backache everyday

This is the 2nd Serta Mattress we have purchased, The first was a pillowtop that lasted only 6 years (started having problems after the 3rd year) took us time to save up for the next mattress. The 2nd Serta Mattress was icomfort insight purchased in 2011. We both liked the mattresss the first year. The second year we noticed that backaches started to return, kept turning it to no avail, turned the foundation also, no relief there either. Now we can hardly move in the morning because of backaches from sleeping on this bed. This is the second serta mattress purchased at American Mattress and will never purchase another Serta product or never purchase from American Mattress again. I visited American Mattresss this morning and talked to their rep, he sad they can send out an inspector to inspect for $120.00, I think NOT. The warranty is still in effect for this mattress but without shelling out another $120.00 to have an inspection they wont do anything for us. NEVER, NEVER NEVER AGAIN purchase Serta.
