Apparently Labor Day sales are some of the best year round! Jacob was great! Informative, listened to what I was looking for, and helped me find it easily. Let me test out of other types of beds and he knew enough about the different mattresses to help narrow down my search.

Bill was fantastic!! He was very helpful and answered all our questions. He gave us time to try different mattresses and talk it over. We ended up purchasing the one he recommended. It is getting delivered in a couple days and we’re excited to get some good sleep on our new mattress. We would definitely buy here again.

Big shout out to Jacob for making our mattress shopping experience easy and efficient! When we decided to go out shopping for a new mattress, we thought we would be stopping at a few stores and then making a decision. We went into Mattress Firm and we were greeted quickly by Jacob asking us if we wanted help right away or if we wanted to look around first. His courteousness allowed for us to peruse first and then ask for his expertise. We didn’t have to go to any other store! He sold us on a mattress right away! What a great employee! We were shopping for a mattress for my college aged son, and when we left the store, my son said, “that was a great guy and this was so fast”! You definitely built a couple of new lifetime customers with this sale! Bravo!

Jim at Mattress Firm provided us with the information we were looking for, showed us mattresses that met our needs, and he was very personable with no pressure to buy anything. We ran out of time, but we'll be going back this week to finalize a purchase.
