Barbara was so attentive and caring with all of our concerns. She took her time and gave us all the possible options to help us make the perfect choice! We learned she’s normally at their Rocky Point location, so we were so lucky to have her filling in today in Southampton!
View on GoogleStopped in a couple of weeks ago to get my mother a new mattress. Peter was very patient and helpful as she shopped for the right one, and we felt well taken care of. Today, David delivered her new setup, and both he and his partner were fantastic. Professional, patient, and kind - couldn't have asked for a better experience. I will be back when it's time to replace my bed. Next day edit to say that my mother said she had the best night of sleep in decades. :)
View on GoogleWe had a fantastic experience working with Lauren. She was incredibly knowledgeable, patient, kind and made the entire mattress shopping process easy, fun, and stress free. She took the time to understand what we were looking for; and It was clear that she genuinely wanted to help us find the perfect mattress- not just make a sale. Lauren’s friendly attitude and professionalism truly stood out and we couldn’t be happier with our purchase. Highly recommend asking for Lauren if you’re in the market for a new mattress.
