Will a Full-Size Mattress Fit in the Back of a 4Runner

Yes, a full-size mattress can fit in the back of a Toyota 4Runner, but it depends on your seating configuration and mattress dimensions. The 4Runner cargo area offers roughly 47.2 cubic feet of space with the rear seats folded, which is enough for a standard full-size mattress measuring 54 inches wide by 75 inches long. You will need to remove the rear seats or fold them flat to make it work comfortably.

Key Takeaways

• A full-size mattress fits in a 4Runner when the rear seats are folded or removed, but measuring your specific model year is essential.
• The 4Runner cargo area is about 47.2 cubic feet with the rear seats down, giving enough room for most mattress sizes.
• Removing the rear seats provides the most flexibility and ensures a proper fit without damaging the seats or mattress.
• A queen-size mattress may be tight in some 4Runner models, so a full-size mattress is the safer choice for most owners.
• Use a cargo net or tie-down straps to secure the mattress during transport and prevent shifting on the road.
• Consider the 4Runner tailgate height when loading and unloading a heavy mattress to avoid back strain.
• Offroad camping trips benefit from this setup, as the 4Runner is a capable vehicle for outdoor adventures.

Will a Full-Size Mattress Fit in the Back of a 4Runner?

If you have ever tried to move a mattress in or out of a truck, you know it is not always easy. The Toyota 4Runner is a popular SUV known for its rugged build and generous cargo space. But can you actually fit a full-size mattress in the back of one? The short answer is yes. The longer answer depends on a few factors we will walk through in this guide.

Whether you are moving to a new home, going on a camping trip, or just need to transport a mattress for a friend, knowing your 4Runner’s cargo limits matters. A full-size mattress measures 54 inches wide and 75 inches long. The 4Runner cargo area can accommodate this, but you need the right seating setup and a bit of planning. Let us break down everything you need to know.

The 4Runner has been a trusted vehicle for decades. Its boxy shape gives it more cargo room than many modern SUVs. This makes it a great option for hauling large items like mattresses, furniture, and camping gear. That said, every model year and trim level has slight differences in interior dimensions. So let us look at the numbers more closely.

4Runner Cargo Space Dimensions

Understanding the cargo dimensions of the 4Runner is the first step. The rear cargo area behind the last row of seats is where your mattress will go. With all rear seats up, the space is quite limited. But with the seats folded or removed, the picture changes completely.

Rear Cargo Area With Seats Folded

When you fold down the rear seats in a 4Runner, the cargo floor becomes one flat surface. The approximate dimensions are:

• Length: About 73 to 77 inches depending on model year
• Width: About 50 to 54 inches between the wheel wells
• Height: About 18 to 22 inches from the cargo floor to the roofline
• Volume: Roughly 47.2 cubic feet

A full-size mattress is 54 inches wide and 75 inches long. The length fits well within the 4Runner cargo area. The width is right at the edge, which means you may need to let the mattress rest on the seat cushions or adjust it slightly. This is where things get a little tricky but still very doable.

Rear Cargo Area With Seats Removed

If you remove the rear seats entirely, you gain a few extra inches of width and a much flatter floor. The 4Runner rear seats are not glued in, so they can be taken out with basic tools. This is the best option if you plan to haul a mattress regularly. Removing the seats also gives you more vertical clearance, which helps when loading and unloading.

Here is a quick comparison of the two setups:

• Seats folded flat: Good for occasional mattress hauling. Width may be tight for a full-size mattress.
• Seats removed: Best option. More width, more length, and easier loading and unloading.

Full-Size Mattress Dimensions Explained

A standard full-size mattress, also called a double mattress, measures 54 inches wide by 75 inches long. It is a popular size because it fits two adults comfortably. It is also smaller than a queen or king mattress, which makes it more manageable for vehicle transport.

Here are the key dimensions to remember:

• Width: 54 inches (4.5 feet)
• Length: 75 inches (6.25 feet)
• Thickness: Typically 10 to 14 inches for innerspring and memory foam models

The thickness of the mattress matters too. A thick pillow-top mattress might not fit comfortably under the 4Runner roofline with the seats up. But with the seats folded or removed, even a thicker mattress should fit. Keep in mind that the cargo area height is limited, so a very bulky mattress may require you to let part of it rest on the rear seats even when folded.

How to Fit a Full-Size Mattress in Your 4Runner

Now that you know the dimensions work, let us talk about how to actually get the mattress in and secured properly. Following the right steps makes the process much easier and safer.

Step 1: Prepare the Cargo Area

Start by clearing out the rear cargo area. Remove any spare tires, cargo covers, or bulky items that take up space. If your 4Runner has a cargo net or cargo management system, you may want to temporarily remove it to give yourself more room to work.

Step 2: Fold or Remove the Rear Seats

For most 4Runner models, you can fold the rear seats down using the pull straps located on the left side of the cargo area. Pull the strap, and the seatbacks fold forward. If you want more room, remove the rear seats entirely. You will need a 10mm or 12mm wrench to remove the bolts at the base of each seat.

Pro tip: Take a photo of the seat mounting area before removing the bolts. This makes reinstallation much easier later.

Step 3: Load the Mattress

Have a helper help you with this step. A full-size mattress is heavy and awkward to handle alone. Slide the mattress into the cargo area lengthwise, with the long side aligned along the cargo floor. If the width is tight, you can let one side of the mattress rest on the folded seat cushion area.

Do not force the mattress into a position where it is bent or folded. This can damage the mattress core and reduce its lifespan. If it is a very tight fit, try rotating the mattress 90 degrees to see if the width fits better.

Step 4: Secure the Mattress

Securing the mattress is critical for safe driving. A loose mattress can shift during turns and braking, which is dangerous. Use ratchet tie-down straps or bungee cords to anchor the mattress to the cargo tie-down points in the 4Runner floor. Wrap the straps around the mattress and tighten them until the mattress does not move at all.

A cargo net can also help keep the mattress in place. If you frequently haul large items, investing in a quality cargo net or cargo management system is a smart move.

Common Mistakes When Hauling a Mattress

Even with the right setup, people make mistakes that can damage the mattress, the vehicle, or both. Here are some common errors to avoid:

• Forcing the mattress through the rear door: The 4Runner rear hatch is not very tall. Do not try to slide a mattress through the hatch. Always load it through the cargo area from the inside.
• Leaving the mattress exposed to the elements: If you are driving with the tailgate open, use a waterproof mattress cover. Rain and dirt can ruin a mattress quickly.
• Overloading the vehicle: The 4Runner has a payload capacity of around 1,000 to 1,500 pounds depending on the trim. A full-size mattress weighs 50 to 100 pounds, so this is usually not an issue. But add other cargo and you should check the total weight.
• Not checking tire pressure: Heavier loads can affect handling. Make sure your tires are properly inflated before a long trip.
• Ignoring local laws: Some areas have rules about how cargo should be secured and whether it can extend beyond the vehicle. Check your local regulations.

Expert Tips for 4Runner Owners

After helping many 4Runner owners with cargo challenges, here are some expert tips that make a real difference:

• Use a moving blanket: Place a moving blanket under the mattress to protect the cargo floor from dirt and scratches. It also prevents the mattress from sliding around.
• Check the tailgate latch: A heavy mattress in the back can put extra pressure on the tailgate. Make sure the latch is secure before driving.
• Consider a roof rack: If you need to carry a mattress on the roof, a roof rack with crossbars can work. But this is not ideal for long trips or highway driving due to wind resistance.
• Plan your route: Avoid rough roads if possible when hauling a mattress. Offroad driving can shift the mattress and damage it.
• Keep the rear window cracked: This helps with airflow and reduces wind noise when driving with the tailgate open.

How the 4Runner Compares to Other Toyota Models

The 4Runner is not the only Toyota vehicle that can carry a mattress. Let us compare it to a couple of other popular Toyota models to give you perspective.

Vehicle	Cargo Length (Seats Down)	Cargo Width	Fits Full-Size Mattress?
Toyota 4Runner	~73-77 inches	~50-54 inches	Yes (seats folded or removed)
Toyota Tacoma	~60-65 inches (bed)	~50-55 inches (bed)	Full-size fits with overhang
Toyota Camry	~36 inches (trunk)	~40 inches (trunk)	No
Toyota Sienna	~83 inches (seats removed)	~52 inches	Yes (seats removed)

As you can see, the 4Runner holds its own when it comes to hauling large items. The Toyota Tacoma pickup truck has a slightly longer bed, but the width is similar. The Toyota Camry is too small for a full-size mattress. The Toyota Sienna minivan offers more length when seats are removed, which makes it a strong competitor for hauling bulky items.

If you are curious about what adults can fit in the back of a Tacoma, check out this guide on seating capacity in the Tacoma. It gives useful insights that apply to both trucks and SUVs.

For those who want to maximize space in a Toyota Sienna, removing the second row seats in a 2025 Toyota Sienna is another great option for hauling large items like mattresses and furniture.

Can You Use the 4Runner for Offroad Camping With a Mattress?

The 4Runner is one of the most popular vehicles for offroad camping trips. Its rugged build, 4WD capability, and generous cargo space make it ideal for outdoor adventures. Bringing a full-size mattress on a camping trip can turn a rough night into a comfortable sleep under the stars.

Here is how to set up your 4Runner for a camping trip with a mattress:

1. Remove the rear seats to create a flat sleeping platform.
2. Place the mattress on top of a moving blanket or foam pad for cushioning.
3. Add a sleeping bag and pillows on top of the mattress.
4. Use a cargo cover to keep everything secure during offroad driving.
5. Store gear around the mattress in the remaining cargo space.

Many 4Runner owners also use rooftop tents or truck bed tents for sleeping. But having a full-size mattress inside the vehicle gives you a more comfortable and weatherproof option. It also keeps you off the ground, which is helpful in areas with insects, moisture, or uneven terrain.

If you are new to offroad camping, this guide on sleeping in a Rav4 Hybrid has helpful tips that apply to the 4Runner as well. Both vehicles offer similar cargo setups for outdoor sleeping arrangements.

Is It Better to Buy a Smaller Mattress Instead?

While a full-size mattress fits in the 4Runner, you might wonder if a smaller mattress would be easier to work with. A twin or twin XL mattress is significantly smaller and much easier to fit in any vehicle. A twin mattress is 38 inches wide and 75 inches long. It fits comfortably in the 4Runner even with the rear seats up.

However, a twin mattress is only 38 inches wide, which is too narrow for two adults. If you need a mattress for two people, a full-size mattress is the best compromise. It is wide enough for two sleepers and still fits in the 4Runner with the right setup.

A queen mattress is 60 inches wide and 80 inches long. It will not fit in the 4Runner with the seats folded, and it is very tight even with the seats removed. If you need a queen-size mattress, consider renting a larger vehicle or using a roof cargo carrier designed for oversized items.

Final Thoughts

So, will a full-size mattress fit in the back of a 4Runner? Absolutely yes. The 4Runner cargo area is spacious enough to handle a full-size mattress when the rear seats are folded or removed. Just remember to measure your specific model year, secure the mattress properly, and take your time loading and unloading.

The 4Runner is one of the most capable SUVs for hauling large items. Its boxy design and generous interior dimensions make it a great choice for moving, camping, and hauling gear. Whether you are a weekend warrior or someone who regularly needs to transport large items, the 4Runner delivers.

Now that you know the mattress fits, plan your next move with confidence. Gather your tools, grab a helper, and get that mattress loaded safely. Your 4Runner is up to the task.

Frequently Asked Questions

Can a queen-size mattress fit in a 4Runner?

A queen-size mattress may fit with the rear seats removed, but it will be a very tight squeeze. The queen is 60 inches wide, which exceeds the 4Runner cargo width of about 50 to 54 inches. A full-size mattress is the safer choice for the 4Runner.

Do I need to remove the rear seats to fit a full-size mattress?

You can fit a full-size mattress with the rear seats folded down, but removing the seats gives you more room and makes loading and unloading much easier. Removing the seats is recommended if you plan to haul a mattress frequently.

How much does a full-size mattress weigh?

A standard full-size mattress typically weighs between 50 and 100 pounds depending on the material and type. Innerspring mattresses tend to be heavier, while memory foam and latex mattresses are usually lighter.

Can I fit a full-size mattress in a 4Runner with a cargo cover installed?
