Rated 5 out of 5 by from Wonderful experience! My husband and I were shopping around for a mattress over the weekend and the first place we thought of was the store on Sunrise Highway that used to be Sleepys. We had a couple of very good experiences there with a salesman named Mike who, in the past, had sold us a mattress. When we entered the store, we noticed Mike was there but with a customer. Rose approached us. She was so friendly and was extremely knowledgeable! She spent a lot of time with us making sure that we understood the differences of each mattress before deciding which one we would choose, We're very happy with our purchase and will recommend this store and it's sales staff!

Rated 5 out of 5 by from Exemplary service! Visited the Wantagh store this past weekend. We came at the right time as the Labor Day sales traffic was only just starting to pick up. Despite a few families in the store, the rep, Lynn was incredibly attentive, and not at the expense of other customers. She and her colleague moved back and forth between each of us seamlessly and even had us talking together and comparing notes. They were incredibly friendly, welcoming, professional and knowledgeable. My husband and I have already recommended the store to 2 other family members looking to purchase in the next few months.

Rated 5 out of 5 by from A#1+ experience! My experience with this Mattress Firm location at 3235 Sunrise Hwy, Wantagh, N.Y., and specifically with a gentleman named Ed was A#1+! Or should I say excellent! And I don't throw that term out lightly or often. Ed, who I think may have been or is a manager was so very helpfull and knowledgeable and friendly. After I told him of the problems that my mother and I had with a particular furniture store (he knew exactly the one and knew of others similar complaints), he asked questions and made some suggestions. The mattress we chose was delivered the same day and installed more quickly than we thought possible! My mother says that the mattress is super comfortable and that she gets a good nights sleep every night! Thank you Mattress Firm! And Thank YOU so much Ed!!

Rated 5 out of 5 by from GREAT CUSTOMER SERVICE Read a lot of reviews on line and most of them mentioned Ed the salesman. Was not sure how this was going to go since it had been 10 years since I had gone shopping for a new bed. From the moment we arrived we felt that we were off to a good start. He was not pushy! After a few important questions he pointed us to the direction of the beds that met our needs and from there he would check on us now and then without being annoying or persistent! Answered all our questions and overall it was a Great EXPERIENCE!

Rated 5 out of 5 by from Great experience Recently visited the Mattress Firm in Wantagh NY and was helped by Edward T. I don't usually write reviews but he was so helpful and knowledgeable I felt I had to spread the word. We have purchased beds from Sleepy's in the past and Edward T was also our salesperson. We will only go to the stores he is located in because we know we will get the information that we need. Great guy, great service, great experience. Thank you Edward T. We look forward to buying beds from you in the future.

Rated 5 out of 5 by from High quality customer service I went to the wantagh location to purchase a mattress for my son. The salesman Michael was very friendly and accommodating. He helped me with my son who didn't want to stay in one place. He was able to narrow down my search quickly with the description of what I said I was looking for. I was in and out within 30 minutes which was the perfect amount of time. I will definitely go back and purchase another mattress from Mike.

Rated 5 out of 5 by from Dedicated! I never really write reviews but in this case had to. Recently purchased a mattress/bed from Mattress Firm in Wantagh. From the minute I walked into the store through the delivery, it was a terrific experience. The manager Ed and our salesperson Kathy were awesome! Their professionalism, knowledge, dedication and personalized attention in finding me the perfect mattress, was over the top. Thank you Wantagh Mattress Firm!
