Rated 5 out of 5 by from Phenomenal Service! I hadn't bought a mattress ever, and was quite unsure of what I was looking for! I entered the store feeling overwhelmed and unsure of where to begin and the staff stepped in and guided me the whole way! The staff at Sleep Train were excellent at showing me a variety of beds and whittling down what I liked and did not like! I never once felt uncomfortable as I thought I would (randomly laying on multiple beds in public!). And the staff were extremely knowledgeable! I was given all the information I would possible need to make an informed decision! I was blown away by the customer service! They went above and beyond what I expected!

Rated 4 out of 5 by from Time well spent Jon, our sales representative spent a lot of time with me and my husband and sister. We were buying two beds and he worked with us going back and forth showing us new beds. He did show us the more expensive beds first but he showed us our other options as we stepped down in price and helped explain why we might like one bed more than another. He did not rush us and he really paid attention to what we said about our likes and dislikes. He arranged for a complimentary after hours week day delivery because my husband and I both work until five. He was fun to work with and overall it was a pleasant experience. Thank you!

Rated 5 out of 5 by from Very knowledgeable and great service We made two visits to the store. The first to see how the product had changed since the purchase of our 1st 3 tempurpedic mattresses. (master and 2 guest rooms) We learned which one was comparable to our current mattress. Since our first mattresses were purchased 4 years ago they don't have the current heat dissipating technology so we learned about bamboo sheets to make those less war. We narrowed it down to two for our 2nd residence. Eve was very helpful, professional and knowledgeable. On return Eve was off so we worked with the manager and again had excellent service. The delivery was set for the next day and went smoothly. The new mattress was great.

Rated 5 out of 5 by from Customer Service You know those tasks in life you hate and dread doing like going to the Post Office? Well buying a new mattress was one of those tasks for me. When we bought our current mattress through Sleep Train a few years ago, we had outstanding service. I was cautiously hopeful but dreaded being disappointed. However, this time was even better than our last experience! That never happens! I always hope the person I speak with is professional and knowledgeable but this was met and exceeded. I even called back to rave about the Salesman, Kole, and his Manager was just as awesome! I will highly recommend Sleep Train to everyone we know.

Rated 4 out of 5 by from Amanda was great After an earlier visit to the store I was going to a competitive. There was a sleep train next to the competitor and I decided I could walk in and see if after my so so experience sleep train could up there game. Amanda did, she found me a better deal then I was going to get but also took the time to walk me through a few other options. She was not just trying to make money but maker certain I made the right decision for me. I ended up getting something different but I feel comfortable with the decision. The first experience felt like a car salesman. The second was a person trying to help me- it made a world of difference.

Rated 5 out of 5 by from Great customer service and products Last week I went into the Northgate Way Sleep Train location to look at a new mattress. The Sales Person Eve was very helpful in finding the mattress that would work for me specifically. I tried many different beds and found the perfect one for me. I did not feel rushed or pressured to purchase a mattress that I did not like. Furthermore, I did not feel any pressure to purchase a more expensive one. I truly felt her goal was to help me find one that would work for me. I was impressed by the entire team from start to finish all the way down to the guys delivering my mattress and other products. I would highly recommend them to anyone looking for a new matress or matress products.

Rated 4 out of 5 by from Pleased with mattress! We first went to the used and new mattress building and found a new mattress we liked. The salesman was informative and told us the price including box spring. We decided to view the new mattress area across the street, which is the same company, and found the same mattress for $200 less. We chose a latest model instead. The 2nd salesman was also courteous, friendly, and informative, but obviously the 2 salesman were not on the same page for prices. One thing we found surprising was the 2nd salesman never mentioned a need or no-need for a box spring, which we felt should have been part of his sales presentation or question.

Rated 1 out of 5 by from lousy robo call scheduling of deliveries I purchased a bed a mattress a month ago. I have received two robo calls cancelling scheduled deliveries just a half day before the scheduled delivery date on weekends, causing me to waste two weekends at home that I could have left town. The third robo call was left on my answering machine yesterday, telling me to press one to acknowledge that I would be home to accept delivery this weekend. Since the message was on my answering machine, I was not able to accept delivery, and the robo call did not provide a phone number to call back. I've called the local store and the 800 number on the website, and no one answers. The delivery system is completely automated and provides no opportunity to respond, wasting customers' time. I would NOT recommend dealing with this company.
