Rated 5 out of 5 by from Great staff, the place to go! You can buy a bed anywhere, but when you want the best you go to a specialist. That's what brought me to Mattress Firm. The Jason 'The Guy with the Bow-tie' and Coann took the time to take me through every bed offered and even a few that weren't to help me find the perfect fit. (And I tried them all) Besides being patient with me, what really stuck out was the conversation we had while deciding. You expect the sales staff to steer you to a bad with high profit or good commission. Coann led me to what was best for me, even though the bed I chose didn't bolster her numbers. The next time I get a mattress, this is definitely the place I am coming to. And I suggest you go there too.

Rated 5 out of 5 by from Great Experience Mattress Firm was our first stop when we began mattress shopping. The sales representative was very friendly and knowledgeable. We told her the specific mattress we were looking for. She took us right to it, but also showed us other models. We appreciated that she did not push the higher-priced mattress on us. After visiting several other mattress stores, we went back to Mattress Firm and purchased the model we were looking for. Great customer service made us even more happy with our purchase. Couldn't have asked for a better experience.

Rated 5 out of 5 by from Above the call of duty I'm was just witness to Matress Firm staff going above the call to help out a customer with a problem. The customer called in with a problem of moving an old matress from one room to another to make way for their new purchase. While the moving is handled by a secondary company, and is outside the usual fare, Coann (the Matress Firm employee) was willing to help the customer through the situation and even willing to come over and personally move the matress. That's what I call giving 120%. If you ever need a matress or have questions this is the location I would come to.

Rated 4 out of 5 by from Quick, Easy, Fast Rewarding experience! I went in and was met right away by a young man wearing a bowtie :) He explained how the mattresses were arranged by firmness. I found the one I wanted and my husband picked it up the next day. I have slept on it for almost a week and have slept in total comfort.Since I do not get around well, I was VERY pleased with the service and the fact he explained the guarantee to me. Thank You

Rated 5 out of 5 by from I love my new bed. I went to Mattress Firm last Sunday and by Monday night I was sleeping on my new bed. I bought a Sealy Posturepedic mattress and box springs. It is so comfortable. Since I got the bed I have been sleeping very well. Both of the salespeople were very helpful. I tried several different mattresses while at the store. They even offered me a pillow to test the mattresses properly!!

Rated 5 out of 5 by from Very Knowledgable I walked in and the Bow tie guy as he called himself was so helpful, full of information and helped me to pick out the Perfect mattress for my needs. I also like their warranty and ability to return the mattress within a specified amount of time should I not like the mattress. They are willing to do whatever it takes to please the customer. However, I can tell you that I love my mattress, the service and the location was well organized and visually appealing. I highly recommend this store and the manager.

Rated 5 out of 5 by from Friendly, knowledgeable, easy to work with I came in to get a twin bed for my daughter and enter a claim for my old mattress. They were pressure free and didnt try to push any higher priced products. They even faxed in my warranty claim and said don't hesitate to call with any questions.

Rated 5 out of 5 by from Great Crew We really didn't know what to expect but Sierra and Jimmie were great! We felt we were fully educated and we got the mattress that really matches us! Thanks again.
