Your sleep habits should help define your final decision. Side sleepers tend to like the softer mattresses. If you are a side sleeper, factor in this. If you experience back/lumbar discomfort, go with the Plush mattress as it will be more supportive. If you are a experiencing sore hips, sore shoulders, joints, or wake up achy, then the pillow top will help improve the way you feel.

If you do not sleep on your side or are not always on your side, go with the Plush.

It is important you lay on them in the position(s) you tend to sleep in. It is true, if you are side sleeper you may enjoy the softer of the two. Spend 15 minutes on each one to be sure, and don't forget to shop local.

I wouldn't buy either one. The entire iSeries line has been revamped and the new line is a better value. Look at the Merit - Super Pillow Top in the new line up. And, I agree, whichever one you choose, buy it locally!
