Questions about beds and mattresses answered. And some stories told.

A hinged mattress is a specially designed mattress commonly used in recreational vehicles (RVs), campers, or trailers. It features one or more built-in hinges that allow the mattress to fold, making it easier to fit into compact or awkward spaces—particularly in slide-outs, Murphy beds, or areas with limited access.

Key Features:

1. Folding Mechanism:

   • Usually splits into two or more sections.

   • Common hinge points are in the middle (like the 70"x45"/35" diagram you provided), allowing one part to fold over the other.

2. Space Efficiency:

   • Makes it easier to move through tight RV doorways or hallways.

   • Ideal for convertible spaces where beds need to be folded away.

3. Comfort and Support:

   • Can be made from memory foam, innerspring, or hybrid materials.

   • Manufacturers typically design them to minimize discomfort from the hinge area.

4. Ease of Installation:

   • Simplifies the process of getting a full-size mattress into a small RV space.

   • Often ships more compactly.

Common Use Cases:

• Murphy beds that fold into the wall.

• Slide-out beds in RV bedrooms.

• Bunk beds or convertible sofas in RVs.
