A special 3-in-1 storage bag is included with the air mattress. You can use the bag as a storage bag to store the air mattress in and as a travel bag to easily take it anywhere. Additionally, you can inflate the bag with air and use it as a pillow when sleeping or to rest on. By filling the bag with air, you can also use it as an air pump to inflate your air mattress. Fill the bag with air and then attach it to the valve of the air mattress. This way, you can easily fill it with air. Thanks to this unique technique, you only need about 50 seconds and about 6 hand compressions to fully inflate the air mattress. If you don’t want to inflate the air mattress with the supplied air pump, you can also do this with a foot pump (not included) or an electric pump (not included) thanks to the double valve.
