Tom was extremely helpful with helping my mom find a bed that fit her tastes and her budget. He didn’t pressure us or try and sell us the most expensive mattresses but rather listened to understand what was important to my mom. I will definitely return when I need another mattress!

Lee Clark was a very professional and personal salesman. He let us know he was training and had to ask his manager questions about our product! Lee was very patient, and respectful to his trainer and to us! Lee helped us get our purchase in our car as well! Mattress Warehouse has an employee of the month if you need a name!
