Kane's Furniture HUGE DISAPPOINTMENT when they refused to stand behind $900 Sealy Posturepedic mattress they sold me. Ocoee Florida

What a disappointment when my 4-month-old, $950 Sealy Posturepedic mattress developed a "hollow" where I slept!  (I weigh 148 pounds, and was the only user of the bed.)  I turned it and within a few months, had another hollow spot.  This was repeated twice more--and I was sleeping in the middle to avoid the depressions.  

When I went back into the store, they gave me the run-around.  I went in again to complain, and they said they would send someone out to look at it--and MEASURE the depth of the depressions!  Not long after, a man arrived with a piece of string which he laid across the bed, announcing the low spots were  not deep enough.  I even tried to get him to lie on it, but of course he refused.  

My son has given me an old mattress he had (He paid $500 for it) and I'm sleeping okay, but it's not at all what I was hoping for!  I went in one last time, and the manager argued with me and refused to do anything about it.  I'm about to purchase a solid natural foam mattress, but you can imagine, I'm really disgusted with Kane's.
