I love the firmness of the mattress and the softness of the pillow-top balances it all out. I have had reoccurring backaches for months and since we purchased the new Serta Perfect Sleeper Hillsgate II I have had the best sleep. I use to wake up after a couple of hours needing to turn, stretch, and at times swap to the foot of my old bed just to get any relief for my back. I am now sleeping through the night and have already noticed I am not tired and drained in the morning. Thanks Serta for this great product at such a great value for the price.
