Remove the elastic band that holds the net together. Slowly unfold the mosquito net and place it on the mattress. There is extra net fabric that wraps underneath the mattress for complete seal. Now it is ready to use. There are openings on either side made of high-quality zipper and runner to allow entry and exit. The two pockets inside allow you to hold your mobile phone, AC remote, and spectacles. After use, fold the net using the instructions mentioned on the pack.
