After 12 years using a Sleep Number bed that has failed us the last two years without real recourse except to buy a new one at an exorbitant price, we decided to go back to a traditional mattress with an adjustable split top. The President's Day sale was well worth it and we were able to purchase a king size mattress with an adjustable power base at Mattress Firm in Flemington for a very reasonable price. This is actually our third or fourth mattress purchased at this location over the years. They have a ton of selections and the salesman, Charles, was very well versed in the products and brands without being pushy. We can't wait to receive everything.
View on GoogleWe had a fantastic experience at the Flemington mattress firm. Charles was so helpful throughout multiple visits and much deliberation. He was extremely patient, informative, and thoughtful in helping us choose the best mattress for us. Highly recommend, thanks Charles!
View on GoogleCharles Thompson was my sales associate. Very professional, yet personable. No pressure. Purchased on Monday - delivered 2 days later! Super helpful when I needed to make a last minute change to my order. Delivery guys (Raul and ?) were terrific. Very careful negotiating the narrow hallway and door way. Overall an unexpectedly positive experience from minute I walked through the door through deliver and setup. Highly recommend Mattress Firm (Flemington).
View on GoogleBrandon did an awesome job showing us a variety of mattresses without it feeling overwhelming. Very knowledgeable about each one concisely explaining the differences. Never felt pressured into buying anything but came out with a mattress after a couple hours. Thank for your help!
View on GoogleWe had a great experience at Mattress Firm. We checked reviews online and all of the positive comments were true for us as well. Our sales agent, Charles, took time to get to know what we were looking for and answered all of our questions about the different mattresses. We decided to shop around a bit and concluded that working with Charles was better than any other option. Of course the test will be our happiness with the mattresses themselves but we know that Charles will be there to help us if we have any issues or concerns.
