Car Camping Mattress for Subaru Crosstrek: Complete Guide to Sleeping in Your Crosstrek

Introduction: The Subaru Crosstrek's Surprisingly Capable Car Camping Potential

The Subaru Crosstrek occupies a unique space in the automotive world as a compact crossover that punches above its weight for outdoor adventure. Built on the same platform as the Impreza but with increased ground clearance, standard all-wheel drive, and a more rugged aesthetic, the Crosstrek has become the vehicle of choice for adventure seekers who need daily drivability combined with weekend capability. And for a growing community of car campers, the Crosstrek's cargo area has proven surprisingly adequate for overnight sleeping.

What makes the Crosstrek particularly appealing for car camping is its balance of capability and efficiency. The standard all-wheel drive system handles unpaved roads to remote camping spots confidently, while the fuel-efficient engine keeps travel costs manageable for extended road trips. The higher ground clearance compared to standard sedans or hatchbacks allows you to reach trailheads and dispersed camping areas that might challenge lower vehicles, opening up camping options beyond established campgrounds.

The Crosstrek's cargo area, while compact, offers enough space for comfortable solo sleeping and workable two-person arrangements for couples who don't mind close quarters. The flat fold-down rear seats create a reasonably level sleeping surface, and the boxy shape of the cargo area maximizes usable volume. This guide covers everything you need to know about selecting the right mattress and creating an optimal sleeping setup in your Crosstrek.

Subaru Crosstrek Cargo Dimensions Across Generations

The Crosstrek has evolved through multiple generations since its introduction in 2012 (sold as the XV Crosstrek until 2015), with subtle changes to cargo dimensions that affect sleeping arrangements. Understanding your specific Crosstrek's measurements ensures you select an appropriately sized mattress and set realistic expectations.

The first-generation Crosstrek (2013-2017) established the basic dimensions that have remained relatively consistent. With the 60/40 split rear seats folded flat, this generation offers approximately 70-72 inches of length from the back of the front seats to the closed rear hatch. The width measures about 40-42 inches at the widest point, narrowing to approximately 38 inches at floor level between the wheel wells.

The second-generation Crosstrek (2018-2023) maintained similar cargo dimensions while refining the vehicle in other areas. The folded seat configuration remained essentially unchanged, with the same approximate length and width. Minor improvements to how the seats fold flat may provide a slightly smoother sleeping surface in these newer models, but the fundamental dimensions remain comparable to the first generation.

The current generation Crosstrek (2024+) brings a new platform with subtle dimension changes. While exterior dimensions have grown slightly, the cargo area remains similar to previous generations. The refined interior design may affect exactly where the folded seat backs meet the cargo floor, potentially improving or altering the sleeping surface characteristics. If you own a 2024+ Crosstrek, verify measurements in your specific vehicle before purchasing a mattress.

All Crosstrek generations share the characteristic Subaru flat-folding seats that create a reasonably level surface. However, there's typically a 1-2 inch step between the folded seat backs and the cargo floor, similar to the Forester and other Subaru vehicles. This transition point requires attention during mattress setup to prevent discomfort.

• First generation (2013-2017): approximately 70-72 inches long, 40-42 inches wide
• Second generation (2018-2023): similar dimensions with refinements
• Third generation (2024+): comparable dimensions on new platform
• Width at floor level: approximately 38 inches between wheel wells
• Height to ceiling: approximately 30-33 inches depending on configuration
• Seat-to-cargo floor transition: typically 1-2 inch step
• All generations feature standard all-wheel drive
• Dimensions accommodate adults up to approximately 6 feet when sleeping diagonally
• Wheel wells intrude at floor level but clear above 3-4 inches height
• Measure your specific vehicle for precise mattress sizing

Creating the Optimal Crosstrek Sleep Setup

Having the right mattress is only part of comfortable Crosstrek camping. How you configure the sleeping area, where you place your gear, and how you prepare the vehicle all significantly impact your sleep quality. These setup strategies help you maximize comfort in the Crosstrek's compact but capable space.

Begin by clearing and preparing the cargo area properly. Remove any cargo mats that might bunch up under your mattress, empty the under-floor storage compartment if your Crosstrek has one, and ensure the area is clean and dry. The weight of your mattress and body will compress anything left in the space, so start with a clean slate.

Fold the rear seats using the release levers located at the top of each seat back. Both the 60 and 40 sections should fold flat for maximum sleeping space. Remove the rear headrests entirely rather than just lowering them, as even lowered headrests create bumps that you'll feel through thinner mattresses. Store the headrests in the front passenger footwell to keep them secure and out of your sleeping area.

Address the transition between folded seat backs and cargo floor, which is one of the most common comfort issues in Crosstrek sleeping. Place a folded blanket, yoga mat, or thin foam pad specifically over this ridge before laying your main mattress. This simple step makes a noticeable difference in comfort by eliminating the pressure point that otherwise falls right around your lower back or hips depending on your sleeping position.

For maximum length, slide the front seats as far forward as comfortable. This gains several inches of sleeping space and can make the difference between comfortable sleeping and feet pressing against the hatch. If you're camping solo, you can also recline the front passenger seat and extend your legs into that space, effectively creating a longer sleeping surface than the cargo area alone provides.

• Clear cargo area completely before setup
• Fold both rear seat sections for maximum space
• Remove rear headrests entirely (don't just lower them)
• Address seat-to-cargo floor transition with blanket or foam
• Slide front seats forward for additional length
• Consider diagonal sleeping for taller campers
• Use front passenger area to extend sleeping space if needed
• Store shoes in front driver footwell
• Keep nighttime essentials within arm's reach
• Install window covers before settling in for the night

Climate Control and Ventilation for Crosstrek Camping

The Crosstrek's conventional (non-hybrid) powertrain means you can't run climate control indefinitely like in a Prius, but proper ventilation and temperature management still ensure comfortable sleeping across a range of conditions. Understanding how to manage the Crosstrek's interior environment is essential for enjoyable car camping.

Ventilation is absolutely mandatory when sleeping in any vehicle. Your breathing produces moisture and CO2 that accumulate in an enclosed space, leading to foggy windows, stuffy air, and uncomfortable sleeping conditions. At minimum, crack two windows on opposite sides of the vehicle to create cross-ventilation. Even in cold weather, this small opening prevents the worst of the moisture buildup while not dramatically affecting interior temperature.

Window rain guards, also called vent visors, are highly recommended for Crosstrek owners who camp frequently. These accessories allow you to leave windows cracked even during rain without water entering the vehicle. They're inexpensive, easy to install, and solve one of the most frustrating aspects of car camping: having to choose between ventilation and weather protection.

In warm weather, focus on maximizing airflow and minimizing heat absorption. Park in shade whenever possible, especially for daytime rests. Use reflective window covers to block solar heat gain. Wait until evening temperatures drop before setting up for sleeping if conditions are hot. A battery-powered fan positioned to move air through the vehicle can make marginal temperatures comfortable and transforms stagnant air into a pleasant breeze.

Cold weather camping in the Crosstrek is more comfortable than many expect because your body heat warms the compact interior noticeably. The space is small enough that one person's body heat raises interior temperatures by 10-15 degrees above outside air. Insulated window covers help retain this warmth, and a sleeping bag rated appropriately for expected temperatures keeps you comfortable. For extreme cold, additional insulation beneath your mattress prevents cold from the cargo floor reaching you.

• Crack at least two windows for cross-ventilation always
• Window rain guards allow ventilation during precipitation
• Battery-powered fans significantly improve warm weather comfort
• Reflective window covers block solar heat and retain warmth
• Park in shade during warm weather
• Body heat noticeably warms the compact interior
• Sleeping bag rating should match expected temperatures
• Add insulation beneath mattress for cold weather camping
• Never run engine in enclosed spaces for heating
• Moisture management prevents condensation problems

Maximizing Crosstrek Utility: Multi-Day Trips and Extended Adventures

The Crosstrek's appeal for car camping extends beyond single nights to multi-day adventures where you're essentially living out of your vehicle. These longer trips require more sophisticated organization and systems to remain comfortable and practical. Here's how to optimize your Crosstrek for extended camping use.

Storage becomes the primary challenge when your cargo area doubles as sleeping space. Everything you bring must either fit in the front passenger area, store efficiently under or around your sleeping setup, or travel on a roof rack. Soft-sided storage bags that can be compressed and wedged into corners work better than rigid containers for maximizing limited space. Keep frequently needed items accessible and less-used gear packed tightly.

Roof racks or roof boxes significantly expand your carrying capacity for extended trips. The Crosstrek's factory crossbars or aftermarket racks support baskets, boxes, or bags that hold gear you don't need every day. This frees up interior space for your sleeping setup and daily essentials. Many Crosstrek campers find that a modest roof box transforms the vehicle from adequate to genuinely practical for week-long or longer adventures.

Develop efficient routines for setting up and tearing down your sleeping configuration. On multi-day trips, you may be setting up every evening and packing up every morning, so a streamlined process saves time and frustration. Know exactly where everything goes, in what order, and build muscle memory through practice. The goal is making setup feel automatic rather than a chore.

Plan for activities outside the vehicle during daytime hours. Unlike larger camper vehicles where you might spend time inside during the day, the Crosstrek is primarily a sleeping solution. Design your days around hiking, exploring, working from coffee shops or libraries, or simply relaxing outdoors. An awning or portable canopy creates protected outdoor space that extends your living area beyond the vehicle's small interior.

• Roof storage dramatically expands multi-day trip capacity
• Soft storage bags flex to fit available spaces
• Develop efficient, repeatable setup and teardown routines
• Plan activities outside the vehicle during daytime
• Keep frequently used items accessible, pack other items tightly
• Awnings or canopies create outdoor living space
• Know overnight parking options for extended travel routes
• Regular organization maintenance prevents gear chaos
• Food storage requires planning given limited space
• Water and power management become priorities on longer trips

Frequently Asked Questions

Can I sleep comfortably in a Subaru Crosstrek?

Yes, with appropriate setup and realistic expectations. Solo campers under about 6 feet tall can sleep comfortably in the standard cargo area configuration. Taller individuals need to sleep diagonally or extend into the front passenger area. The space is comparable to a small backpacking tent: not luxurious, but perfectly adequate for overnight adventures when properly equipped.

What size mattress fits in a Subaru Crosstrek?

A mattress approximately 70 inches long and 40 inches wide fits the Crosstrek cargo area well. Cot-sized mattresses (25x72 inches) fit easily between the wheel wells with room to spare. Wider mattresses will work but may press against the wheel well areas at floor level. Crosstrek-specific mattresses are designed to fit the unique cargo shape and generally provide the best fit.

How does Crosstrek camping compare to the Forester?

The Forester is larger in all dimensions, offering approximately 4-6 inches more length and width for sleeping, plus more headroom. This makes the Forester better for taller individuals and couples. The Crosstrek compensates with better fuel efficiency, easier parking, and a lower price point. Solo campers under 6 feet often find the Crosstrek adequate, while couples generally prefer the Forester's additional space.

Can two people sleep in a Crosstrek?

Two people can sleep in a Crosstrek, though it's intimate. The approximately 40-inch width provides only 20 inches per person, narrower than most beds. Couples who sleep closely find it manageable for occasional trips. Those who prefer space or move around during sleep may struggle. For regular two-person camping, consider the larger Forester or Outback, or embrace the cozy arrangement.

How do I deal with the gap between seats and cargo floor?

This 1-2 inch step is a common comfort issue in Crosstrek sleeping. Address it by placing a folded blanket, yoga mat, or thin foam pad specifically over the transition zone before laying your main mattress. This creates a more level surface and prevents the ridge from pressing into your body during sleep. Some owners create custom-cut foam inserts for a permanent solution.

Is the Crosstrek good for winter car camping?

The Crosstrek works well for winter camping with proper preparation. Your body heat warms the compact interior significantly, and insulated window covers help retain warmth. You need a sleeping bag rated for expected temperatures, extra insulation beneath your mattress to block cold from the floor, and appropriate bedding layers. Without running the engine, people regularly camp in Crosstreks below freezing with proper gear.

Should I build a sleeping platform in my Crosstrek?

Platforms can work but significantly reduce the already limited headroom. Even a 4-inch platform noticeably impacts your ability to sit up or move around. For most Crosstrek campers, addressing the seat-to-cargo transition with foam or blankets provides most of the benefits without the height penalty. If you need under-bed storage, consider low-profile solutions that minimize height impact.

What's the best way to cover Crosstrek windows for privacy?

Several options work well: custom-fit window covers designed for the Crosstrek, cut-to-fit reflective sunshade material, or fabric curtains attached with suction cups or magnets. Custom-fit options provide the best convenience and appearance but cost more. DIY reflective insulation provides excellent privacy and temperature control at minimal cost. Cover all windows including the sunroof if equipped.

Will car camping damage my Crosstrek's interior?

With reasonable precautions, no. Use a moisture barrier beneath your mattress to protect the carpet from condensation and body moisture. Ensure proper ventilation to prevent mold and mildew. Avoid eating in the sleeping area. Remove your setup periodically to clean and inspect. Many owners camp in their Crosstreks regularly for years without interior issues.

What essential gear do I need beyond a mattress?

Essential additions include: sleeping bag or bedding appropriate for temperatures, pillow, window covers for privacy and insulation, and a ventilation solution like rain guards or cracked windows. Highly recommended: battery-powered fan, LED interior lights, water bottle, small trash bag, and organizing solutions. Many campers also add an awning or canopy for outdoor living space and keep a dedicated car camping kit ready to go.

How tall can you be to sleep in a Crosstrek?

With the standard sleeping orientation (head toward front, feet toward rear), campers up to about 5 feet 10 inches can sleep comfortably. Taller campers can sleep diagonally, which adds several inches of effective length, or extend their legs into the reclined front passenger area. At 6 feet 2 inches or taller, you'll likely need creative solutions or may find the Crosstrek impractically small for regular sleeping.
