This company has the worst customer service I have ever experienced. I have been trying to get a warranty on a mattress i purchased 4 years ago. I have not slept on the mattress for a year because after only 3 years of using it, there were 4-6 in. impressions on both sides of the mattress. After 7 months of waiting for an answer they quoted me a shipping price almost the price of the mattress. I live in Washington and the company is in California. They also said it would be 3 weeks before i got my mattress. So after a year of hassle I have to wait 3 weeks to get a mattress that I will probably have to replace in 3 years anyways. Nobody was ever helpful on the phone and they dragged out the process to get me to give up. I talked to the local company that sold me that mattress and they said they do not do business with them anymore because of their terrible warranty service. I will never be buying a mattress manufactured by this company ever again.
