Customer Talk on Sleepworld Design
Our Customers Love Us And We Love Them!
John listened to my need and cost and looked at my choice of mattress. I loved how he did not try to sell me another mattress. No pressure! John answered all my questions and arranged to have my mattress delivered on Monday-it's Saturday.Read More

Myyyy goodness! My husband and I laid on about ten mattresses and swapped back and forth between two of them many many times. At no point did we feel pressured to hurry up and make a decision! The customer service was incredible and Brandon made sure that we were getting what we wanted and understood the differences between each mattress! I highly recommend anyone not sure of what they want or 100% sure of what they want to go to Mancini's Sleepworld in Concord!!!Read More
