I went back to the store to exchange the mattress I purchased a month ago as it did not suit what I needed. The clerk explained the differences of the mattresses which helped me select a better option. The only problem I encountered was my first 2 choices were not available in the size I needed so I had to choose another. I was told Sealy was not supplying them and orders were not being met and would take 6 months to come in. However, the transaction was fast otherwise with the mattress that is available. I would only suggest that more days should be available for delivery.
