Jacob was exceptional to work with. Shopping for a new mattress is stressful but he was knowledgeable, kind, patient, helpful, and maybe even most importantly not pushy at all. He helped us resolve a few issues and was responsive. Plus enjoying the new mattress for better sleep!

I thought I thought that shopping for a mattress would be hard and expensive, I went into the store and met Missy and she asked what I was looking for in a mattress, she steered me to what I was looking for and showed me accessories that I’d like. The whole process was quick and within budget. Shopping anywhere else is just throwing money away. I got 5 star treatment from Missy even with my budget. Well done Mattress Firm !

Ed did at great job looking up a previous mattress order and assisting me with ordering the same mattress in a different size with adjustable frame. He was friendly, helpful and efficient. Would recommend Mattress Firm to others based on this experience.

We just bought a split king mattress and adjustable bases. Jacob was extremely knowledgeable and very helpful without being pushy. Delivery was prompt. We’re very happy with our product and service from them!

Michelle was great, she was knowledgeable & very helpful! I have been suffering from back issues. I needed a quick interim firm mattress for now & found one that fit my requirements at a reasonable price.
