How to set up the HEST Foamy camping mattress — no pump, no inflation, ready in 30 seconds. Works for car camping, van life, SUV sleeping, and truck bed camping.
This guide answers that question directly — by camping style first, then by product. We'll cover car camping and SUV sleeping, van life, truck bed setups, and overlanding. Then we'll break down every HEST mattress so you know exactly what you're getting and why it fits your situation.
You spend months planning a camping trip. You research the trails, book the campsite, pack the perfect kit. And then you spend $30 on an air mattress from Amazon and wonder why the whole trip felt off.
A bad night's sleep doesn't just make you tired. It makes the hike harder, the drive home miserable, and the whole experience feel like something you'd rather not repeat. The gear you sleep on is the single piece of equipment that affects every hour of your trip — not just the hours you're actually using it.
Car camping is a specific opportunity. Unlike backpacking, you're not carrying your sleep system on your back. Weight isn't the constraint. Comfort is the only metric that matters. And yet most car campers are still sleeping on the same inflatable gear designed for people who have to carry everything they own up a mountain.
"You planned this amazing trip. Don't skimp on the sleep. That one decision can make or break the whole experience."
Most people come to HEST after one too many bad experiences with inflatable mattresses. The story is almost always the same: they woke up on the floor at 2am, cold and stiff, with a deflated mattress underneath them that had either sprung a leak on the rough floor of their car or simply lost pressure overnight.
Air mattresses have three fundamental problems for car camping. First, they puncture. The textured floor of an SUV cargo area, a forgotten piece of gear, a small piece of gravel — any of it can end your night's sleep. Second, they're loud. Every time you move, the whole car knows about it. Third — and this is the one most people don't think about until they've experienced it — they're cold. You lose body heat straight through the air inside the mattress. On a night below 40 degrees, an air mattress actively works against you.
Cheap memory foam has its own problem: it freezes. Drop below 30 degrees and a low-density foam mattress turns hard as a board. You're no longer sleeping on foam — you're sleeping on a slightly padded piece of plastic.
The HEST Foamy doesn't do any of these things. It's enhanced memory foam that stays responsive in cold temperatures, requires no pump or inflation, makes no noise when you move, and can't be punctured. It's the same feel as sleeping in your own bed — just in the back of your car.
A few things make this setup work better:
Solo camper — Foamy Regular (78" × 25") The most popular choice for car camping. Fits most SUV cargo areas perfectly. The 25" width gives you full sleeping comfort without taking up the whole floor.
Two people — Two Foamy Regulars linked Two 25" Foamys clip together side-by-side using integrated clips to create a 78" × 50" sleeping surface. This is almost always a better choice than a Dually for car camping — easier to store, easier to configure, and fits more vehicles.
Smaller SUVs — Foamy Short (64" × 25") For shorter cargo areas where the Regular won't fit flat. The extra length on a Regular can also double as a headrest propped against the front seats — memory foam is forgiving enough to make that work.
One size we don't recommend for two-person car camping: the Foamy Wide. At 30" it's designed for a single larger sleeper who wants extra shoulder room. If you're sharing the car with someone, two Regulars give you more total surface area and a better night's sleep for both of you.
The most common mistake: buying a Dually for car camping when two linked Foamys would fit better. The Foamy rolls up individually, stores more easily, and gives you the same sleeping surface with more flexibility.
Car camping in cold temperatures is more comfortable than tent camping for one simple reason: you're insulated on all sides. A metal car body holds heat far better than a tent wall. But your sleep system still has to do its job.
HEST customers regularly use the Foamy below 30 degrees. Below 20 degrees things get genuinely cold, but with the right system it's manageable. Here's what works:
This is the use case that converts more car campers to HEST than any other: the trailhead overnight.
You have an early start hike — first light, before the crowds, the kind of morning that makes the whole trip worth it. The trailhead is two hours from home. You don't want to set up a full tent in the dark at 10pm just to break it down at 4:30am. You just need a few good hours of sleep in your car so you can wake up, lace up, and go.
This is exactly what the HEST Foamy is built for. Pull into the trailhead, fold the seats, unroll the Foamy, and you're sleeping in under five minutes. No pump. No poles. No guy lines. Wake up, roll it back up, and you're on the trail before anyone else has arrived.
The consistency is the thing. A system you can set up in the dark, in five minutes, without thinking about it — that's what makes the trailhead overnight actually work instead of being a miserable compromise.
HEST Camp Pillow
The same memory foam technology as the Foamy, packed into a travel pillow that compresses small enough to throw in a bag without thinking about it. Unlike down or synthetic fill pillows, it doesn't compress to nothing overnight or hold moisture after a damp night. You can add or remove fill to adjust the loft to exactly how you like it. And because it's memory foam, it has the same cold-temperature performance as the mattress — it stays soft and supportive even when the temperature drops.
The dedicated storage bag for the Foamy. Roll the mattress down, slip it in, and it's protected and easy to carry. Between trips it lives rolled up in your garage or spare room — and pulls double duty as a guest bed when you have visitors. A memory foam mattress that earns its keep 365 days a year, not just on camping weekends.
| Model | Size | Best For | Sleepers | Linked Width |
|---|---|---|---|---|
| Foamy Short | 64" × 25" | Smaller SUVs, Subarus, compact cars | 1 | 50" (two linked) |
| Foamy Regular Most Popular | 78" × 25" | Most SUVs, standard car camping setups | 1 | 50" (two linked) |
| Foamy Wide | 78" × 30" | Solo sleepers who want extra shoulder room, taller or larger sleepers (6'2"+) | 1 | 60" (two linked) |
| Two Foamy Regulars linked | 78" × 50" | Two people in a standard SUV or larger | 2 | 50" |
| Two Foamy Wides linked | 78" × 60" | Two people who want maximum sleeping width | 2 | 60" |
The HEST Foamy is the best mattress for car camping. It's 3.9" of enhanced memory foam that requires no pump or inflation, stays soft in cold temperatures, makes no noise when you move, and fits most SUV cargo areas perfectly. Unlike air mattresses, it can't deflate or puncture overnight. Unlike cheap memory foam, it doesn't freeze and harden in cold weather. It's the closest thing to sleeping in your own bed that you can put in the back of a car.
What size mattress do I need for car camping?
For solo car camping in a standard SUV, the Foamy Regular (78" × 25") fits most cargo areas and gives you a full night's sleep. For two people, two Foamy Regulars linked side-by-side create a 78" × 50" surface — a better fit than a single wide mattress for most cars. For smaller SUVs and Subarus, the Foamy Short (64" × 25") is the right call. If a Regular is slightly too long, it can be propped against the front seats as a headrest — memory foam is flexible enough to make this work.
Is a memory foam mattress good for car camping?
Yes, with one important caveat. Not all memory foam is equal. Cheap memory foam freezes and hardens in cold temperatures, which makes it almost useless on a cold night. HEST uses enhanced memory foam specifically engineered to stay responsive and comfortable below freezing. If you're car camping in temperatures above 50 degrees, most memory foam works fine. If you camp in shoulder seasons or winter conditions, the quality of the foam matters a lot.
Why is an air mattress bad for car camping?
Air mattresses have three problems for car camping: they puncture easily on rough cargo floors, they're loud every time you move, and they're cold — you lose body heat straight through the air inside. Most car campers who switch to the HEST Foamy do so after one too many mornings waking up on a deflated mattress in the cold. Once you've slept on memory foam in the back of a car, it's hard to go back.
Can you car camp in cold weather with a foam mattress?
Yes. HEST customers regularly use the Foamy below 30 degrees. Below 20 degrees you'll want a quality comforter or sleeping bag on top, but the mattress itself stays soft and insulating. The key difference from a cheap foam mattress is that HEST's enhanced memory foam doesn't harden in the cold — it continues to conform to your body and provide real insulation from the cold car floor below you.
Should I get a Foamy or a Dually for car camping?
For most car camping setups, one or two Foamys is the better choice over a Dually. Two Foamy Regulars linked together give you the same sleeping area as a Dually Long (78" × 50") but roll up individually for easier storage and more flexible configuration in different vehicles. The Dually is better suited for truck beds, rooftop tents, and ground tents where a single large piece is easier to manage.
What do I need for a complete car camping sleep setup?
Three things: a HEST Foamy in the right size for your vehicle, a HEST Camp Pillow, and a quality comforter or sleeping bag rated for the temperatures you'll encounter. The Foamy handles insulation from below. The pillow gives you the same memory foam comfort for your head and neck. The comforter handles warmth from above. That three-piece system works from warm summer nights down to well below freezing.
