Using your new hybrid mattress is a breeze. First, unpack the mattress from the box and place it on your desired bed frame. It'll start to expand right away, but give it 48 - 72 hours to fully expand. You don't need to do any assembly - just lay it down and you're good to go. When it comes to maintenance, regularly rotate the mattress every few months to ensure even wear. You can spot - clean the knitted fabric cover if it gets dirty. Avoid using harsh chemicals on the cover or the foam. For long - term use, keep the mattress in a dry and well - ventilated area. If you're using it in an RV, make sure to secure it properly to prevent movement during travel. Enjoy your restful nights on this comfortable mattress!
