It's tough buying a mattress, laying on it ,not your own pillow, shoes on. Strangers in the store, Charlie had such patience and his relaxing manner helped us with mattress selection and all the choices and materials to select from. It is a major purchase and many factors to consider. Our salesman was knowledgeable and helped us with our selection. .

Tara was absolutely AWESOME! We got the mattress we wanted at a great price. Tara went above and beyond to answer all of our questions. She was very knowledgeable and did a great job working within our budget. If you go to Mattress Firm in Sayville make sure you ask for Tara, you'll be glad you did.

Everyone in store was very helpful and kind. However the online shopping not so much! Very misleading online. I now have a headboard for a queen bed I bought and exchanged for a king bed and they don't take back headboards. Never even used it and can't use it now because I now have a King. Delivery was on time quick and efficient. Darin was very helpful with the exchange as well and very much appreciated.
