Almost 2.5 years fulltimeing and no problems whatsoever. I do sleep on the diagonal but on the back or left side and recently even on the right some. Spent a few nights this summer both going to and coming from Maine in an RV. High dollar memory foam mattress and I was almost crippled every morning. Spent 2 .5 months in the hammock behind the RV thru the summer and all was well. Unfortunately there are a number of hammock hangers out there that haven't found the Forum and the wealth of information here.
Most of us end up poorer here but richer for being here. Olddog, Fulltime hammocker, 365 nights a year.
