Absolutely LOVE this bed, my wife and I have now purchased 3 of them!
The Serta iComfort Prodigy is the best bed I have ever owned. We purchased our first one right after they came out. I had back problems and we needed a new bed so we spent hours laying on the bed in the store and finally settled on it. My wife to this day still says its the best decision I ever made. About 2 years later we decided we wanted to move that mattress to our spare master bedroom for our guests, so we bought a new split king with the adjustable base. I loved it, but my wife was not a fan of the split king and our young sons are about the age where they will need a real bed, so we split the bed in to the two twins for their rooms and purchased a new king iComfort Prodigy III. Our third version of this mattress and we have loved every single one of them (obviously if we bought 3 of them right?). You can't go wrong with this mattress, I am sure you will not regret it if you purchase one.
