The big name brand mattresses? All single sided. Why? Cheaper to make and will wear out quicker. Good for the factory. Flanagan Mattress has several two sided mattresses which can be flipped. Longer life. And, the price? In many cases less than that one sided name brand. Stop by and see. You be the judge.
Joe Flanagan has been in the furniture and mattress business since 1979. First, as a manufacturer sales representative, and since 1996, as a retail store owner.
