Tom was extremely helpful, he was very pleasant to work with and very knowledgeable. He helped us decide what was the best for us and didn’t feel like he was pushing for a price tag, he worked with our budget and made us feel like he cared. Thanks Tom! Can’t wait to get this delivered!!

Had a warranty claim for a Purple Mattress that was still under warranty and the salesperson Emad was extremely helpful and knowledgeable. We used most of the credit to buy a Tempur-Pedic mattress that suits our needs. We also purchased a new twin mattress for our disabled daughter. Again, Emad was a pleasure to work with during the transaction. We get our new mattresses tomorrow and we bought them today May 2nd.
