Is a short full right for you?

Good for

  • Campers, travel trailers and older motorhomes with a 48″ bed or dinette
  • Replacing a factory RV mattress that measures 48 × 74

Watch out for

  • A 48 × 75 “3/4” mattress is 1″ too long. It may hit a wall or cabinet.
  • Rounded or cut corners are common in campers. Measure the corners too.
  • Check the height limit: cabinets and bunks above can limit thickness.
