Every mattress in the table is scored on six weighted criteria, applied identically, using published specifications, verified dimensions and weights, and documented owner experience. No brand-reputation modifiers, no thumb on the scale for the mattress at the top.
Real-mattress feel. Multi-layer foam stacked above the support structure, not stuffed inside an air chamber. No pressure points after a six-hour stretch.
Model-specific cut that handles the seat-fold slope. Built-in floor-flattening is the difference between a flat surface and rolling toward the hatch.
From "stopping" to "horizontal." Integrated pumps beat external. USB-C beats 12V cigarette dependency. And how easy is it to roll back up.
Total weight and packed dimensions. Whether it fits in the sub-trunk or eats half the cargo space. A carry case that protects it through transit.
TPU beats PVC for puncture resistance. Foam certifications. Cover fabric. Warranty length. Protective bottom layers. What owners report after a year.
Price versus what you actually get. A $200 mattress can score 9. A $900 one can still score 7 if it delivers more. Not just "cheapest wins."
The result is a number from 0 to 10, rounded to one decimal place. We do not apply any brand reputation modifier or editor's pick adjustment on top. If a brand we like loses on the math, it loses on the page.
Every mattress in the comparison is assessed on model-specific fit for the Model Y and Model 3 trunk-bed area with the rear seats folded, packed size and weight from manufacturer documentation, pump type and charging requirements, and the setup and pack-down workflow an owner actually faces heading out for a weekend.
Findings are cross-referenced against Trustpilot histories for every brand we cover, plus Reddit threads on r/TeslaModelY, r/TeslaCamping, r/TeslaLounge, and forum discussions on Tesla Motors Club. When sources line up with recurring owner reports, we treat that as confirmation. When they conflict, we dig further before scoring.
No brand pays for placement here. There are currently no affiliate relationships and no commissions of any kind — a score could not be bought even if a brand offered. The Tesla OEM mattress is included purely on its merits, like everything else.
We do not inflate sub-scores to justify a desired ranking. The mattress at the top loses on Value (premium price) and is mid-pack on a few other dimensions. Those losses are why the #1 ranking is defensible.
Six weighted criteria, applied identically to all 13. No brand-reputation modifiers, no thumb on the scale for the mattress at the top.
