Bests & Worsts Reviews from Amazon

I initially loved this mattress, however, 5 months in, it started having a crack that would sink 4-5 inches when laid on, 2-3 without any pressure. Simmons claims warranty is invalid because bed slats are 1/2 inch too wide apart (though it is a standard, mass-available bed frame). They are the only company I found with this requirement and millions of people own the same bed frame as me--this is just poorly made and defective. This mattress is poor quality, and Simmons is a disgusting company that will do anything to get out of paying for a defect. Clearly the springs just separated or glue didn't hold or whatever, yet they won't fess up to their mistake. Customer service was rude and condescending. DO NOT BUY.
