The hammock has 4 positions:
1 fully vertical, 2 recline positions and 1 flat (for storage).
There is a tab at the head of the seat. This is the inclination and recline adjuster, you should pull the tab up and push the seat forward to raise the hammock. To recline it, pull the tab and push the seat down until you reach the desired position.
You can use the hammock both statically and in motion.
There are two curved profiles on the outside of the flat black base so the Swing & Flat hammock can swing. These are pulled down and placed under the structure.
