Steps
Start with a firm insulation layer under your body, such as a closed-cell foam mat or camping pad. A soft air mattress alone lets cold air pull heat away.
Add your sleeping bag on top of the pad and check its temperature rating. Choose a bag rated several degrees below the coldest night you expect.
Layer a blanket or quilt over the sleeping bag, not under it. Keep the bedding loose so it traps air and holds its loft.
Fit window covers to the side and rear glass to cut cold drafts and heat loss. Reflective foil or thick fabric works.
Crack one window slightly for ventilation so damp air can escape. This airflow stops condensation from soaking your bedding.
Keep water, your phone, a torch and a warm layer within reach. You want to avoid getting out of bed at night.
Use a hot water bottle or powered bedding only with a safe battery setup. Never run the engine or a fuel heater while you sleep.
Know the limit. If the night will be far below your bag rating, move to a warmer shelter instead of adding more blankets.
Tips and common mistakes
A soft mattress feels cold because air inside it cools quickly, so insulation under you matters more than another blanket on top.
Test your setup at home first and check for cold spots before you rely on it.
Air out your bedding each morning and wipe condensation from the windows to keep it dry.
Never use a camping stove, charcoal burner or unvented gas heater inside the car.
Questions
Why is my car bed cold even with blankets?
Heat escapes downward into the seat and cold air, so you need a foam or closed-cell pad under your body, not just blankets on top.
How do I stop condensation in the car?
Crack a window for airflow, fit window covers, and air out your bedding each morning.
Can I run the car heater overnight?
No. Running the engine while you sleep risks carbon monoxide poisoning. Use insulation and a hot water bottle instead.
