worst purchase I've ever made

I have had the Sleep Ez mattress for 8 months or so. While Shawn was very helpful and patient and wound up going over and above in efforts to help me make this mattress work, I have not had one good night's rest since I've had it. I have tried literally everything and now I will have to invest another 2k or so for another, most likely memory foam. The various layers I tried in all manner of arrangements offered either support OR pressure point relief, but never both. I now have both more severe pain than I've ever had as well as numbness etc. Before I bought this mattress--after a long day of hiking or house/yard work and my back was aching I could rest in bed or sleep over night and the pain would be gone in the a.m.. Now I can go to bed with a perfectly pain free back after yoga, massage, hot tub or whatever and wake up feeling like I've been hit by a truck. The only reason I got rid of my old mattress was that it didn't work for both me and my boyfriend and I chose a laytex trying to avoid VOCs. I thoroughly regret this purchase and would caution anyone with both back pain and pressure point issues to reconsider a memory foam (there are now a couple manufactured with no VOCs). Just a note: it is 4:30 in the morning--another sleepless night. I would give it zero stars if that was possible.
