I have now had my Ghost Bed for almost 2 months now, and I am very pleased with it. I am a heavier person and it does a great job supporting me, does not sink in, and it is comfortable even for a side sleeper. I just recently recommended Ghost Bed to my brother and he is already a fan as well.
A bit more firm then I anticipated but haven't woke with any aches or pains thus far. I like the edge support how it doesn't cave in like some other mattresses. No regret.
