Core Bed Owner's Manual

Attach the sheet to your mattress

First thing's first! The Core Sheet needs to attach around a mattress, whether it’s one of our mattresses or your existing sleeping pad.

Step 1: Attach the corners of the fitted sheet around an inflated mattress.

Step 2: Clip and adjust the strap on the underside to keep it securely in place.

Step 3: Inflate your camp pillow and pop it inside the sheet's integrated hood. 

Footbox Options

Now that your sheet is on your mattress, we’ll move on to the quilt. The Core Quilt's Fast Footbox™ offers 2 setup modes — "Mummy mode" for maximum warmth and "wide mode" for maximum space.

Option 1: Mummy Mode

To form mummy mode, flip your quilt over so the lining is facing up. There's only one clip down there—clip that! There you have it. Mummy mode!

Option 2: Wide Mode

If you want more leg room, you can open up mummy mode into what we call “wide mode”. This mode provides a wider footbox while still maintaining warmth. To form wide mode on the Core Quilt, simply unclip the only clip down near the footbox. Done!

Attaching the quilt to the sheet

By attaching the quilt to the hinged “wings” of the fitted sheet, you’re blocking drafts and also keeping the quilt from sliding off you throughout the night. Attaching one side is great for side sleepers and attaching both sides is ideal when it’s cold out to block any side drafts. However, you don’t have to attach the quilt at all if you don’t want to! Test it out and see what works best for you and your sleep style.

If you want to attach the quilt to the sheet, locate the 4 color-coded loops on either side of the quilt’s exterior and match those up with the 4 loops on each side of the sheet. 

Cinching the Kylie-curve™ 

When needed on cold nights, you can cinch the drawstring that runs along the top center portion of the quilt. This helps to seal in warmth around your neck and prevent any drafts.

To cinch the Kylie-curve™, squeeze the cord lock and pull on the loose end to create the curve in the center. The shorter tunnel on the corner of the quilt is just to help guide the excess cord out to the side of the quilt.

NOTE: You do not need to cinch it much. A small amount of cord will create the “hook”. If you cinch it all the way, it’s only going to shorten the top edge of the quilt. You want to cinch it just enough to “hook” around your shoulders/neck. Play around with it and find what’s comfortable for you.

To undo the curve, simply squeeze the cord lock and pull on the sewn-in end to straighten the top edge of the quilt again.

Long term storage

When storing your Bed, it's important to give it space. To protect the longevity of the insulation, you never want to store it long-term fully compressed. Each Bed comes with a large mesh storage bag. When coming back from a trip, we'd recommend pulling your Zenbivy out of its Dry Sack as soon as you get home. If it's a nice sunny day, you can hang it up outside for a bit to air it out and let any moisture completely evaporate before stuffing it loosely into the mesh bag.

Each of the down chambers is fully baffled and separated from other baffled chambers, so down can’t migrate and never needs to be “redistributed”. Simply shake the quilt out and let it sit in a warm room and it will regain its loft even after being semi-compressed for a very long time.
