Rated 5 out of 5 by from Peter Van Barneveld is the best salesperson I purchased a mattress on 1/26. Peter was amazing! He took his time, explained everything about differences of mattresses, let me and my daughter try out as many mattresses as we wanted and made sure we would be happy with our purchase. He assured us that if after we purchased the mattress we could change our minds and either return it or exchange it. He stayed open late and let us take the time to make the right decision. We got an amazing price and had the ability to get our mattress the next day! I will definitely buy our mattress from Mattress Firm. Highly recommend. Great product. Great service

Rated 5 out of 5 by from Great Service! I had the best experience with Phil from the West Islip New York store. The day I moved, I realized the mattress that I had been storing in the basement was soaking wet and moldy. I could not sleep on this mattress so I went to Mattress Firm to purchase a new one. Phil was extremely helpful and was able to get me same day delivery so I wouldn't have to sleep on the floor that night. I was very happy with the service, Phil got me in and out in 20 minutes with a great mattress and peace of mind. Thank you!

Rated 5 out of 5 by from The true definition of customer service!!! Peter-- was able to accept the going back and forth between my calls and questions. This is the definition of patience. He explained all the different types of adjustable bases and made sure i wasn't just nodding my head. He knew that this is really important to me, so he wanted to get it right. My father has parkinson's and we want to make his sleep as comfortable as possible. If you are looking to do this PLEASE see Peter Van Barneveld he will point you in the right direction. Thank you again!

Rated 5 out of 5 by from Great Service, Very Knowledgeable My husband and I were in need of a new mattress and had no idea what we were looking for. We went into the West Islip location and was not disappointed. Peter Van Barneveld was so patient and gave us the information that we needed to make the right decision for our needs. We went in there closer to closing, but that did not deter him from making sure we tried everything in the store. I would highly recommend this store!

Rated 5 out of 5 by from Great service I used them a few days ago and I'm pretty happy I did. I first went to the bay shore store but, after waiting for 3-5 mins and didn't see anyone I left. I was going to the mall and saw the west Islip one. Went in and right away Peter introduce himself. He was friendly, well informed, and gave me his undivided attention. Not only did I come away with a new mattress but, a better understanding of them.

Got my mattress for $1299 regularly $1799. Got the adjustable base for $1000. Regularly $1599. after a price adjustment because the adjustable bases are now on sale through 11/27.
