Rated 3 out of 5 by from Great Staff, but Complicated Point of Sale Staff was knowledgeable, helpful and answered all questions but the checkout process was way too long, complicated and had confusing pricing (offers, rebates not straightforward, tables and spreadsheets). I am happy with the product and the sales staff, but checkout was way more complicated than buying a car. Streamlining the sales/checkout process company wide is strongly recommended as the current system is cumbersome, confusing and way too time consuming for a simple mattress purchase. Unfortunately, the inefficiency of the process/checkout/billing seemed too difficult to understand for both new and veteran employees and may leave some customers frustrated.

Rated 5 out of 5 by from Great Service, Great Mattress Ty was the most informed salesperson I have come across in a very long time. answered all my questions and concerns. Couldn't have been nicer. Found me the perfect mattress for my needs and price range. The bed was delivered and set up by three guys who were so fast my head was spinning. They were helpful with advice on where to put it and other issues that I had. Loved everyone I dealt with and couldn't have had a better experience. Will be needing another bed in about a year for the guest bedroom and will definitely go back to this store and hopefully to the same salesperson.

Rated 5 out of 5 by from Great experience helpful service This was the first time I was purchasing a nice mattress. I didn't know what to expect or how to go about it. When I got there my sales associate was awesome. James Mills was my sales associate and he was spectacular. He was very informational about all the different brands and types of mattresses. He was not pushy and was very helpful on my budget. He showed me the differences between a higher quality and lower quality mattress. James was so helpful and I will definitely go back. The store was nice and easy to get to and the service was exceptional and very professional.

Rated 5 out of 5 by from Mattress Buying Made Easy My wife and I just purchased a split king mattress from Mattress Firm. The salespeople were very knowledgeable, and helped us to find exactly the right mattress to satisfy both of us. This might sound simple, but my wife and I have very different sleeping preferences, so it took some time for the store manager to find just the right solution to fit our needs. He was very patient with us as we tested almost every mattress in their store, and made us both feel welcome to do so. It's been over two weeks now, and we are still loving the new mattress. Thank you Mattress Firm!

Rated 3 out of 5 by from Mixed bag The salesman way overpromised on what the delivery people would do. I wanted one bed out, but the bed I was replacing moved to the other bedroom. I was told they would take the one metal bed frame away and move the bed I was keeping. When the delivery guys came, they said they don't take away metal bed frames or move anything from one room to another. So the mattress & box spring ended up blocking my closet, the headboard blocking my dresser drawers, and the metal bed frame up against the wall. Had I know this I would not have bought the bed. After a number of phone calls back and forth, Trevor, the area manager, came himself at 8:15 p.m. and with some help from me got it all taken care of, so 5 stars for him. They also promised price match. Waiting to see what they'll do about that as I just found a less expensive one online.

Rated 2 out of 5 by from Great product, terrible delivery service We were promised next-day delivery on a queen mattress set with a 6-9pm delivery window on a Friday night. Got a phone call at 9pm from the delivery truck saying there were 4 orders in front of us and they'd call when they were on their way. At 10pm, I called them and cancelled the delivery because I don't want people I don't know in my house after 10pm. Took two more days to get the mattress delivered and there was no option for compensation for their failure to deliver on time. I spent far more time waiting for my mattress to be delivered than I expected.

Rated 5 out of 5 by from GREAT SERVICE Tyler was wonderful. I had called to ask about the memorial day sale to see if the promo of a free adjustable frame was still going on, He informed me that it wasn't but he still could work something out. I was going to see another company/store to see what they offered but told Tyler I would swing by after. I did and Tyler didn't disappoint. I told him what the other store was offering and he was able to match and then some! He saved me about $200! I really appreciate his willingness to help. I would def recommend to my friends and family.

Rated 5 out of 5 by from Great & fast service!! DONE & DONE! So happy! Our sales person Tyler let us in 30 mins early and took care of us right away. They had a promo going which they usually do. The mattress we wanted was not in stock at the store so we had to drive to warehouse to get the upgraded version. Thankfully Tyler still gave us the promo deal! He was so nice & helpful made this experience let stressful than I thought it would be!
