Using this mattress is a breeze. Once you receive it, simply unpack the box and place the mattress on your bed frame. Make sure your bed frame has a foundation or slatted supports as the mattress fits best on these. It will start to expand right away, but give it 48 to 72 hours to fully reach its intended size. As for sleep, no matter if you're a back, side, or stomach sleeper, this mattress is designed to support you. When it comes to maintenance, keep the mattress clean by using a mattress protector. You can vacuum it occasionally to remove dust. Avoid spilling liquids on it, but if you do, clean it up immediately with a soft cloth. Also, try to rotate the mattress every few months to ensure even wear and tear.
