Rated 5 out of 5 by from AMAZING SERVICES!! On Friday August 11th 2016. I walked into mattress firm in Marathon Florida. I was greeted the moment I walked to the store by Bam Bam. He was nothing but courteous to me. I explained to him I didn't want to spend an outrageous amount on a mattress along with my back issues. He pointed out the mattress that was right for me physically and financially. Not too mention his personality sold me. I left there with the mattress, a cover, bunkie board and a black ice pillow. Monday I went for my order brought it home. Couldn't have been more satisfied. I will be dpingnore business with him in the next few months. Thank you Bam Bam! Sincerely, A very impressed customers Jennifer Hargrave... I gave a 5 star review to him. He well earned every star and then some!!

Rated 5 out of 5 by from Way to Welcome! We had to buy at least one bed, and Jose (Edric) who waited on us was amazingly helpful. He had so much information about our choices, and we were so comfortable shopping in the store that we went ahead and bought two. Not only that but when Edric found out we were new in town, he offered helpful advise and a great lunch tip, which proved to be one of the best restaurant recommendations we've had in Marathon. Way to know how to greet a new neighbor, Edric at Mattress Firm and earn a loyal customer! Thank you!!

Rated 5 out of 5 by from Great service! Had a great experience in the Marathon, FL location! Service was great - several options and we got the most comfortable bed I have ever slept on!!! I ended up getting the Key Wedt firm mattress it is latex mattress which I had never heard of, but the salesperson was very knowledgable and explained all the details. I am so happy with my purchase - this is the I have been searching for!!

Rated 5 out of 5 by from Very Friendly and Helpful Employees! I went to the new store in Marathon, FL for the first time to get a mattress cover that I saw advertised in the Black Friday sale paper. The 2 gentlemen working were so helpful and friendly. They made super I had found the proper one and then registered it for me online to make sure I had the warranty. They gave me extra care tips as well! Impeccable service!

Rated 1 out of 5 by from Still waiting for refund of cancelled order We purchased a mattress and later that day cancelled the order knowing there was that money back promise. The tried to deliver the order and we refused delivery as instructed. We are still waiting for our refund a full 2 weeks later. Local store staff were nice enough and very helpful, but this is unacceptable service from Mattress Firm.

Rated 5 out of 5 by from A pleasant Suprise! I'd never been in this store and just assumed it would be overpriced.......After a friend recommended I check there before buying what I thought was affordable, I went in and was so surprised. Jimmy, was so helpful and gave such a great explanation that helped me make my selection very easy.

Rated 5 out of 5 by from Smooth as silk. No issues here. The salesman at the Marathon, FL store was helpful and not too pushy (which is always a plus). Delivery was communicated via automated telephone message which was a pleasure and delivery men were courteous and on time. So, all in all, a perfect purchase without issues.
