Rated 2 out of 5 by from Replacement mattress also must be replaced All the people I have dealt with have been super nice. And the mattress was only in the $350 range, but it is for a guest room. After only about a total of 20 off and on nights of use the cording was coming off the corner and it had a significant sag in the middle. It was kind of a hassle to go through the warranty/replacement process, but again everyone was very nice. However, the replacement has arrived and it is not sewn properly along that corded area.The fabric is loose and you can see the foam underneath. I have to go through the warranty/replacement process AGAIN. This is inconvenient, frustrating and a hassle.

Rated 5 out of 5 by from Great mattresses and service!!!!! I had been having hip and low back pain for awhile. My old memory foam mattress would dip where I had been and had not rebounded for a long time (almost from when they had been bought-early 2000's). Martin was great!! I told him what I had and what I did and did not want. He recommended mattresses and I tried them out. He spent time with me and answered all my questions! I have been sleeping with my new mattresses for 10 days now and I love them!! My hip and back pain are gone and I have more energy during the day since I am not hurting! Thank you Martin and Mattress Firm!!!!!

Rated 5 out of 5 by from Super experience! Came in Sunday to purchase a new mattress for my daughter. Salesperson was informative, but not pushy. Made decision quickly. Variety of mattresses prices and quality levels. He helped us make the best decision for us. They were able to deliver two days later. Great communication from delivery guys, best I've ever experienced. They were there exactly as they said they would be. 15 minutes later old mattress is out and new is installed. Very professional. Would definitely return for my next mattress purchase.

Rated 5 out of 5 by from Good experience all around I am very happy with my Sealy Deveraux mattress. David Little at the Clinton Highway Mattress Firm store in Knoxville, TN was great to work with on my mattress purchase. He was totally professional, polite, super knowledgeable about mattress construction and materials, very patient with all my questions and concerns, and did not come across as a high-pressure salesman. I wasn't expecting my experience at a chain store to be very remarkable, but I was pleasantly surprised!

Rated 4 out of 5 by from The store service was not as good as previously This is the fourth mattress I have purchased from Rolf Vann and I really like him and appreciate him very much. The only problem with this delivery was that they did not deliver the box springs with the mattress and the delivery service couldn't go back and get one. I had to borrow a truck and pick it up myself. This purchase was a gift for my daughter and I had to leave work to do this.

Rated 5 out of 5 by from Buy Here - don't waste time shopping I am Powell resident. Went here after shopping the other local Powell mattress options. Absolutely shocked by Mattress Firm's lower prices, delivery, service, and extras. Staff (Rolf) was amazing. Knowledgeable, friendly, not pushy; exactly what you want for the mattress buying experience. I will not even bother going elsewhere in the future. This is the 1st and only stop needed.

Rated 5 out of 5 by from Excellent customer service! This is our 3rd time buying from Mattress Firm and so that shows we have had good luck with them. This time around I think we had the absolute best customer service of all time! Michael T. and Rolf V. both helped us, and they were a pleasure to work with. No big sales gimmicks, no pressure, just kind and professional.

Rated 5 out of 5 by from Michael was fantastic Spent nearly two hours in the store. Michael was friendly, attentive, informative and just overall fantastic! I left to go think about it and was back within the hour to place my order. I know he typically isn't at this particular location, but I'm happy and grateful he was. A+ across the board.
