Frequently asked questions about mattresses
Memory foam or hybrid?
Foam isolates motion best and hugs pressure points, which side sleepers and couples liked in our test; it also runs warmest and has the weakest edges. Hybrids (foam or latex over pocketed coils) breathe better, feel bouncier and support heavier bodies. If you sleep hot or over 230 lb, start with a hybrid.
What firmness should I buy?
On the 1–10 scale used here, side sleepers were most comfortable at 5–6.5, back sleepers at 6–7.5, stomach sleepers at 7+. Heavier bodies sink further, so add about a point. Most "medium-firm" mattresses sit at 6–7.
Are the sale prices real?
Bed-in-a-box brands run permanent promotions: the "list" price is rarely paid. We show the maker's current list price, dated, and note in each review what the mattress usually sells for. Judge value on the sale price.
How do you test mattresses?
A queen of each is bought at retail. Two testers sleep on it for seven nights each and log comfort and temperature. We then measure pressure at the shoulder and hip with a mat, surface temperature under a heated pad, motion transfer with an accelerometer and a dropped weight, edge sink under a seated load, and sag after the trial.
