Great service! We had already been in before to browse, but hadn't made a decision. Bob helped my husband and I try out several, answering all our questions and guiding us to what we liked the best. We returned to make a decision and Katie was great! She let us look without pressure and despite the store being very busy, she helped us wrap up our purchase and financing very quickly! I can't wait until my mattress arrives!

Even tho it was a little busy when we went in, we were greeted. We had time to look around at mattresses ourselves before someone was available. Only had to wait about 5 minutes. Katie was very helpful and friendly! We were in and out with the mattress scheduled to deliver in only 2 days! Highly recommend!

Katie made our mattress buying experience much easier than expected. She is knowledgeable, friendly and did not “sell” us but helped us make informed decisions. Thanks Katie!

Danielle was awesome! She made our first experience buying a mattress really easy and stress-free. She didn't try to push a sale onto us, she listened to what we wanted and suggested the perfect one for us.

This by far was one of my best experiences with making such a major purchase on my new mattress and frame. Danielle was knowledgeable, professional ,patient and took her time to explain all the details of my purchase. I ended up buying The best mattress and frame without having to compromise, comfort and pricing. And The delivery service was just as great of an experience. I would definitely recommend this location to anyone looking for a new mattress, frame and the accessories.
