We had an amazing experience working with Cameron at Mattress Firm. He was incredibly knowledgeable and took the time to walk us through all of our options. What really stood out was how patient and thorough he was. He showed us a wide range of mattresses at different price points and helped us truly understand the differences so we could make the best decision for our needs. He was super wonderful to work with, and we highly recommend coming to this store to find your next mattress!

The sales representative (Cameron) was very knowledgeable. He took time to explain the differences between mattresses, and help guide us to our decision. He also knew when to give us space so my wife and I could talk in private as to which mattress we wanted. We were happy with our visit to your store.

I am so impressed with my purchases! I have purchased a mattress in the past and was so pleased that I didn't think twice about using anyone else when I needed another mattress in a different room. I felt super confident in using the company again and would definitely recommend them. Cameron was so helpful, friendly and knowledgeable! He helped me with which mattress would be a good fit for my needs. He answered all my questions promptly and was so patient, professional and polite even through my redundancy. I didn’t originally think a mattress would make such a difference but it has!! I no longer wake up feeling more pain in my back. I can not say enough good things about how pleased I have been with all my purchases. I tell people all the time what a difference having a good mattress has made in my overall well being!! It is definitely a necessity for my spine health!! Thank you Cameron for all your help, it is appreciated!! I am so glad, I finally tried one of the mattress, my only regret was I didn’t do it years earlier and have less pain!!

Cameron was very helpful and knowledgeable without putting too much pressure on us or being pushy. He even stayed open and extra 15 minutes to help complete our sale AND helped strap the mattress to the roof of our car.
