Will a Mattress Fit in a Subaru Outback?
Enter your mattress size — the app checks Outback cargo length (35–75" with seats up/down), width (44"), and loading options.
Whether it fits depends on measurements most people get wrong.
Key Measurement
Outback cargo length (75") matches twin mattress length (75") exactly
Standard Dimensions
Item: Twin: 38" × 75". Full: 54" × 75". Queen: 60" × 80". King: 76" × 80"
Space: Outback cargo (seats folded): 75" L × 44" W × 33" H. Volume: 75.7 cu ft. Seats up: 35" L, 32.5 cu ft
Actual clear openings are usually 1–2″ smaller than the labeled size.
Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.

What to Measure
- 1Outback cargo length with seats folded (75") — the longest in its class, nearly matching a twin mattress (75") without any angling needed
- 2Outback cargo width (44") vs. mattress width — identical to the RAV4; a twin (38") fits flat while a full (54") exceeds the floor width by 10"
- 3Wagon-style liftgate opening — the Outback's wide liftgate opening (approximately 43" wide × 32" tall) is easier to load through than typical compact SUVs
- 4Flat cargo floor design — the Outback rear seats fold to create one of the flattest cargo floors in its class, ideal for sleeping on a mattress during road trips
Common Mistakes to Avoid
- Confusing the Outback with the Forester — the Outback has 75" of seats-folded cargo length vs. the Forester's 70", making a significant difference for mattress fit
- Assuming a queen mattress fits because the Outback has 75.7 cu ft — cubic feet does not equal flat floor area; the 44" width blocks a 60" queen
- Not folding both rear seat sections — the 60/40 split allows partial folding, but you need both sides flat for a mattress
- Forgetting that the Outback's lower roofline limits vertical space — at 33" of cargo height, thick pillow-top mattresses leave less headroom than taller SUVs
Frequently Asked Questions
Will a twin mattress fit in a Subaru Outback?
Yes — a twin mattress (38" × 75") fits in the Outback with rear seats folded. The 38" width fits within the 44" cargo width, and the 75" length matches the 75" cargo floor exactly. This is one of the best compact SUV fits for a twin mattress.
Can I fit a full mattress in an Outback?
A full mattress (54" × 75") is 10" wider than the Outback cargo floor (44"). It can sit above the wheel wells with overhang, creating a tight fit. The 75" length matches the cargo floor perfectly. A foam full folded in half (27" × 75") fits without any width issues.
Can I sleep on a mattress in my Outback?
Yes — the Outback is a popular car-camping vehicle. With seats folded, the 75" × 44" flat floor fits a twin mattress perfectly. The 33" cargo height provides enough room to lie flat but not sit up. Many owners use a twin foam mattress or sleeping pad for road trips.
Is the Outback better than the RAV4 for mattress transport?
Yes — the Outback has 75" of cargo length (seats folded) vs. the RAV4's 73", and 75.7 cu ft max cargo vs. 69.8 cu ft. Both have 44" of cargo width. The Outback's wagon-style body provides a flatter, more accessible cargo floor.
