I went into the Denver Mattress Store because I had seen it online and liked that they had their own non-toxic mattress line that they manufacture their own line in Denver, Colorado. However, I gave up on considering an online store purchase because I wanted to try out the mattress in person before I purchased it and also due the potential expense and difficulty of exchanging, shipping etc., of a mattress and frame. I actually was in the Draper, Utah, area to go to another furniture store when I saw the Denver Mattress store sign and was thrilled to check it out as I did not know Denver Mattress had a store in Utah. Anyway, I was not comfortable with one of my options of buying a 100% pure nontoxic latex mattress on the chance that I might be allergic to latex because I am very allergic to avocados which is a cross-linked allergen to the rubber plant from which latex is made. I am also sensitive to wool. So I am also wary of purchasing a mattress using wool as the flame retardant material. I was surprised at Denver Mattress' quality, use of non-toxic materials, great price with the sale, the trial period for exchanges, and their warranties on the mattress and the adjustable frame. I was equally impressed by the no-pressure approach, knowledge, honesty, patience, and sense of humor of Aaron Ellis who helped me on the showroom floor. Since I had done months of research on mattresses and adjustable frames, I am extremely knowledgeable about matttress construction, legitimate certifications, TB117-2013 requirements for flame retardance chemicals and the history of those chemicals for mattresses going back to 2007. I was so impressed that Aaron was totally knowledgeable about history of flame retardants and mattresses and was willing to listen to all my concerns and my list of desired features in a mattress and adjustable bed frame. Aaron also has a wealth of knowledge about so many mattresses, frames, and the manufacturers. I am most grateful to Aaron for his expertise, efficiency, professional manner, patience, and sense of humor. After speaking in length with Aaron, trying the mattresses and adjustable frames in the store, and reading the "To Whom It May Concern" November 7, 2011 letter from Denver Mattress' General Manager, Robert Rensink, stating that " At Denver Mattress we do NOT use any chemicals in any chemicals in assembly of our beds," I purchased three non-chemically treated flame retardant mattresses: two twin XL Doctor's Choice Elite Plus and one Doctor's Choice Elite Firm twin CL mattresses with three of the model Rejuven8-2 adjustable twin frames for my family. I really like that these mattresses have pocketed coils, nontoxic materials, a great luxury feel, and work with an adjustable frame! I was equally impressed with the Denver Mattress's adjustable frame including the very nice leather-like finish, the leg extension kits, the bolted headboard attachment kit, the options mattress protector and pillow package (which I did not purchase as I had my own already), the 2 USB ports on each frame, and the massage, head and foot adjustments, and wireless controls features! I intend to write a follow-up review of my experience with the new mattresses and frames. Until then, my heartfelt and BIG THANK YOUs to AaronEllis and Denver Mattress of Furniture Row!
