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.
"Comfort is the thing you don't notice when it's right — and can't stop noticing when it's wrong. A truck bed mattress is the one piece of gear that affects every single hour of your trip."
Car camping is where HEST started and where the lineup performs best. The typical setup: fold down the rear seats of an SUV, hatchback, or crossover to create a flat cargo floor, then lay your mattress across the full length of the cargo area.
The two things that matter most for car camping are fit and setup speed. You're often rolling into camp after dark, tired from a drive, and you want to be horizontal in under a minute. HEST's pure foam mattresses — the Foamy and Dually — deliver that. Unsnap two buckles, let it unroll, and you're done. No pump, no waiting for inflation, no waking up in the night because the mattress has gone soft.
For solo car campers, the Foamy Wide (30" × 78") is the best choice in most SUVs. It's wide enough to give you room to move and long enough for anyone under 6'6". For couples sharing a cargo area, the Dually in Long or Wide format fits most mid-size and full-size SUVs.
Memory foam is the right material for van life. Air mattresses and self-inflating pads fail over time — valves wear out, seams separate, and you end up replacing them every season. HEST foam doesn't have valves or air chambers to fail. The Foamy has been tested to last 5–10+ years with normal use.
Three HEST mattresses work well for van life:
HEST foam handles all three well. The high R-value (8.8 on the Foamy) insulates you from the cold metal floor — this matters more in a truck bed than almost any other camping context because you're directly on metal, not ground. Wheel wells can be worked around with the right sizing: the Foamy Regular (25" × 78") fits between most wheel wells in mid-size and full-size trucks. The Wide (30") will rest on top of the wheel wells in most trucks, which some people prefer for the extra width.
For couples in a truck bed, the Dually Short (50" × 64") or Dually Long (50" × 78") fits most 5–6 foot truck beds. Rivian R1T and R1S owners have dedicated vehicle-specific options (see below).
Overlanding pushes gear harder than any other type of vehicle camping. You might camp at sea level Monday and at 10,000 feet Thursday. Temperatures swing 40 degrees between day and night. Gear gets compressed, thrown around, and used daily for weeks at a stretch.
The biggest risk with air mattresses in overlanding is temperature-driven deflation. Air contracts in cold — a mattress inflated at 70°F can lose 10–15% of its volume by the time temps drop to 40°F overnight. At altitude, the effect is more pronounced. You wake up on a half-flat mattress on a cold metal floor, which is a miserable start to a day of trail driving.
HEST foam doesn't deflate. The Foamy and Dually are 100% solid foam — what you put down is what you wake up on, regardless of elevation or overnight temperature. The foam formulation is also specifically engineered to resist cold-weather stiffening, so it doesn't turn into a board when temps drop below freezing.
For overlanding, the HEST Foamy Wide is the most practical choice — it packs reasonably small, sets up instantly, and performs across the temperature ranges most overlanders encounter. The Sleep System is the upgrade if you're building out a more permanent rig and want maximum comfort at base camp.
Best for: solo campers, car campers, van lifers, overlanders, and anyone who wants the fastest possible setup.

The Foamy is HEST's most versatile and most popular mattress. It uses two layers of enhanced memory foam — a soft, body-cradling top layer and a denser, more supportive base — housed in a zippered, water-resistant cover. Unsnap two buckles and it unrolls and expands in about 30 seconds. No pump, no inflation, no fuss.
The R-value of 8.8 is among the highest in the camping mattress category, meaning the Foamy performs well in genuine cold weather — HEST has tested it to -14°F. The New York Times Wirecutter named it the best camping mattress they'd tested for comfort.
It comes in three sizes: Short (25" × 64"), Regular (25" × 78"), and Wide (30" × 78"). Most people doing solo car camping or SUV camping choose the Wide for the extra room. Two Foamys can be linked side by side using the included clips for a couple's setup.
Best for: solo car campers, truck bed sleepers, van lifers, SUV campers, four-season use, anyone who hates fussing with pumps or inflation.
Choosing the right Foamy size comes down to your height, sleeping style, and available space:
Best for: couples, truck bed campers, rooftop tent users, and anyone who needs a two-person solution.

The Dually is HEST's dedicated two-person mattress. It uses the same enhanced memory foam technology as the Foamy but in a wider, flatter format designed for fixed sleeping platforms — truck beds, rooftop tent floors, and large tent footprints. Field & Stream called it the best camping pad they'd ever slept on.
It comes in four sizes: Short (50" × 64"), Long (50" × 78"), Wide (60" × 72"), and Queen (60" × 78"). The Queen size gives you near-standard queen bed dimensions in the field.
One thing worth noting: unlike two linked Foamys, the Dually doesn't allow each person to adjust firmness independently. If one partner likes a softer feel and the other prefers firmer, two Foamys with side clips is the better call.
Best for: couples camping in truck beds, rooftop tents, or large tents; anyone who wants a queen-size sleeping surface; campers with dogs who share their sleep space.
Best for: campers who want maximum comfort and the closest thing to a home mattress in the outdoors.

The Sleep System is HEST's flagship product and the most comfortable camping mattress in the lineup. It pairs a temperature-resilient memory foam sleeping surface with a supportive, outdoor-rated inflatable drop-stitch base. The result is a mattress that's both extremely comfortable and structurally stable — it doesn't sag in the middle or shift around the way pure air mattresses do.
At up to 7 inches total thickness, the Sleep System sits meaningfully higher off the ground than the Foamy. If you have back pain, sleep hot, or simply find thinner camping mattresses uncomfortable, this is the one. It also comes with HEST's memory foam camp pillow, so you're getting a complete sleep kit in one package.
Clever Hiker called the Sleep System "the most comfortable and durable camping mattress we've tested." It's designed for tent camping, van life, station wagon camping, truck conversions, rooftop tents, and ground sleeping.
Best for: campers who prioritize maximum comfort above all else; people with back pain; car campers who want the closest thing to their home bed; long-haul van lifers and full-time overlanders.
HEST has partnered with Rivian to produce two custom-cut mattresses built to the exact dimensions of Rivian cargo areas.
Designed to fit the Rivian R1S cargo area with precision. If you own an R1S and use it for camping or overlanding, this is the cleanest possible sleeping solution — no trimming, no fitting, no improvising.
The same idea, custom-cut for the Rivian R2. The R2's cargo dimensions differ from the R1S, so this is not the same product. If you're an R2 owner, this is your version.
Both vehicle-specific Foamys use the same dual-layer memory foam and water-resistant materials as the standard Foamy lineup. The only difference is the custom shape.
Here's how every HEST mattress stacks up across the factors that matter most:
| Mattress | Sleepers | Construction | R-Value | Setup | Best Use Case |
|---|---|---|---|---|---|
| Foamy (Short / Regular / Wide) | 1 | Pure memory foam | 8.8 | 30 sec, no pump | Solo car camping, van life, SUV, truck bed |
| Dually (Short / Long / Wide / Queen) | 2 | Multi-layer foam | High | 30 sec, no pump | Couples, truck beds, rooftop tents, large tents |
| Sleep System | 1–2 | Foam + inflatable base | High | Requires inflation | Max comfort, back pain, long-term van life |
| Foamy for R1S | 1–2 | Pure memory foam | 8.8 | 30 sec, no pump | Rivian R1S owners |
| Foamy for R2 | 1–2 | Pure memory foam | 8.8 | 30 sec, no pump | Rivian R2 owners |
R-value measures thermal resistance — how well a mattress insulates you from the cold ground beneath you. Higher is warmer. Here's a practical guide:
What makes HEST's cold-weather performance meaningful beyond the number is the foam formulation. Most memory foam — including the kind in your home mattress — becomes noticeably stiffer in cold temperatures. HEST uses a proprietary temperature-resilient foam that maintains softness and flexibility even at freezing temperatures. This has been tested down to -14°F.
Air mattresses, by contrast, lose 10–15% of their volume when temperatures drop from 70°F to 40°F because air contracts with cold. HEST foam doesn't deflate because it contains no air chambers. What you inflate to at camp is what you wake up on — every time.
What is the best mattress for van life (Not a Sprinter van)?
For full-time van life, the HEST Sleep System is the best choice — its hybrid foam-plus-inflatable base delivers up to 7 inches of comfort for nightly long-term use. The HEST Foamy Wide is the better option if you roll and stow your mattress regularly to reclaim cargo space during the day. Both handle the temperature swings (hot deserts, cold mountains) common in van life without deflating or stiffening.
Does HEST make a mattress specifically for Sprinter vans?
Yes. The HEST Dually Custom is purpose-built for Mercedes Sprinter vans, custom-cut to the Sprinter's interior dimensions for a seamless fit with no gaps or overhang. It uses the same multi-layer memory foam as the standard Dually — durable enough for full-time van life, insulating enough for cold-weather camping, and comfortable enough for nightly long-term use. If you're running a Sprinter build, this is the mattress to get.
What camping mattress works best for truck bed sleeping?
The HEST Foamy Regular (25" × 78") fits between the wheel wells of most mid-size and full-size truck beds. The Foamy Wide (30") rests on top of the wheel wells for extra sleeping width. For couples in a truck bed, the HEST DuallyShort (50" × 64") or Long (50" × 78") is the purpose-built option. Rivian R1S owners have a custom-cut Foamy for R1S designed to fit precisely.
What is the best camping mattress for overlanding?
The HEST Foamy Wide is the best overlanding mattress for most setups. It cannot deflate (no air chambers to lose pressure at elevation or overnight temperature swings), uses temperature-resilient foam that stays soft below freezing, has an R-value of 8.8, and sets up in 30 seconds. The HEST Sleep System is the upgrade for overlanders building a permanent rig who want maximum comfort at base camp.
What is the best HEST mattress for solo camping?
The HEST Foamy Wide is the best all-around choice for solo camping. It offers 30" of width, an R-value of 8.8, a 30-second setup with no pump required, and performs in all four seasons. The Regular size is fine if you're taller than average and space is tight; the Wide gives you more room to move if you're a restless sleeper.
Which HEST mattress is best for couples?
The HEST Dually is the purpose-built two-person option — available in four sizes up to a full Queen (60" × 78"). If each partner wants to control their own firmness independently, two HEST Foamys linked with the included side clips is the better setup. The clips hold them securely together so they don't separate during the night.
What is the difference between the Foamy and the Sleep System?
The Foamy is a pure foam mattress — unroll, done. The Sleep System is a hybrid: memory foam sleeping surface on top of an inflatable drop-stitch air base. The Sleep System is thicker (up to 7 inches versus ~3.9 for the Foamy), requires inflation, and delivers an even more home-like feel. It also includes a matching memory foam pillow. Choose the Foamy if portability and simplicity matter. Choose the Sleep System if maximum comfort is the priority.
Can HEST mattresses be used in cold weather?
Yes — all HEST mattresses are designed for cold-weather use. The Foamy has been tested to -14°F and uses temperature-resilient foam that stays soft even in freezing conditions. Unlike air mattresses that lose volume as temperatures drop, HEST foam maintains its thickness and insulation value throughout the night.
Do HEST mattresses deflate overnight?
No. The Foamy and Dually are 100% solid foam — there is no air to lose. You cannot deflate them. The Sleep System has an inflatable base, but the foam sleeping surface above it does not change thickness regardless of what happens to the base. This is one of the key advantages of HEST over air-only and hybrid air mattresses.
Does HEST make a mattress for the Rivian R1S?
Yes. HEST makes the Foamy for R1S, which is custom-cut to fit the R1S cargo area precisely. HEST also makes the Foamy for R2 for Rivian R2 owners. Both use the same dual-layer memory foam as the standard Foamy lineup.
How long do HEST mattresses last?
HEST mattresses are built to last 5–10+ years with proper care, and are backed by a 5-year warranty. The covers are machine washable. The foam is housed in a durable, water-resistant case designed for outdoor use in all conditions.
Is the HEST Foamy worth it compared to a cheaper air mattress?
For car camping, yes — by a wide margin. A $300 mattress used 20 nights per year costs $15 per night in year one and $3 per night in year five. Air mattresses require pumps, are susceptible to punctures and overnight deflation, and provide poor insulation (R-values of 1–5 are typical). HEST foam requires no setup equipment, cannot deflate, and has an R-value of 8.8. For weight-conscious backpackers, ultralight air pads are still the better choice — but for anyone sleeping in or near a vehicle, HEST wins on every dimension except upfront price.
