| Straight Side High Density |
6" High Density Straight Foam Rail System Found on the Bed 4 Life 5500, 4500 and 3500 Airbeds, we designed the straight foam rail system to be a sturdy perimeter to your airbed. The perimeter is responsible for holding the bed together around the air chambers, and also for giving the outside a finished, "squared off" look. Just like the concave rail system, our straight rails are wrapped in a heavy-duty nylon material, and are connected to each other with a full length of the fabric. This greatly increases the stability of your air bed and reduces the wear and tear on the outer cover. |
