Hi Jerxa,
I would first make sure that you have the specific information you need about the Bob-O-Pedic to make an informed choice (specifically the thickness and density of all the layers). In my experience they are not particularly knowledgeable or transparent about their mattresses (see post #4 here) and I would make sure that they fit the memory foam guidelines in post #10 here (including CertiPur certification).
Dreamfoam of course is a member here which means I think very highly of them. They are open and transparent about the materials they use and are CertiPur certified and are among the best quality and value available although of course besides just quality and value your own confidence that a mattress matches your needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) is also an important part of any mattress choice.
I’m not familiar with the Bob-O-Pedic power base, its features, or who makes it but the adjustable bed thread here has some good information and has links to some of the sources that I use for “value comparisons”.
