I stopped ranking beds a few years back. There are just far too many brands, and frankly, I don’t have the time to chase down and test every single model or variation. I do however want to send a shout out to the 2017 iComfort® line from Serta®. Here is what I said about them in 2012

Serta® – The iComfort® line did exactly what they needed it to do, bite into the market share of Tempur-Pedic. The Revolution (now called Savant) felt similar to Temp’s Cloud Supreme and was sold for $700 less, even after the Supreme’s price reduction. From the Prodigy on down, and especially at the Insight and Genius level, they are a solid value for the money. And I must say, they are the best looking memory foam collection of the top brands. They are the most serious threat to Tempur-Pedic dominance in the category. The “cool” gel theme has been effective at creating doubt in consumer’s minds.
