Working with Ike was such a pleasure. He took his time and was patient with my husband and I while picking the best mattress for us. Ike was also wonderful at keeping the price at what we could afford comfortably. I will recommend to family and friends. We will definitely be back to get extras for our new bed!
View on GoogleThe staff was exceptionally informative and allowed us to lay on the mattress and use the remote to experiment with the various positions available on the mattress. Both fun and informative at the same time, our sales person was great not only in knowing how the bed worked but also had patience to take time with his customer. Excellent staff to work with and we will recommend them highly!
View on GoogleI couldn’t recommend anywhere else to get a mattress. They were absolutely amazing, they cared about all my needs and answered all my questions. The best costumer service I’ve had in a very long time! The prices were very friendly and they had just about anything you asked for.
View on GoogleWe found the staff and customer service to be well educated and courteous. Very helpful without being pushy. Always happy to answer any and all questions with patience. In a world where buying options are endless it’s rare to find a place that still values the customer as more than a sale.
