Chad was super helpful to my husband and I as we purchased our new mattress. We came in and went through their bed match process and then he talked us through each of the options and expanded based on our experience in the store. Delivery options made for a super quick turnaround (1 day!). We’d recommend Chad and Mattress Warehouse to anyone!

We worked with Jim George and what a delight! From the moment I walked into the door Jim was unbelievably welcoming, but more importantly he was attentive to our needs, he listened intently and he educated us extensively on mattresses and what would be the perfect fit for us. We had to purchase four mattresses! He’s a straight shooter too and very transparent which gained our trust in him very quickly. I would HIGHLY recommend working with Jim for all your mattress needs. His witty personality made our experience equally as fun too! Thank you a million times over Jim!

Jim has been amazing. He sold us a great mattress, pillows and the whole process was seamless. We highly recommend going to this store and asking for Jim. Jim also fixed the mattress remote control TWO different times when I dropped it and it fell apart. Go see Him at Mattress Warehouse of Harbour Square in Rehoboth Beach. He is the man!

Jim George is an outstanding sales manager! Excellent experience. My second time here because my prior experience working with Jim was just as great. Love my mattresses too. Great products.

Went in to get what I thought was what I needed - basic box springs; then I met Jim. Lucky I did because that man knows all about beds- mattresses; support fames; everything. He was so friendly & knowledgeable. He took the time to really listen to me and explained options I didn’t know existed. In the end I avoided repeating my prior mistakes and even saved money! What is usually a chore and a big pain was actually a very pleasant experience! I highly recommend Jim & would give him 10 stars ⭐️!
