We recently purchased our 2nd mattress from the Mattress Factory in Exton and we are extremely happy and satisfied with our purchase. Just as we were a few years ago when we purchased a mattress for our child’s room. In this case, we were upgrading our Queen sized bed to a King. The manager of the store, Jerry Polansky, was extremely helpful throughout the process and he answered all of our questions. We never felt pressured to make the purchase and we even ended up coming back the following day after we couldn’t decide between a few of the models. This store offers all of the top brands and from what I have experienced, they have the best prices and customer service in the area. We also had no problems with the delivery. We will definitely go back when it times to upgrade mattresses for our other bedrooms.
