We bought before trial and was nervous. Thankfully it was a great choice, I would recommend the product and advise to take the quiz to help find the perfect match for your sleep.
Finally had enough of the mattress in the RV and got a Ghostbed. Only bad thing was I had it the wrong way when taking the shrink wrap off. The mattress started sucking air before I had it oriented or skinned and I wasnt quick enough. Once it was in the right way I didnt use it for a while, then went out for 3 nights. There was no waking up and my back didnt hurt from the bed. Wife hasnt accompanied me yet so the official verdict has not been handed down, but I think she will be OK.
I've tried a range of mattresses, from expensive to budget-friendly. So far, this is the best I've found; there have been no issues. I highly recommend it.
