Strobel Mattresses use a layer system that has many advantages. 1) No chemical adhesives. 2) If your bed gets wet you can separate and dry out the layers. 3) You can check for mold and mildew. 4) You can clean the inside of your mattress with vacuum and upholstery cleaners. 5) You can move your mattress more easily, even in a car, by rolling up layers and moving separately. 6) You can achieve more even wear and life for your mattress by flipping and rotating the individual layers. 7) If a layer becomes worn you can replace it. 8) You can have a lifetime mattress.
