My husband and I switched from a pillow top mattress that was very soft to a much firmer foam mattress.  The pillow top mattress made us both roll in to the middle toward each other every night.  It was just way too soft.  The new foam mattress which was much firmer and solved that problem,  although we wanted it to be a little bit softer.  Adding this mattress cover helped to make our bed softer and more comfortable!  And buying from a veteran owned company is the icing on the cake!
