I spent my first night in a hammock last night in a Ultralight Explorer with side zip. I could never get comfortable. I'm 5-11 weigh 165lbs. I have some questions, please.

1. I could never get "level". My butt was always sunk lower than my head and feet. I did lay diagonally. The bottom center was always pulled "taught" which created a sort of ridge under my butt.

2. I had the sides staked out but they still crept in on me. How and taught should they be staked.

3. I kept sliding down from my head.

4. There is a little velco tab on the outside seam of the hammock. What are these for?

5. Any suggestions please.
