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 4 out of 5 by from Friendly We were greeted right away when we walked in. We knew what mattress were looking for so the salesman directed us to it. We tested it plus a few others & salesman was patient while we hopped on/ off mattresses. Delivery man was on time & courteous, carried in mattress, stopped to cover his shoes when inside and placed in the bedroom. Good price, comfy mattress.

Rated 5 out of 5 by from a pleasure to deal with I had to order a mattress for my guest room and I didn't want to spend a lot of money because the room is harly used. The salesman understood and didn't high pressure me into buying something more expensive than I wanted. He was informative and pleasant. I would definitely go back thre if I needed another mattress or recommend my family and friends to go there.
