Rated 5 out of 5 by from Great Overall Experience We stopped at a local Mattress Firm store with the idea of trying out the Temperpedic mattresses to alleviate my husband's back/leg pain. Our salesperson was really knowledgeable about each variety of the mattress--and there are MANY. No high pressure, just an honest effort to see which mattress/pillow combo worked best for each of us. He stayed late to do this! Our purchases were delivered and set up at a time convenient for us--very professionally. We bought our last mattress set from Mattress Firm six years ago and (if we live long enough) will buy future sets from them. There is no aspect of the purchasing experience that was not great.

Rated 3 out of 5 by from Good experience Our experience was overall pretty good. The one thing that frustrated us was we were not offered the sale/deal that was going on. We spent over $1200 and the only thing we were told came with it was a free box spring or adjustable base. We chose the adjustable base. The next day I saw an ad pop up on social media that said if you spent $799 you got a base, 2 memory pillows and a mattress protector. We called to see if our purchase qualified for this and were told yes but they were out of the memory pillows. It is only while supplies last. I just wonder if he would have told us about it the day before, if they would have still had pillows.

Rated 5 out of 5 by from Good fun and a good time It was definitely one of my first time's that i've walked into any mattress store and talked to the salesman without feeling pressured to get something expensive. I got a pillowtop queen bed and its my first bed that isn't just a standard coil bed. I love it and have never slept better, i get about 5-6 hours of sleep and feel like i slept for 9 before i get up to leave for work. The only problem is i never want to get out of it. The service was just as great. The salesman had a great sense of humor and my brother and I thoroughly enjoyed talking to him and my fiance' and I feel like we got the best bang for our buck. I highly recommend this Mattress Firm.

Rated 5 out of 5 by from Honest and a Great Deal Shopping for a new mattress is not your everyday event, so when you have to get out there, your hopes are to find the right mattress and one that will fit your budget without breaking your back and the bank account. After all, more than 60% of the time is getting rest from the struggles of the day. Like any product and service, the sales person is there to inform and to be a Ambassador for the company. I would like to thank Bob Ringland, our sales rep, for not only taking the time to explain the models but to find that perfect. His friendly, honest approach was refreshing. Thank you Mattress Firm! We will share the good news about your comapny.

Rated 5 out of 5 by from Staff made it a painless and fun experience! I was actually a little nervous about shopping for a new bed - we had put it off far too long. Beds are expensive and you don't want to make a mistake - it can be quite an investment. We were greeted by a funny and charming salesman who quickly determined what we needed to focus on - he was obviously very knowledgeable about his inventory and the industry in general. Once he figured out what category we fit into (ORANGE!) it was fairly simple to narrow it down from there. But the process still took several hours and both staff members were extremely helpful and patient. We never felt pressured or rushed. I learned a lot. I will never shop anywhere else for a bed.

Rated 4 out of 5 by from Speedy We purchased our last mattress from Mattress Firm 11 years ago and were very happy! We needed another one ASAP! Went in on a Saturday night right before closing and got a mattress delivered in 24 hours! The delivery was unbelievably speedy they were in and out in 10 min! However, I was not so impressed with the way my mattress was handled on delivery. I saw the delivery man basically tumbling my new $2000 mattress down the side walk end over end!!! I called the store to report it just in case there is internal damage to my mattress.

Rated 5 out of 5 by from GREAT BUY/NO PRESSURE I did a good bit of research and shopped around. When I got to Mattress Firm the salesman was friendly and knowledgeable but not pushy. He answered all my questions and did not try sell me a mattress that I did not want. I was surprised that the mattress was delivered the next day, which happened to be a Sunday. The delivery men were polite and cautious when moving the old mattress out. As for the Mattress itself. Great! I will never go back to the old inner spring style. Gel cooled memory foam is the way to go.

Rated 4 out of 5 by from New Mattress I stopped by the store one day to check out mattresses - mine was 16 years old. I told them what I was looking for and received excellent service and information on finding the right mattress for me. I went back later and ordered my mattress; worked with Brian W on both trips. Delivery was as scheduled and my only problem is figuring out how to get up on the bed as I have short legs and the end product is higher than anticipated. Probably my fault for not checking during the set up.
