Rated 5 out of 5 by from Couldn’t have wished for a better experience I walked in this store hoping to get an idea of what I wanted and walked out with a brand new mattress at a great price. The money I spent may seem insignificant, but to me it’s my hard earned money. Our salesperson Tahir Naveed should make employee of the month, no joke. He was like the salesperson you wish you could have straight out of a commercial. Super professional and smart and he worked with us to get us the best mattress we could afford. He also knows what he’s talking about. He spent 2 hours with us and genuinely wanted to help, especially since my husband has a bad back. He even lugged a mattress from one platform to another to show us the one we liked on another frame. I recommend this location, and especially this salesperson, highly.

Rated 5 out of 5 by from Great service-excellent salesperson Went in to buy a mattress and Scott, the manager from Commack/Smithtown, was unbelievable! What a patient, caring and professional man. He helped me find the perfect mattress. I have a bad back and he was very patient and helpful in picking out the right one for me. What a true professional. His knowledge and professionalism helped seal the deal for me. If you are ever in need of a mattress, do not go anywhere else but the Smithtown location. Ask for Scott he's great!

Rated 5 out of 5 by from Quick easy and painless! Steve did a great job helping us to find the perfect mattress today. A couple with bad backs at the age of 26 can be tough customers, but Steve made sure to break down the support of each mattress for us. Thanks Steve!
