Savannah was awesome 💯 I walked in pretty much knowing what I wanted and she was able to meet my needs immediately. She didn't try to upsell me once. In fact she tried to find me the best deal possible by offering me a discounted box spring. When they didn't have that discounted box spring in stock she gave me a better one for the same price. I was in and out of there in about 20 minutes, and am getting my mattress delivered in only one day. Couldn't be happier and would recommend mattress firm to anyone.

Had a great experience - staff was knowledgeable, and helpful but not “salesy”. We had plenty of questions but they gave us space to roam/shop independently. Once we were ready to buy, it was a seamless experience. Enjoyed our time with Trey helping us!

Robert greeted me with a smile. He assisted me in choosing the perfect bed. He also knew I had an urgent reason for making this purchase and calmed my fears around delivery. Thank you Robert.

Very nice saleswoman. Doesn’t pressure you or follow you around store. Very helpful when I had questions. I walked in and walked out with a purchased mattress in 30 min with her help.

Great service without being too pushy. I really liked the purple mattress. I was excited to come and not only lay on it, but also touch the inside purple gel material. Peter was very helpful and really listened to what we wanted. It also has a little area for kids so they can be entertained for a little bit.
