I purchased a mattress here. I told the associate that I knew nothing about mattresses and needed help finding one. We looked around and found a mattress and he told me several times that if the mattress didn't work out I could exchange it without problems within 30 days. I came back to exchange it because it was giving me back problems and making me wake up in sweats and they told me they don't take back mattresses. I spoke to the manager and I told him my situation and he did nothing to solve the problem and is charging me a "preference" fee. All he could say was he was going to speak to his associate about the wrong information he told me. The sales associate blatantly lied to me and left out important information just so he could sell me this mattress and they were unwilling to do anything about this.
