Zenbivy Light Mattress Owner's Manual

Inflating your Light Mattress the first time:

The Light Mattress uses our Inflation Dry Sack to aid with inflation. This allows for quicker inflation times and also keeps moisture out of your mattress. 

Storing your Light Mattress:

The Light Mattress can be stored rolled up and inside its Inflation Dry Sack. The insulation we use spreads upon inflation to insulate, so your mattress does not need to be stored loosely folded or laid out. Check that your mattress is clean and dry before it's stored. 

To inflate:

1. Make sure the valve is facing the correct direction to allow air to flow into the mattress. The red tab on the reversible valve should be flipped so the "inflate" side is facing outward. You will have the green center button facing out (the large, circular part of the green valve will be inside the mattress).
2. Couple the Inflation Dry Sack with the valve on the mattress.


3. Open the Inflation Dry Sack and hold it into the wind to fill with air. If there is no wind, you can blow gently into the top of the sack to fill it. Roll the Inflation Sack from the top to squeeze the air into the mattress. Repeat until the mattress is firm, then remove the Inflation Sack from the valve. 

4. Unsnap the Inflation Dry Sack from the valve. Lay on the mattress on your side, push the green valve to slowly deflate until your hip just bottoms out, so you are using the full depth of the mattress.  This is a great starting position to determine how firm or soft the mattress should be to work best for you.  Note that most people tend to run the mattress too firm.  Softer is generally more comfortable even if you sleep on a firm mattress at home.  Experiment to determine what works best for you.

5. Secure the valve with the outer cap.  Note if you want to adjust the pressure after the outer cap is attached, you will need to hold the valve in place when removing the cap to avoid pulling the valve completely out.

To deflate:

1. Pull the valve completely out.

2. Without folding, loosely roll the mattress starting from the end and push out as much air as possible. Insert the valve with the large round circular part of the valve on the outside, this is the "deflation" valve side and it is designed to keep the air out as you roll. Unroll and fold the mattress into thirds, then roll the mattress into a compact storage roll.  Once all air is out, secure the valve with the outer cap.
3. Place in storage sack and start planning your next adventure!
Size Chart

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm. If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally. When in doubt, size up.
