Rated 5 out of 5 by from They make it right!! Bought memory foam mattresses one month ago. Never slept on this type before. Wentzville store Mgr let us know of 120 exchange policy. We just couldn't get used to the mattress. We went back and another associate- JAY took over an hour with us to trouble shoot our issues and found us the goldilocks of mattresses!!!! We have bought multiple mattresses from Mattresss firm over the years and will continue to do so based on their customer service. One suggestion- delivery crews differ. Some are great. Some not so much. Need more consistency and professional drivers with a mattress firm marked truck.

Rated 4 out of 5 by from store service not so much I love the mattress and the sales staff at the wentzville, mo location were great. The delivery persons contacted me as they said they would but with their windows down in their van could hardly hear them. When they showed up my sons were there to show them where to place mattress..that was all fine. When I got home and got ready to make up the bed I noticed that all the lining on the bottom of the box springs was barely hanging on. It was clear to see that this had come off when they placed it in the room but they made no mention of it to my son's. Because I don't want to go through the trouble of sending it back I will acquire a staple gun and fix it myself. Just not what I expected.

Rated 5 out of 5 by from Excellent service! We stopped by to check out a Labor Day door buster deal on a $99 mattress. Usually the sales rep will try to up sell you right off the bat. Not the case here. They showed us the sale item and explained everything about it, and then gave us time to browse the rest of the store. We found a more expensive mattress that we liked a lot better but was a little over our budget. They worked with us to bring the price down to a more comfortable number and we ended up getting a box spring and frame as well. We got friendly, no pressure service and left with a great deal! Mattress Firm will be our first stop from now on and we will highly recommend them to our friends and family.

Rated 2 out of 5 by from The Good, the Bad, and the Ugly My initial experience with Mattress Firm was good. My sales representitive seemed knowledgable and sincere. However after my purchase on May 26th, 2020, and a promise date of a May 29th, 2020 delivery I received a call, informing me that my new bed would not arrive until around June 18th, 2020. When I called to confirm the June 18th, 2020 delivery date, I was informed that my merchandise could be delivered unitl July 2nd. Well, I had to call again to confirm the July 2nd day, and am now expecting my delivery tomorrow. I guess we will see if this holds true.

Rated 5 out of 5 by from Brian was great Brian explained everything about a power bed frame and he matched the price I found for a similar bed frame online that was similar but actually didn't have one of the features of the frame I bought. He explained about the different mattresses which helped because there are so many more choices since I purchased my last memory foam mattress. I really liked that they have them color coated for soft, medium and firm... cuts down on the number of mattresses you need to lay on in the store. I had a lot of questions and he patiently answered all of them, made suggestions based the answers... it was the easiest purchase of a bed I've had and I'm 60 years old so I've bought a few.

Rated 1 out of 5 by from Poor Customer Service after Purchase We purchased a mattress, mattress cover and headboard on Presidents Day. Only the mattress and headboard were delivered the next day. Called store four times to inquire about brackets for headboard and mattress cover, each time someone took our number and said they would call later that day to provide update. Those calls never came. My husband finally went to the store to inquire about brackets and cover. Finally, a month later we have our headboard and mattress cover. Poor customer service!

Rated 3 out of 5 by from Sales and showroom staff were great.... But Sales and showroom staff were great.... Stephanie was fun to work with, open, honest and knowledgable. We love our new Tempurpedic mattress, but delivery was another thing. They brought the wrong base so we're now waiting on the replacement base.... Nothing definitively rescheduled yet. A better system for loading the truck with a check and balance of the orders to go out against a SKU or model name/number of what's being delivered against the deliveries

Rated 5 out of 5 by from outstanding customer service We bought a mattress which we knew we didn't like right away. It was comfortable in showroom but found to be very unsupportive when we got it home. I called and spoke to Chuck the next day. He recommended we give it a little more time but if I was sure I could go ahead and exchange it. We went in to the store that day and he happily helped us to find the best mattress for us and had it delivered and the previous new mattress exchanged within 48hrs. Chuck is very knowledgeable about mattresses. He's been in the field a long time. We ended with a Simmons beauty rest providence which we really like. It is 3 inches less wide than our previous queen but now the sheets fit better because with the pillow top you need that extra material. If you don't know which mattress would be best for you or worried about being stuck with a mattress you are unhappy , talk to Chuck and I think he'll steer you straight
