Rated 5 out of 5 by from Riverhead Outlet Store I'm a Beautyrest person so last week I bought a new Beautyrest mattress, no box spring, to replace my 10 year old Beautyrest. It was part of the MattressFirm Labor Day mattress sale so I got a great price for a great new mattress that was just delivered so I'll sleep good tonight. The Riverhead outlet store personnel are very knowledgeable and have a lot of mattresses on display so you can physically see the models advertised in the newspapers which is always a plus. I picked out the delivery date and approximate time and was able to track the truck on the internet. Right on time. I'm very satisfied with all aspects of this purchase.

Rated 5 out of 5 by from Great First Time Experience I was referred here by my co worker. Roger worked with me in getting a queen size mattress and box spring. Roger discounted me the box spring by $150.00 and although my items haven’t been delivered yet, the customer service experience itself with amazing. Roger also offered an earlier delivery time although the box spring had to be changed from the original one I was going to get, but I am still happy with my purchase and didn’t have to break my pockets for good quality. Good experience!!!

Rated 4 out of 5 by from Great Service. Horrible system Great service and very knowledgeable staff. I just bought a house and needed multiple items to purchase. The computer system is beyond antiquated. It took the guy 35 minutes to put all the order in the system. He kept apologizing and he was really nice but the system is painfully slow. Please Upgrade!

Rated 5 out of 5 by from Amazing Experience!! Thank you Roger! I have already recommended multiple people since my purchase on Tuesday with Roger from the riverhead, NY store. I purchased 4 complete bed sets and he made the transaction so simple! I can't thank him enough! If I owned a company I would never want to lose such a dedicated employee as Roger.

Rated 5 out of 5 by from Great experience! My husband and I came in today with a low budget for a mattress for a guest room in our home. Brian greeted us immediately and worked with our low budget. We were able to leave with a mattress that exceeded our expectations. Very happy with our experience. Brian was excellent!
