I had a great experience with Justin at the South Bay location. I was looking for a basic twin mattress and frame for my brother who is staying with me for a couple of weeks, which I found at a great price. After mentioning to Justin that I would be looking into purchasing an adjustable queen base for my new mattress at the end of the year, Justin sold me on buying one then. Justin was very knowledgeable and helpful without being pushy. Sometimes when you go into these type of places the salespeople can spend all the time trying to push you into buying, when you came in with a clear decision on what you want. Justin respected my decision right off in not buying the most expensive twin bed and frame, although he did spend the time in showing me the more expensive models. Although it was not my intention to purchase the adjustable frame now, the price was unbeatable. I spent months researching adjustable frames and can vouch that the $500 I saved on the frame was a big savings.

Justin greeted us as soon as my wife and I walked into the showroom. We expressed what we were looking for in a mattress and he proceeded to assist with showing us a variety of firm mattresses. He was knowledgeable and very helpful. The entire process was efficient and we left satisfied with our purchase.

The sales staff worked hard to find me a mattress that would support my back (3 spine surgeries). I also was not sure if I wanted a regular box spring or a platform. I ended up with an adjustable base. All came in for what I was looking to pay which was admittedly a low budget. I’m very excited for delivery which I was able to schedule for virtually immediate delivery.

Mattress Firm in South Bay has the best customer service hands down! They help you pick out the best mattress thats made for your body. They don't pick out the most expensive mattress. The drivers are fast and will help you throw out your old mattress.. In 5 minutes everything was delivered and that with clean up. Very, very professional.

Valerie (the store manager( was absolutely amazing in helping me pick out the right mattress. She went above and beyond to help me ensure that the entire transaction went flawlessly. Considering how busy it is the weekend after Black Friday, I truly appreciate the one on one attention she provided me.
