Securing a Mattress to Your Car

A quality mattress bag or tarp can protect the mattress from weather and road debris, while foam pads can prevent damage to the vehicle’s roof and the mattress itself.

A non-slip mat is also recommended to prevent the mattress from sliding, especially if it’s placed on a smooth surface like a roof rack.

Step-by-Step Guide

Securing a mattress requires careful attention to detail:

  • Position the mattress flat against the vehicle’s roof or in a truck bed, never on its side.
  • Use ratchet straps to tie down the mattress at multiple points, ensuring even tension.
  • Place foam pads between the mattress and the vehicle to prevent damage.
  • Cover the mattress with a tarp or mattress bag to protect it from the elements.
  • Double-check that the mattress is secure and does not obstruct the driver’s view or vehicle signage.
