It will be much softer and more conforming. The genius is a great mattress but not for a side sleeper or one with the conditions you have. Go spend some time on that mattress before you buy it. There may be a softer one you prefer.

Hi Sherri,

Do you have the chance to try the Savant? If you want it the firmest you can stand, the Savant or Inception are good alternatives to the Genius which can be very difficult to side sleep on. The Savant is a little softer than the Inception. The Prodigy is going to be quite a bit softer than the Genius.

Thanks for choosing iComfort. The Genius is the firmest of our iComfort models and while many people who like firm mattresses are happy with this model, it can be too firm for side sleepers based on what we’ve heard from our consumers. It can take several nights to adjust to a new mattress, and since it’s only been two nights, you may need longer to adjust. Even so, we want you to be happy with your mattress. We use a comfort scale ranking at Serta from 1-10, with 1 firmest and 10 softest. We rank the Genius at a 3 and the Inception at a 4, so the Inception is just slightly softer.

For the rest of the models: Genius - 3, Prodigy - 5, Insight - 5, Reinvention - 5, Acumen - 6, Renewal Refined - 7, Savant - 7, Epic - 8, Wellbeing Refined - 9

Thanks!

I bought the Pietra series at Sams club, like the first person I also have fibromyalgia. The sample in the store that you could pull out and lay on was much softer than the actual mattress that I have. I really don't get any benefit from the cooling gel infused....it is still hot. I toss and turn a lot and the mattress shifts and one side will be hanging off the side two or three inches and there will be a gap big enough for my pillows to fall through by nights end. I was really sore for about 2 weeks. My old mattress was moved to an upstairs bedroom and I have been tossing around going up and sleeping on it for a night to see if it was just that good. As far as the Pietrra goes, I would say if you are a back sleeper with no health problems, it may be a good choice for you.
