I had lower back issues for years. After purchasing and sleeping in my split king ghostbed for a week or so, my back issues definitely improved. My wife and I really enjoy our ghostbed and would definitely recommend it to anyone.
The screws that screw in to the bedframe were visibly crooked. Thus, screwing them into the frame, the legs were wobbly. Contacted the company with pictures, who stated nothing was wrong with the legs and refused to do anything about them. Very poor workmanship. See picture showing the screws are not straight. When you pay the price you pay for this bed, I expect a good quality product. Buyer beware!
