Hi slumber_lover,
I personally pay little attention to reviews as far as determining the quality or durability of a mattress (as you can see in post #13 here) and much more on the quality of the materials in the mattress. Very few consumers who write reviews know what a good quality material is or what is in the mattress they are reviewing. Of course reviews can give an indication of the type of service provided by a retailer or manufacturer and have some value for this but this also has nothing to do with the quality of a mattress or how long any particular mattress may last. Keep in mind too that all manufacturers make lower and higher quality mattresses. Any mattress that uses lower quality materials won’t last as long as higher quality materials no matter which manufacturers label is on the mattress. In the case of Restonic … they are a licensee group and while most national brands are less responsive to warranty claims and customer service issues than local manufacturers … it would also depend a great deal on which of the licensee factories made the mattress and was dealing with a warranty claim or customer service issue.
I’m looking forward to any ongoing reports you have the chance to provide.
