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

Went there with a mattress in mind that we wanted, but open minded enough to check out other mattresses. We were helped by Brian who not only knew his products but was respectful about what we wanted and what we were willing to spend. Brian was able to answer every question we had from the differences in brands, the types of mattresses down to the type of sheets that work best. I appreciate being able to go in, find what we want without the high pressure salesman tactics. The next time we need a mattress or other furniture, we'll be going back there and working with Brian.Read More

Excellent customer service at Mancini's!! A Romanian man at the counter was helpful over the phone and in store when I decided to run in to buy a mattress pallet. He was very helpful, in no rush, and even helped me attach the bulky pallet to the top of my car with twine so it wouldn't fall off. Highly recommend!!Read More

Purchased a new mattress earlier this week and was very pleased with the experience. Ron assisted me and was both friendly and professional. I was able to chose the day for delivery. I received a call the evening before and was given a 2 hr. opening. On delivery date, I received a call advising that the truck was on it's way and sure enough it pulled up right on time. The new mattress was brought in and set up, the old one removed and taken away all in about 5 minutes total. Couldn't have been easier.Read More
