Hi Dave-
My wife and I were extremely excited for our California King Icomfort Insight. When it arrived, we were taken aback by the extremely strong smell. Being that we live close by to you near Crystal Lake, Illinois, it was cold when the mattress was delivered on April 1st. The first 2-3 nights, it was unbearable to even enter the room due to the intense smell expelled from this mattress. We opened the windows completely even though it was 40 degrees outside, turned the bedroom ceiling fan on high, and had a space heater going in the room to at least keep it a little warmer. We did this for about 60 straight hours before finally being able to sleep in our new bed.
We let the bed air out before placing our Protect A Bed mattress protector over it. The smell was still present in moderate strength for the first 10 days then it became less noticeable. Our dog who sleeps with us in our room every night, would not enter our bedroom to sleep with us for 7 days due to the smell.
So once we were able to sleep on it, both my wife and I suffered from neck and lower back/hip soreness for the next 4-5 days(I am 29 she is 27 and we were both Collegiate athletes in great shape with no aches). On about the 6th day it finally was starting to feel comfortable for the next 2.5 weeks. Now at about the 3 week mark of having this mattress, the spot where I sleep already feels as though it has lost its firmness. Right where my buttocks hits the mattress, it now sinks straight in and doesnt provide ample support of my body. I am 6'6 240lbs in case you are wondering. So when I lay in the bed now, it feels as though my legs are elevated, it feels like my butt sinks way too far in and it feels like my head is way too high up even with a flat pillow or the memory foam pillow. It is giving me the hammock feeling you are describing.
Upon going back to our store, we were told that it may of been a manufacturing defect, and in all honesty, it may be. Nonetheless my wife and I decided that with the lack of feedback/reviews on this line and the bad experience we had, it would be wiser to try a more traditional mattress. We were afraid that if this could occur at 30 days with the memory foam losing its support, that what would it be like in 1-3 years. Also as you should also know, sleep innovations does provide an almost identical memory foam mattress at costco under the brand Novaform for less than 50% of the cost.
If you want a king Icomfort, you can just do this, here is the Icomfort line for less. The king size Icomfort Insight is ONLY 8 inches and will cost you 1299.99 for the mattress alone. The Icomfort line is overpriced for the quality of the mattress especially when compared to the same manufacturers line at another place with the same technology and thicker mattresses. Just my .02
Gel infused 12inch memory foam King Size 799.99
