Maybe this is cheating a bit, since I don't know where to tell you to buy a hammock like this.  Mine is one of two that my parents brought back from backpacking in South America shortly before I was born.  They slept in them, with the addition of mosquito nets, on boats on the Amazon, in rented rooms with hammock hooks instead of beds, and wherever else they could find to hang them.  Then they came back to the US, and I was born.  This hammock made a bed for me when I needed naps, a quiet place to play or read in the shade when I was older, and an all-purpose lounging spot.  And now, nearly 30 years later, it goes camping with us.

Whenever the hammock comes out, Caiti immediately climbs in and goes to sleep!
