View on GoogleWe had a wonderful experience working with the store manager, Miguel. He took time to learn what we wanted and what we did and want in a mattress. He showed us several different options and helped us talk through each one to see if that was the best fit for us. It's such a big decision, and a lot of money. So I appreciate somebody helping us make the best choice for us.
View on GoogleIt was an absolute delight working with Miguel! He addressed our questions thoroughly. He approached us conservatively and respectfully, contrary to the cheesy, tacky typical salesperson ways. I appreciated his honest, authentic intentions. He added value to our overall experience and made it for a very pleasant one!
