Rated 5 out of 5 by from Great Service - Great Mattress! Visited the store in Brentwood Promenade. We were a little taken aback by the first gentleman to greet us. Felt like a typical salesman. Fortunately, he had to leave us to take care of a previous customer, so we were able to get help from Chris. I am so incredibly happy that this happened. Chris walked us through the store, pointing out the benefits of each mattress, and did not pressure us to buy any one item. He did offer some up-sells, as I would expect, and we did buy a new mattress protector as a result. We were in and out of the store in under an hour, with the new mattress set to be delivered the next day. Low-pressure. Knowledgeable staff. Great product. Great price. 10/10, would shop again.

Rated 5 out of 5 by from 2ND Mile Service Chris, Joe, and Dakota made the "desperately-searching-for-a-mattress-so-I-can-sleep-at-night" experience so much more easy and enjoyable than I had anticipated. I went in with very little knowledge, a budget, and a tired body and left confident that I'd gotten the right mattress at a reasonable price. Now I love my new mattress and have all the well-rested energy I need to keep up with my fast-paced work environment up the hill from this Mattess Firm location at Chick-fil-A! Thank you, and well done, guys!

Rated 5 out of 5 by from Excellently customer service! My wife and I went into the Mattress Firm store to start the process of learning about mattresses. We did not intend on purchasing that day! We met Greg and told him we hadn't yet started our research, to which he responded that that is his job! We spent the next hour learning from Greg and testing mattresses. We left with a wonderful mattress and two new pillows. We highly recommend Mattress Firm, and specifically Greg at the Brentwood location in St. Louis. He is an excellent salesman and very nice man.

Rated 5 out of 5 by from Great experience Greg was very professional and informative, but warm and friendly at the same time. He was sensitive to my needs and didn't use high pressure sales tavtics. He honored the price match guarantee and even gave me a better quality mattress. There is definitely room for improvement with the computerized delivery scheduler but once the delivery time was set the delivery men were very nice, efficient and professional. It was an overall great experience.

Rated 1 out of 5 by from Unsatisfactory Service I purchased two pillows on 7/21/18. They were ordered from another store to be picked up on 9/1/18. I called the store on 8/31/18 and was told the pillows were available to be picked up. When I arrived at the store the pillows weren't there. The reason for the poor service was unacceptable. There was no attempt to correct the error or to deliver the pillows to my home. I won't shop at Mattress Firm again.

Rated 5 out of 5 by from Great Experience! Greg was very knowledgeable and friendly! He was informative and low pressure, which was a pleasant surprise. He was patient while my wife and I were indecisive, while providing suggestions as we tried to determine which bed was best for us. At the end of the day, we were very pleased with the experience and definitely chose the right store to purchase our new bed!

Rated 5 out of 5 by from Very pleased After looking at all my options, I was excited to purchase a mattress that was not on my radar when I walked through the door. Salesman was very knowledgeable and addressed all my concerns and introduced me to new concepts in mattresses. I’m 61; wanted a mattress similar to what I’ve slept on for decades. I am very pleased with the service I received.
