Five ways to solve the same night outside. They don't cost the same, and more importantly they don't fail the same way. Here's the whole picture — including the trips where a platform is the wrong buy.
The five options, side by side

The cost that keeps running
Anything on the roof is paid for every day, not just on camping days. On the same road trip our own Tesla used 140 Wh/km with a bare roof and 185 Wh/km with a roof box — 32% more energy, about a quarter of the range. A roof tent is bulkier than a box, so that's the floor. The full measurement and its caveats →
A platform is in the boot on Friday and in the garage on Monday, so it costs nothing to carry.
The honest part
A platform is not the cheapest way to sleep in your car. An air mattress costs $50. But you'll fight it every morning — and then you'll stop going.
That's the real comparison. Not price against price, but how many nights you actually end up spending outside. A platform is the setup you'll still be using in five years.
Flat is not the same as level
Two different problems, and most people only fix one. A mattress bridges the gap over the folded seats, so the surface becomes flat. It does nothing about the slope — almost every boot floor tilts toward the tailgate, and you spend the night sliding downhill in your sleeping bag.
A platform on fixed legs fixes the gap. A platform on adjustable legs fixes both: set the legs once for your car and the bed is genuinely horizontal, every trip after. The full breakdown of gap, slope and fixes →
When a platform is the wrong buy
Four cases where we'd tell you not to:
- You want to try one night and see. Buy a $50 mattress first. If you go out three times in a season, then talk to us.
- You camp in a group and cook outside all evening. A tent gives you a room to stand in. The car is a bedroom, not a living room.
- You need to stand up inside. No car platform gives you that. A van does.
- Your boot is shorter than you are. Some cars simply don't have the length. We'd rather tell you that before you order than after.
Pick by what you're optimising for
- Cheapest possible — mattress in the boot.
- Most space for the money — tent.
- The whole boot completely free while you sleep — roof tent.
- Living in it for months — campervan.
- Regular weekends, and your car has to be a car on Monday — platform.
Next step
Whether a platform works in your car comes down to three measurements. Five minutes with a tape measure and we'll give you a straight answer — including "it won't fit", if that's the truth. We'd rather say no than sell you the wrong thing.
