We had a wonderful experience at Mattress Firm yesterday thanks to Kevin and Sunny! They were both incredibly friendly, patient, and accommodating to our situation from start to finish. They took the time to answer all of our questions and made the entire process smooth and stress-free. Customer service like this is hard to find these days, and we truly appreciated their professionalism and kindness. I would highly recommend this location to anyone looking for their next mattress!

The shop was clean, well lit and user friendly display of product. Our sales rep was friendly, warm and very knowledgeable. Sonny took his time to explained various products. He was very patient, answered all questions in an easy to understand manner. Mattress Firm is my neighborhood store and I will highly recommend my friends and neighbors to shop there and ask for Sonny.

Sonny is really helpful, he is definitely the most professional mattress salesman I’ve ever seen. He’s patient, knowledgeable friendly and helpful to demonstrate and illustrate your wants and needs, demonstrating the differences for your understanding, strongly recommended from the bottom of my heart!!

The staff here are so friendly and knowledgeable. My brother and I were lucky that the mattress model we wanted was the last one they had in store. I believe the staff member helping us was named Sonny (sorry if I spelled your name wrong), and he was also training another staff member. Both were patient to my brother and I as customers and I always find it a green flag when supervisors are respectful to junior employees /staff in training. Since we had already done research of the mattress we wanted, it was such a smooth process. We were in and out in under 45 mins (maybe even 30)! I would recommend this location for your mattress and bedding needs. :)

Billy helped me out on a Saturday evening and he was great. Asked me about my preferences and then showed me a couple of mattresses that matched my preferences and some that were outside just to confirm what I liked. He helped me understand the differences and didn't shy away from showing me as many mattresses as I needed to find the one I liked. Never pressured me at all to make a sale. I ended up going with a Serta perfect sleeper medium. Also gave me a nice discount on top of the sale. Definitely ask for Billy if you're looking for a mattress.
