Hi ekoprez,
Thanks for the update and feedback … I appreciate it :).
While I don’t pay a lot of attention to reviews (see post #13 here) … I do agree with you about the ethics of editing them without permission and it does call into question the validity of the rest of them.
I also tend to put much less weight on unrealistically long warranties than on the quality of the materials in a mattress purchase (see post #174 here) since they are mostly about marketing and only cover defects in construction and materials (which tend to show up early in the life of a mattress) and not the loss of comfort and support that is the main reason someone would need to replace a mattress.
Their warranty page doesn’t have many details about the specifics so if you can post the details of the warranty here (or attach a picture of the more detailed version) or share your comments about why you were unhappy with it then at least it won’t be edited here
