We slept on each mattress for weeks in real conditions, judging spinal support, pressure relief, cooling and edge strength by sleeping position rather than a ten-minute showroom test.
The right mattress for back pain keeps your spine aligned without creating new pressure points, and the best choice depends heavily on how you sleep and what your back needs. After sleeping on each of these for weeks, here are the mattresses we would actually recommend to someone waking up sore — from supportive innersprings to pressure-relieving foam.

Supportive, hotel-firm innerspring with a lumbar zone built for spinal alignment.

Zoned coils and memory foam that cushion the shoulders and hips while supporting the spine.

A gel grid that cradles pressure points and stays cool, over supportive coils.

Dense, body-contouring TEMPUR foam that cradles the spine and kills motion transfer.

A supportive hybrid with a plush top that punches well above its price for back support.

A certified-organic latex hybrid that is firm, supportive and breathable for aligned sleep.
Back pain is not one problem. Back and stomach sleepers usually need firmer, more supportive beds that stop the hips sinking; side sleepers need enough give at the shoulder and hip to keep the spine straight. Buy for how you actually sleep, because the wrong firmness for your position can create the pain it was meant to fix.
A good back-pain mattress balances two things: support that keeps the spine neutral, and pressure relief that cushions the shoulders and hips. Innersprings like the Saatva lead on support; grids and foams like Purple and Tempur lead on pressure relief. The best pick gives you enough of both for your body.
No one can tell you which mattress fixes your back from a spec sheet — only weeks of sleep can. Favor mattresses with long, genuine trials and easy returns, like Saatva’s 365 nights, so you can prove it works for your back with no risk. Treat the trial as part of the product.
