The mattress arrived in a box the size of a mini fridge, so surely it goes back in. It does not, and understanding why saves you a torn mattress and a wasted afternoon.
Why the box was a one way trip
Factory compression uses industrial presses that flatten the mattress evenly under tons of force, then roll and seal it in heavy plastic before the foam can fight back. At home you have body weight and a shop vac, which compress unevenly, and uneven compression is exactly what damages foam cells and voids nearly every mattress warranty, most of which explicitly exclude re compression.
The vacuum bag partial exception
For an all foam mattress being moved, oversized vacuum storage bags can reduce thickness enough to ease a stairwell or a cargo van, with three honest caveats: it will not reach box size, the warranty risk is yours, and hybrid or innerspring mattresses are disqualified entirely, coils bend and stay bent.
How movers actually do it
Flat, in a fitted mattress bag, strapped upright against the van wall. A queen fits most cargo vans and box trucks flat or on its long edge. The mattress bag matters more than any compression scheme: it keeps the mattress dry and clean, which keeps donation eligibility alive at the other end.
The question behind the question
Most re boxing attempts are really returns, storage, or disposal wearing a disguise. Returns: use the retailer’s trial process, they arrange pickup and none require the box back. Storage: flat, bagged, climate controlled, nothing stacked on top. Disposal: skip the origami entirely, a scheduled pickup from $85 takes it exactly as it lies, box not required, donation offered first when it qualifies.
