I have spent the first week in your bed...it is awesome. I no longer awake with joint stiffness, I can sleep on my back because I can have my legs elevated which reduces suffering from "restless leg syndrome," and my dogs can sleep next to me in total luxury!! They don't even mind sleeping in the "crack!" It really is comfortable, Yong. Thanks for all your help. If I had beds that had more use, I would buy more. Think I will get one for my daughter when she gets her first apartment after college next year!
