Had the best experience. I am not the easiest customer, but Noah and Ronald were amazing to work with. Knowledgable, and very accommodating. Can’t say enough about the 2 of them. They are a big reason I bought a mattress today. I would recommend them to anyone searching for a new mattress
View on GoogleToday I bought a Beautyrest Mattress &Tempur-Ergo adjustable frame from your Commack office. I was assisted by Simon who was so friendly, knowledgeable, very experienced & professional. He answered all of my questions as well as information about both items that I wouldn’t have even thought of to ask . I feel confident in my purchase and recommend this store and especially Simon to anyone looking to buy a new bed.
View on GoogleDiana P at the Commack location was a pleasure to meet with. She met us with smile, kept us in budget, didn’t waste our time, was knowledgeable, sociable, and very patient with our requests. I would absolutely recommend her to anyone looking to purchase a new mattress, and I believe she is an excellent example of the exact employee you’d want on the floor.
View on GoogleDiana at the Mattress Firm in Commack was absolutely fantastic. She is incredibly knowledgeable about all the different mattresses and took the time to walk me through everything so I could make the right decision. I probably drove her a little crazy with all my questions and going back and forth between different mattresses, but she was patient the entire time and never made me feel rushed. She genuinely wanted to make sure I ended up with the mattress that was right for me. Her professionalism, patience, and knowledge is very appreciated. I highly recommend Diana to anyone shopping for a mattress. I’ll definitely be recommending her to my friends and family. She truly goes above and beyond to help you find the perfect fit.
View on GoogleAntony was my salesperson. Very knowledgeable of all the different kinds of mattresses and asked questions of me to determine price point and kind of mattress would best suit me. Inner spring, Temperpedic, Hybrid etc. He made the experience easy and even enjoyable!
