From GREAT to HORRIBLE

We bought the new Revolution Icomfort by Serta from Mattress Firm January 2012 on the recommendation of the salesman (Joseph Sabino). He told us that after the break-in period that we would find the mattress would contour to our body and give us the support we're looking for. In the beginning the mattress was firm and as it broke in became very comfortable - at first. The mattress continued to breakdown, sag to the point that I now sleep in a hole. My back hurts terrible when in the mornings. Considering that I had back surgery and need support, I am extremely disappointed in the quality of the material. I have not had a good night's sleep in months and being that I am warm nature and though salesman told us the material in the mattress was design for folks like me, not true. I find myself sleeping on top of the sheets as I am burning up. I definitely cannot recommend this mattress for folks like me that require support and cool environment for quality sleep. Not to mention the manufacturer's warranty does not do justice for internal sagging. As the mattress returns to form but, it does not hold its' form. Tells me the manufacturer uses substandard materials to not stand behind their quality. Most assuredly is frustrating to have spent $1,700 for a mattress that 17 months later we need to replace. Would not purchase another mattress from Serta. If sales people at Mattress Firm are aware of this issue and do not advise their clients, shame on them and should be boycotted.
