Another L 4&5 sufferer, with sciatica and some nerve damage. 9 nights on the ground in the Grand Canyon drove me up in the air. I have slept well ever since in a BB and also a Switchback when I can get it away from my wife. One of the biggest benefits to me has been the getting up part in the morning. Stepping out of a hammock and slipping into the camp shoes vs crawling out of a tent.
