A good sleeping setup is the difference between a great night in the back of your Subaru and a miserable one. The right pad depends on your cargo floor, how cold it gets, and whether you sleep alone. We chose these for their high ratings and large review counts.

Start With Your Cargo Floor
Fold the rear seats flat, then measure two things: the length from the hatch sill to the folded seat back, and the width between the wheel wells. Our model guides cover how much room each car has: Outback, Forester and Crosstrek. Buy a pad that fits those numbers, not the biggest one.
Pad Types Compared
| Type | Best for | Tradeoff |
|---|---|---|
| Memory foam roll-up | Comfort and simple setup | Bulky to store, heavier |
| Self-inflating pad | Good comfort, packs smaller | Costs more for extra thickness |
| SUV air mattress | Fits around wheel wells in many cars | Needs a pump and can lose air |
| Thin foam pad | Cheapest, lightest | Least comfortable on a hard floor |
Memory Foam Pads
Memory foam is the easiest choice: unroll it and sleep. The roll-up memory foam mattress pad has more than 2,400 reviews at 4.4 stars. If you want something that folds, the MLILY 4-inch tri-fold gel memory foam mattress has more than 4,800 reviews at 4.4 stars. Check each listing’s width against the space between your wheel wells.
Self-Inflating Pads
A self-inflating pad packs smaller than memory foam and adds insulation. The Gear Doctors Oxylus lists an R-value of 4.3, which suits cooler nights, and has more than 4,700 reviews at 4.4 stars.
SUV Air Mattresses
SUV air mattresses are shaped to fill the rear space and fit around the wheel wells on many vehicles. The double-sided flocked SUV air mattress has more than 1,600 reviews at 4.3 stars. Confirm the fit for your exact car and fold the seats flat first.
Staying Warm
A pad that fills the space still needs insulation under you. Look for the R-value, the measure of how well a pad blocks heat loss. Higher is warmer, and cold nights call for a higher number than summer trips. Not every listing states one, so check before you buy. See Sleeping in a Subaru Outback for more on staying warm.
FAQs
What is the best sleeping pad for a Subaru?
It depends on your cargo floor, but a memory foam pad is the simplest and an SUV air mattress fills odd spaces best. Measure first.
Can two people sleep in a Subaru?
It’s tight. See our model guides for how much room each car has.
Do I need a pad if I fold the seats?
Yes. The folded seats leave seams and a hard floor, so a pad helps a lot.
What does R-value mean?
It’s a measure of insulation. A higher number means a warmer pad.
Final Thoughts
Measure the length and the width between the wheel wells, pick a pad that fits, and match the insulation to the weather. A memory foam pad is the easiest first buy.
