Can I Fit a Full Size Mattress in an SUV? Practical FAQ Guide

If you’re asking “Can I fit a full size mattress in an SUV?”, you’re usually trying to avoid delivery fees or a truck rental. The short answer: sometimes yes, sometimes no—it depends on both the SUV’s cargo space and the type of mattress you’re moving.

This FAQ walks through what matters, how to measure correctly, and what to watch for so you can decide safely and realistically.

What Are the Dimensions of a Full Size Mattress?

A full size mattress (also called a double) is typically:

• Width: 54 inches
• Length: 75 inches
• Thickness: Usually 8–14 inches, depending on the model

For transport, the most important dimensions are 54" x 75". Your SUV needs to accommodate this either:

• Laying flat, or
• At a slight angle, with enough room to close the doors safely.

Can I Fit a Full Size Mattress in an SUV in General?

Many people can fit a full size mattress in an SUV, but it is not guaranteed. It depends on:

• Interior cargo length with seats folded
• Rear opening size (height and width of the tailgate opening)
• Whether the mattress is flexible (foam) or more rigid (some hybrids, innerspring)

As a rough guideline:

• Compact SUVs: Often struggle to fit a full mattress flat; you may need to angle it or leave the hatch slightly open (which is not always safe or allowed).
• Midsize SUVs: Frequently can fit a full mattress with the rear seats down, sometimes at a slight diagonal.
• Large SUVs: More likely to fit a full mattress flat or with minimal angling.

The best approach is to measure your SUV before you attempt it.

How Do I Measure My SUV to Know for Sure?

To answer “Can I fit a full size mattress in an SUV?” for your specific vehicle, grab a tape measure and check:

1. Cargo Length (with seats down)

   • Measure from the inside of the closed rear hatch to:
     • The back of the front seats (in the position you plan to sit while driving), or
     • The dashboard if you’ll slide the passenger seat forward and down.
   • You ideally want at least 75 inches of usable length, or slightly less if you can angle the mattress.

2. Cargo Width

   • Measure between the narrowest points, often between wheel wells.
   • You need close to 54 inches of width, but you might get away with a bit less if the mattress can curve slightly at the edges.

3. Rear Door Opening

   • Measure the height and width of the tailgate opening at its narrowest point.
   • If the mattress can’t pass through this opening, it doesn’t matter how big the interior is.

A simple reference:

Does Mattress Type Affect Whether It Will Fit?

Yes. Mattress flexibility can make a big difference.

Foam or Flexible Mattresses

• Often easier to bend or curve slightly to fit into tight spaces.
• Some foam mattresses can be rolled or compressed for transport (especially if they originally came compressed in a box).
• Always follow any manufacturer guidelines on folding; some recommend avoiding tight bends for long periods.

Innerspring or Hybrid Mattresses

• Tend to be stiffer and less willing to bend.
• Forcing a fold can damage internal components.
• These usually need more straight, open length inside the SUV.

Key takeaway: A full size foam mattress is more likely to fit in an SUV than a rigid, traditional innerspring.

Is It Safe to Transport a Full Mattress on Its Side or Bent?

In an SUV, you may need to angle or stand the mattress on its side.

• On its side: Often fine for short trips. The mattress may shift, so it needs to be secured with straps or ropes.
• Slightly bent/curved: Common with foam mattresses in smaller SUVs. Avoid extreme folds, especially with innerspring or hybrid designs.
• Tightly folded in half: Can be risky for some mattresses and may affect comfort or structure.

If you’re unsure, it’s safer to avoid sharp bends and aim for a gentle curve or flat position.

What’s the Best Way to Load a Full Mattress Into an SUV?

Once you know your SUV can fit the mattress, a simple approach helps:

• Use a mattress bag or cover to keep it clean.
• Fold or lower rear seats completely for maximum space.
• Load through the rear hatch, not the side doors.
• Angle the mattress in through the opening, then straighten it as much as space allows.
• Secure it with straps, bungee cords, or rope to prevent sliding forward during braking.

🚩 Avoid driving with the tailgate partially open unless you can secure the mattress safely and are comfortable with the risks (exhaust fumes, weather, and potential legal restrictions).

✔️ Quick Mattress Takeaways

Key points to understand about “Can I fit a full size mattress in an SUV?”

• A full size mattress is about 54" x 75", and your SUV must roughly match that space.
• Whether it fits depends on SUV size, cargo length with seats down, and rear opening dimensions.
• Foam mattresses are usually easier to maneuver and bend slightly than innerspring or hybrid models.
• Always measure your SUV (length, width, and hatch opening) before transport to avoid surprises.
• Transport on its side or at a slight angle is usually fine if the mattress is secured and not sharply folded.
• Keeping the mattress protected, stable, and within the vehicle generally offers a safer, cleaner move.

With a tape measure and a few quick checks, you can confidently decide whether your full size mattress and your SUV are a good match for the trip.
