What Features Should You Consider When Choosing a Mattress for Your Subaru Outback?
When choosing a mattress for your Subaru Outback, several features are essential to ensure comfort and fit.
- Size: The mattress should be appropriately sized to fit the dimensions of the rear cargo area of your Outback.
- Material: Different materials like memory foam, air, or inflatable options each provide distinct comfort and support levels.
- Portability: A mattress that is lightweight and easy to store or transport will enhance its usability for camping or road trips.
- Durability: The mattress should be made of high-quality materials that can withstand wear and tear, especially if used outdoors.
- Thickness: An optimal thickness is crucial for comfort; too thin may not provide enough support, while too thick may not fit well.
- Water Resistance: Choosing a mattress with water-resistant properties can protect it from moisture, especially in outdoor settings.
- Ease of Setup: The mattress should be easy to inflate or set up, allowing for quick transitions from driving to sleeping.
Size: It is vital to measure the cargo space of your Subaru Outback to ensure the mattress fits snugly without excessive gaps. A mattress that is too large can be cumbersome, while one that is too small will not provide adequate sleeping surface.
Material: Memory foam offers great support and comfort, contouring to your body, while air mattresses can provide adjustable firmness levels. Consider your personal preferences and how you plan to use the mattress when selecting the material.
Portability: A mattress that can be easily rolled up or packed away is essential for maximizing space in your Outback. Lightweight options are preferable for ease of handling, especially when setting up camp.
Durability: Look for mattresses that are made from robust materials, as they will be subjected to various conditions, including temperature changes and moisture. A durable mattress will last longer and provide better value over time.
Thickness: An ideal thickness typically ranges between 3 to 6 inches, depending on your comfort needs and the depth of the cargo area. A thicker mattress can offer more comfort but may compromise space, so balance is key.
Water Resistance: Water-resistant materials help prevent damage from spills or condensation, making your mattress more suitable for outdoor adventures. This feature is particularly important if you plan to sleep in unpredictable weather conditions.
Ease of Setup: Quick setup features like built-in pumps or self-inflating designs can save time and hassle, allowing you to transition smoothly from driving to sleeping without extensive preparation. Look for features that align with your travel style and frequency of use.
How Do You Measure the Space for a Mattress in a Subaru Outback?
To measure the space for a mattress in a Subaru Outback, you need to consider several factors related to the vehicle’s interior dimensions and layout.
- Rear Cargo Area Dimensions: Measure the width, length, and height of the rear cargo area when the back seats are folded down.
- Seat Configuration: Determine the configuration of the rear seats, as some models may have adjustable or removable seats that can affect space.
- Mattress Thickness: Consider the thickness of the mattress you intend to use, ensuring it fits comfortably without obstructing visibility or impeding the closing of the hatch.
- Preferred Mattress Type: Decide on the type of mattress you want (e.g., inflatable, foam, or custom) as each has different space requirements and flexibility.
- Additional Gear Considerations: Account for any additional gear or belongings you may want to transport alongside the mattress for a camping trip or road trip.
The rear cargo area dimensions can vary slightly between model years, but typically, you will want to measure the width from the inside of one side panel to the other, the length from the back of the front seats to the rear hatch, and the height from the floor to the top of the cargo area.
The seat configuration plays a crucial role; if the seats are permanently fixed, it will limit the space available for the mattress. However, if the seats can be folded flat or removed, you may gain additional length and width for a more comfortable fit.
The thickness of the mattress is important, as it should not be so thick that it interferes with the closing of the hatch or block your line of sight while driving. A thinner mattress may provide more headroom, making it easier to move around inside the vehicle.
When choosing a mattress type, inflatable mattresses are often preferred for their compactness and ease of storage, whereas foam mattresses may offer better comfort. Make sure to check the dimensions of the chosen mattress type to ensure compatibility with your measured space.
Finally, consider any additional gear you’ll be bringing along, as this may influence the size of the mattress you can comfortably fit. If you’re planning to camp, you might need to prioritize space for sleeping gear, which could affect the dimensions of the mattress you select.
What Are the Best Materials for Comfort and Durability in Subaru Outback Mattresses?
The best materials for comfort and durability in Subaru Outback mattresses include memory foam, latex, and high-density polyurethane foam.
- Memory Foam: This material is known for its excellent contouring properties which provide superior comfort by conforming to the body’s shape. Memory foam also offers great support, helping to relieve pressure points, making it ideal for long car trips or camping.
- Latex: Natural latex is highly durable and resilient, providing both comfort and support without compromising on longevity. Its breathability helps regulate temperature, ensuring that the mattress remains comfortable in various weather conditions, which is particularly beneficial for outdoor adventures.
- High-Density Polyurethane Foam: This type of foam is recognized for its sturdiness and ability to maintain structure over time, providing a supportive sleeping surface. It typically offers a good balance between firmness and comfort, making it a practical option for Subaru Outback mattresses that need to withstand varying weights and conditions.
- Inflatable Air Mattresses: While not a foam, air mattresses can provide adjustable comfort levels and are often lightweight and easy to store. They can be less durable than foam options, but high-quality models offer good support and can be a comfortable choice for short trips.
- Hybrid Mattresses: Combining materials such as foam and innerspring, hybrid mattresses can offer the best of both worlds—support and comfort. They tend to provide better airflow than traditional memory foam, making them a good choice for temperature regulation during camping or road trips.

Prepare the Cargo Area: Before installing the mattress, remove all personal items from the cargo space and fold down the rear seats. This will provide a flat, even surface for your mattress, enhancing comfort during use.
Use a Mattress Protector: To keep your mattress clean and extend its lifespan, a waterproof mattress protector is highly recommended. This will shield the mattress from spills, moisture, and dirt, making it easier to maintain.
Secure the Mattress: To ensure safety while driving, it’s important to secure the mattress so it doesn’t shift or move around. You can use straps or bungee cords to anchor it down, especially if you plan to transport it for extended periods.
Consider Air Mattresses: An inflatable air mattress can be a great alternative to a traditional mattress, as it can be deflated for easy storage when not in use. Many air mattresses are designed to fit snugly in vehicles and can provide a comfortable sleeping surface while maximizing space in your Outback.
