Watch out for

  • The maker says not to leave it in a hot vehicle; heat can warp the grid and may void the warranty.
  • Weight limit: Not stated by the maker.
  • If you add a cushion, check how your seat belt fits. NHTSA says the lap belt should rest across your hips, not your stomach, and the shoulder belt across the middle of your chest, away from your neck. Source: nhtsa.gov (opens in a new tab), checked 6 October 2026. Not professional advice.
