Rated 5 out of 5 by from I'm their customer for life! This was the first time my wife and I buy a mattress and we had a great, fun experience. Farides, the sales rep, was very personable, insightful and patient. She stayed well over closing hours to see that we got the bed we wanted. She even helped us with a discount on delivery. The delivery was fast and punctual. The guys were respectful and careful going up and down my stairs. We've slept in our mattress for five nights, and thus far, my wife has no more back pains and I'm dreaming again! When my family grows, I'll be sure to return to this Mattress Firm location. Very happy and blessed to have been served by Farides.

Rated 4 out of 5 by from Very professional... My fiancé and I purchased a new temper pedic mattress. We did a lot of research before deciding on the right mattress and felt that Mattress firm gave us the best value (as they don't really discount tempur medics). They included credit that we applied towards shipping, pillows and mattress protectors. Their availability for delivery was great and the staff professional. Only thing would be that I bought the shaped gel pillows from the store...they are a bit hard...harder than the sample on the floor. Hoping that it softens up after a while. Although perfectly shaped, feels like sleeping on a rock!

Rated 1 out of 5 by from Product Issues The manager refused a refund when I told him that the mattress causes me neck and back pain. Severe neck and back pain that I cannot have for another night. I am not satisfied with the product and want a full refund. It is not fair that a mattress causes me excruciating pain. I am the type of person that would recommend go service to anyone but I am really disappointed with this issue.

Rated 5 out of 5 by from The service was great! The purchase of this new mattress was a necessity due to my wife's back problems. She is very pleased and satisfied, so far, with the purchase. I must mention that the sales lady at the store was very professional and friendly. Also the delivery driver, Mauricio and his assistant, were very professional and careful in handling and installing the new mattress in the bedroom. I was truly amazed how quickly and easy Mattress Firm made this purchase possible---from purchase to delivery- Kudos for you!!! Thank you!

Rated 5 out of 5 by from Very satisfied My experience with Mattress firm was outstanding. From my visit with the salesman at the location on Flagler and 84 ave in Miami, to delivery it was smooth and fast.The salesman helped me choose a mattress that fit my budget, and the purpose (bunk beds). I scheduled the delivery but actually received my bed frame early and needed a quicker delivery date. Mattress firm was able to accommodate my request exactly as I needed. Very very happy!

Rated 5 out of 5 by from Great experience and really good customer service First I would like to thank Arturo and Sonia for such a good job finding what we were looking for they have a really good customer service. after searching in different locations we decided to go back because of the way they treated us and the knowledge about the merchandise they are selling. Arturo went out of his ways to help us find what we wanted, so for that I highly recommend to visit them and make your purchase with them.

Rated 1 out of 5 by from AWFUL SERVICE !!! I purchased a TULO Two cool pillows and a box spring and I went back on the weekend for the special they had going on a Colombian man was helping us throughout the purchase without any problem. Then later an elderly later came and took care of us because the other man was busy then the most awful thing happened. This lady started eating right in front of us while talking to us with her mouth wide open and talking to us in a super rude way!!! I asked if she can Kindly let me know how much the bill will end up in she later passed me the calculator and said for me to do the calculations because she was to busy eating and not only that she put sauce all over the calculator so when I grabbed it I got my hands dirty from her food. I got up and told my husband lets GO !!! She also kept on yelling at the other man working with her so rude when the man was just trying to help her out!!!
