Mountains and Canyons

Purchased this mattress at Sears after reading many reviews and intensive research. Initially happy with comfort, support and overall rest. After 6 months, noticeably started to wear with indents happening. Contacted store, they stated this was normal for pillow top mattresses. After 1 year, indents turned into troughs. Contacted store, they referred me to the mfg. contacted mfg, they sent me to warranty (3rd party). Multiple calls, messages left, emails sent, I finally spoke to a human and I was provided with a litany of items in which I had to provide. After measuring with strings and rulers to gather the appropriate photos in the specific areas of concern, I packaged all documented evidence and forwarded to appropriate parties....and waited. After 1 week, called to confirm my information was received...they had NO RECORD of my ticket or information of the data I sent. I opened another ticket, took names of those I spoke with and, again, sent daya. 1 week....I cannot reach a human to confirm receipt of information. Complained to Sears, called, emailed, to no avail. Tired and dismayed, I gave up. Today marks 5 years where troughs have evolved into grand canyons and a mountainous devise causing a multitude of sleep issues. I’m shopping for a new mattress armed with a “buyer beware “ attitude regarding warranty and durability/longevity expectations.
