I'm very satisfied with this seat post. My 1.5 years old daughter is too large for the hammock. But in the big seat she has not too good grip. She slips slightly back and forth. With this support it is secure. While tilting your head while sleeping often still ahead, but at least not to the side. Of course, the rest is overpriced. But there are, unfortunately, as far as I've seen, no real alternatives.
