How to sleep in a car: comfort tips for the passenger seat and rest stops

First rule: the driver doesn't sleep

This guide is for passengers, and for drivers on a real break with the car parked. If the driver feels drowsy, the only fix is to stop somewhere safe and rest, or to swap drivers: opening the window or turning up the music doesn't replace sleep.

Many road-safety organizations also recommend a break about every two hours on long trips. Those stops are the perfect time for the driver's nap.

Set up the passenger seat before you doze off

Car seats keep you upright, which is safer while driving but awkward for sleeping. A few minutes of setup make a big difference:

• Keep the backrest upright while the car is moving: a seatbelt protects you best when you sit normally.
• Rest your head against the headrest and give it support on the side, so it doesn't tip toward the window or the driver.
• Fill the gap on the door or console side with something soft, so your shoulder isn't pressing on hard plastic.
• Support your knees and lower back: a small cushion or a rolled-up hoodie works, a full-body pillow does both.
• Keep your feet on the floor, never on the dashboard, and nothing between you and the airbag.

Pick a pillow that supports more than your neck

A U-shaped neck pillow helps your head, but your shoulders, arms and knees still have nowhere to rest, which is why a neck pillow alone often isn't enough for a real nap in a car.

A full-body pillow that lines the seat, such as the Lulaseat passenger pillow, gives your head, side and knees a soft surface at once, and you still sit and buckle up exactly as usual. Compare the options in our guide to car pillows.

Block out light, noise and temperature swings

Cars are bright, noisy and change temperature fast. A small kit helps you fall asleep and stay asleep:

• Sunglasses or a soft sleep mask.
• Earplugs, or earbuds with a calm playlist or podcast downloaded beforehand.
• A light blanket or an extra layer: the driver usually sets the temperature.
• A water bottle within reach, so you don't have to search for it when you wake up.

Sleeping in a parked car at a rest stop

On long trips, a nap with the car parked is often the best sleep you'll get. Choose a well-lit, busy rest area or a place where parking and resting are allowed: the rules differ from one country, state or town to the next, so check them for where you're going.

• Turn the engine off. Never run the engine to stay warm in an enclosed space or where snow could block the exhaust.
• Open a window slightly for fresh air and less condensation.
• Recline the seat (only now, while parked) and lay your pillow and blanket over it.
• Lock the doors, put up sunshades for privacy, and keep the keys and your phone within reach.
• Set an alarm so a short nap doesn't turn into a long one.

Quick checklist for sleeping in the car

Before a long drive, keep these within reach of the passenger seat:

• A pillow that supports more than your neck.
• A blanket or a hoodie.
• A sleep mask or sunglasses.
• Earplugs or earbuds.
• Water and a snack.
