Can Full Size Mattress Fit In SUV? Practical Answers Before You Drive

If you’re wondering “Can full size mattress fit in SUV?”, you’re likely planning a move or pickup and hoping to skip delivery. The answer is: sometimes yes, sometimes no—it depends on both the SUV and the mattress type. This guide walks you through what to measure, what to expect, and safer alternatives to forcing a mattress into a too-small space.

What Are the Dimensions of a Full Size Mattress?

Before asking whether a full size mattress can fit in an SUV, it helps to know what you’re working with.

A standard full (double) mattress is typically around:

  • Width: 54 inches (about 4.5 feet)
  • Length: 75 inches (about 6.25 feet)
  • Thickness: usually 8–14 inches, depending on the model

These measurements can vary slightly by manufacturer, so check your specific mattress size if possible.

Why it matters: an SUV’s cargo space is measured in both length and height, and the rigid shape of many mattresses means you’ll need room not just for the footprint, but also for the thickness and any necessary bending or angling.

Can Full Size Mattress Fit In SUV in Most Cases?

In many cases, a full size mattress may fit in a larger SUV, but it is not guaranteed. It usually depends on:

  • The interior cargo length with rear seats folded flat
  • The height and width of the cargo opening
  • Whether the mattress is foam, hybrid, or innerspring
  • How comfortable you are with bending or slightly compressing the mattress

Larger, boxy SUVs are more likely to handle a full size mattress lying flat with the seats folded. Smaller or compact SUVs might require the mattress to be angled, bent, or partially sticking out (which raises safety and legality concerns).

Key Measurements to Check in Your SUV

To see if a full size mattress can fit in SUV, measure these three areas:

  1. Cargo length

    • With the rear seats folded down, measure from the back of the front seats to the inside of the rear hatch.
    • You’re aiming for at least 75 inches for a full mattress to lie mostly flat.

  2. Cargo width

    • Measure the narrowest point across the cargo area, often between wheel wells.
    • You’ll want at least 54 inches of width or the ability to angle the mattress.

  3. Cargo opening height and width

    • Measure the rear hatch opening. Even if the interior is large enough, a small opening can prevent the mattress from going in.

📝 Quick check:
If your SUV’s cargo length is under 70 inches, or the narrowest width is under 50 inches, fitting a full mattress flat inside will be difficult without angling or bending it.

Does Mattress Type Affect Whether It Fits?

Yes. Whether a full size mattress can fit in SUV also depends on how flexible the mattress is.

Memory foam or all-foam mattresses

  • Generally more flexible and compressible
  • Often can be gently folded or bent for short trips
  • Easier to maneuver through smaller cargo openings

Hybrid or innerspring mattresses

  • Contain coils or springs that are stiffer and less flexible
  • Bending too much may damage the internal structure
  • Often need to be transported more flat and supported

If you’re unsure how much you can bend your mattress, it’s usually safer to avoid folding it sharply or forcing it into tight corners.

Can You Transport a Full Mattress Partially Bent or Angled?

Sometimes people manage to fit a full size mattress in an SUV by:

  • Angling it diagonally from one rear corner to the opposite front seat
  • Leaning it slightly upright with the rear seats folded
  • Gently bending foam mattresses to follow the contour of the cabin

When doing this:

  • Avoid severe folds, especially with innerspring or hybrid models.
  • Do not compress the mattress so tightly that it creases sharply.
  • Make sure it is secure and doesn’t obstruct visibility or move freely while driving.

Is It Safe to Drive With a Mattress Sticking Out?

If the mattress does not quite fit fully inside, some people consider leaving the hatch partially open.

Things to consider:

  • This can affect visibility and safety.
  • Local rules may require tying down and clearly marking any load that sticks out.
  • Exhaust fumes and weather exposure can be concerns if the hatch is not closed.

From a practical standpoint, if a full size mattress can’t fit in SUV with the hatch fully closed and the mattress reasonably secure, it may be better to consider a different vehicle or delivery method.

✔️ Quick Mattress Takeaways

Key points to know about “Can Full Size Mattress Fit In SUV?”

  • Full mattress size: About 54" x 75", plus thickness.
  • Large SUVs: More likely to fit a full mattress flat with seats down, especially if cargo length is close to or above 75".
  • Compact SUVs: May require angling or gentle bending; fitting fully flat is less likely.
  • Foam mattresses: Usually more flexible and easier to fit into tight spaces.
  • Innerspring/hybrid mattresses:Stiffer and less suitable for bending; need more room.
  • Always measure: Check your SUV’s cargo length, width, and hatch opening before attempting transport.
  • If the mattress must stick out or be severely bent, it may not be a practical or safe fit.

When Is an SUV Not the Best Choice?

An SUV may not be ideal for a full mattress if:

  • Your measurements show significantly less than 75 inches of usable length.
  • The cargo opening is too narrow or low to get the mattress inside.
  • You have a thick, rigid innerspring or hybrid mattress that doesn’t bend easily.

In those cases, a pickup truck, van, or mattress delivery service often leads to less stress and a lower risk of damaging the mattress.

With a tape measure, a bit of planning, and an honest look at your vehicle’s space, you can decide confidently whether a full size mattress can fit in SUV or if another option makes more sense for your move.
