Ex and Wilmer gave me a warm and polite greeting as soon as I walked into the store, which made a great first impression. After I explained to Ex what I was looking for in a mattress, he immediately began guiding me through the options that best suited my needs and stayed within my budget. He was knowledgeable, patient, and made the entire process smooth and stress-free. Wilmer also checked in to ensure everything was going well, which I appreciated. I would definitely recommend this store to a friend who is also looking to purchase a new mattress soon.

I went in earlier this week and put a deposit down on a mattress to reserve at sale price. In person they were super nice. Ended up changing my mind as the mattress was realistically a little out of budget as a collage student. Called and got my refund in literally 2 minutes, no questions or hassle at all. Wouldn't hesitate to come back in a few years when I am ready to buy a more long term mattress.

We had a great experience at Mattress Firm today thanks to Wilmer. He was friendly, knowledgeable, and patient while helping us choose the perfect Sealy mattress. He made the whole process easy and stress-free, and we never felt rushed or pressured. Highly recommend working with Wilmer if you’re looking for great service and a smooth buying experience!
