Received Prodigy on 1/28/12. Loved it for the first 9 weeks. Then out of blue started having mid to lower back stiffness. I only way 205lbs. Place I bought from only offers exchange for equal or greater value, within 90 days. Doesn't honor 120 day trial Serta declares on their web site, nor do they honor Serta's refund policy if not satisfied. I am going to contact Serta to see if they honor the policy on their own wed site but don't have high hopes since have statement their vendors can have different policy(written in lighter text so as not to notice). I can upgrade to Renewal but very leery to spend more money on a bed that could end up with same problems in another 9 weeks.

My wife and I just received the iComfort Genius we bought about a week ago. We spent about 6 hours total testing the various models of iComforts as well as some other beds before deciding on the Genius model. We went with the firmer Genius as I prefer a firmer mattress and my wife can sleep on just about anything without any issues. The other model we were close to was the Revolution but went with the Genius after reading posts about possible break down in firmness over time. So here are my first thougths after the first night on the bed.

** Smell - our bed did have the odor from the foam but it was what I expected from my experience with memory foam toppers we have bought in the past. I wouldn't say it was overpowering and it didn't seem to bother my wife or I during our first night on the bed but it is definitely there. Expect that to dissapate over short period of time.

**Temperature - using 250 thread count sheets, I did not find the bed hotter than a normal spring mattress but I wouldn't say it was any cooler either. I have read on other sites that if you are getting hot at night during sleep, consider changing to a lower thread count sheet as the higher thread count sheets do not breath as well and therefore you will sweat more. Didn't wake up sweating during the night so I dont think temperature will be an issue with the mattress.

**Comfort - on the innerspring mattress we just moved from, I was awaking constantly during the night (6-10 times a night). First night on the iComfort was pretty good. My wife said she doesn't think she moved all nigth and slept on her side which she said caused her down side shoulder to be sore this morning. I did awake about three times last night but I definitely slept better than I was previously. I have some lower back issues and my back was still sore this morning but I think I will need to give it some time to see how my body adjusts. We also moved from a queen to king size so it was nice not bumping into each other during the night.

**Overall - first night was pretty good, definitley different than the spring mattress we had been on. I will say that when I first get on the bed, it seems very firm and then once you lay there for a bit, the support I got was very good and comfortable. Time will tell.

**Durability - too early to tell. WIll update in a couple weeks with where things are at with our overall experience.

I have been waking up every morning with back pain for a long time due to my 19 y/o mattress.

I just got an Icomfort insight mattress, the reason I chose this was because I didn't want a really soft foam mattress, and it was in my price range around $1200.

This thing is amazing!!! No more back pain !!!!

The mattress is still very new so I will post again later. But so far so good. Zzzzzzzzzzzz
