts here. Be extremely careful when cutting the protective plastic sheet open. Please follow the colored-cutting line on the packaging and don't rush. It's best to use a pair of scissors, as penknives can easily slash your new mattress.
This is the most fun part. The moment you cut open the protective plastic sheet, air will rush in and you get to watch as the mattress "grow" to its full size. Continue to let the mattress "grow" for a further 2-3 minutes before fully removing the entire protective plastic sheet layer. Resist the urge to lie down at this point!
Once inflated, place the mattress onto your bed frame. We recommend getting someone to help with the other side for Queen Size and above. You can sleep on the mattress immediately, but it will take a further 2-3 days for the mattress to fully inflate and expand. You may experience a softer feel during the 1st few days but the mattress will gradually get firmer after time.
