Rated 3 out of 5 by from Mattress Purchase My husband and I had a good experience with our salesperson although we were very disappointed with the disconnect Mattress Firm has with the Delivery Company they use for deliveries. Information provided by the salesperson directly contradicted information provided by the delivery company concerning the ability to get the mattress into a narrow space. This confusion caused the delivery to be delayed, we had to get the mattress into the space which wasn’t an easy task ourselves, and the lack of communication between Matress Firm and the people delivering the product forced us, as the customer, to act as a go-between. Our confidence in our purchase suffered.

Rated 5 out of 5 by from Brandi is the best!!! My husband and I dreaded the trip of finding a new mattress and bed only because of all the options you can get lost in, and then we walked into Mattress Firm South County Supercenter and met Brandi! She made this trip exceptionally easy to say the least!!! Without even realizing how she was narrowing down the options, it wasn’t long until my husband and I found the bed for us! She was so helpfully explaining the reasons for all the different options and took the time to make sure she understood our wants. The store has a great variety of options, and Brandi is the person you want to be working with!!! She is awesome at her job all the way around.

Rated 5 out of 5 by from Great Service I purchased my mattress last week. The salesman, Greg, was incredible. He understood exactly what I wanted and made sure I was happy with what I purchased. There was no pressure at all when selecting a mattress. He took me through the process of trying out each bed that fit my comfort and sleep style. Before making my purchase, I mentioned that I needed time to relocate the mattress I already had to my basement and replace it with the mattress I was sleeping on. He explained that even though I didn't want delivery, I could pick the mattress up at the store at my convenience. I was very impressed with everything offered to me. It really was a great experience!

Rated 5 out of 5 by from Excellent personal service We were all over looking for a mattress that suited our needs, and most places wanted to upsell us on specialty frames, pillows, etc. Sean gave us a quick rundown on how to navigate the store and then had to tend to the other customers that arrived before us. When it was our turn, he skillfully answered all of our questions with great expertise, and addressed our concerns with such confidence that we bought a mattress/box spring set that night, which was not our intention. He set up quick delivery that fit our schedule, and we've been sleeping great ever since that night we just by chance stopped in to "look". We couldn't recommend this store and Sean more highly.

Rated 5 out of 5 by from Wonderful purchasing experience Wonderful purchasing experience, from the showroom to the delivery. Sales associates Brandi and Greg were extremely helpful with my purchase. I told Brandi about my situation and she was able to suggest a mattress from her own real life experiences, that she knew would work for my father. My 88 year old father has slept on the new mattress for 2 nights now and has thanked me multiple times for getting him this mattress, since he wasn't up to picking it out himself. If you are in the market for a new mattress, especially the i500 series memory foam, contact Brandi or Greg, they won't steer you wrong.

Rated 5 out of 5 by from Easy transaction! I needed a full size box spring, but instead of the ordinary 9 inch, I wanted a 5 inch. I didn't feel like shopping, so I called and spoke with Greg. He quickly and courteously provided me with all the information I needed to make a purchase. Because of ordering a 5 inch, the delivery took a few days longer, but not unreasonable. I had the mattress on the 7 day mark and it was delivered and set up quickly without a hitch. I'm very happy with the box spring and how Greg was able to point me in the right direction as far as my decision was concerned regarding steel vs. wood.

Rated 3 out of 5 by from Uncomfortable bed My husband insisted we buy our mattress here. I thought it was way overpriced. This mattress is nothing like the one we laid on at the store and we have to wait another 3 weeks before we can exchange it. They delivered the mattress last Friday and I haven't slept well since, every day I've woken up dizzy, my neck and back hurt, and I have a migraine headache. My husband hasn't slept well either, but has not had as many problems as I have with it. We are not old, three years ago I was sleeping on a cot for a missions trip that almost as uncomfortable as this mattress.

Rated 5 out of 5 by from Service from beginning to end I walked into the store already knowing the features I wanted in an adjustable frame. Brandi, my sales rep, matched my request perfectly without trying to upsale me. I appreciate that. Other stores in my search had lost my sale because they couldn’t match my requirements or the upsale was a turn off. I felt informed and listened to. Delivery went well (as described)- on time without a hitch. I am enjoying my bed. Good service and product! I will be recommending!
