Quick answer: For most people dealing with an achy back, the best mattress is a medium-firm one that keeps your spine level without pressing hard into your shoulders and hips. That's the Wright W2.15 Hybrid ($2,155 Queen) if you want the sturdy, responsive feel of a triple-zoned coil base, or the Wright W1.27 ($1,995 Queen) if pressure relief matters more to you than bounce. Both are medium-firm, both are built around the same finding from our sleep research: the balance between comfort and support is what your back actually needs.

Why medium-firm for back pain?

The old advice was to sleep on the firmest bed you could stand. That advice hasn't held up. General sleep guidance today points to medium-firm as the best starting point for most backs, and our own testing landed in the same place.

Here's the logic. Too soft, and your hips sink below your shoulders, bowing your spine all night. Too firm, and the mattress pushes back at your shoulders and hips instead of letting them settle, which forces your lower back to bridge the gap. Medium-firm splits the difference: enough give for your curves, enough support to keep your spine roughly level in every position.

Before we built our first mattress, we ran a two-year sleep study, tracking real testers night after night with Jawbone UP sleep trackers. The pattern that kept showing up was that balance between comfort and support mattered more to deep sleep than any single material or firmness extreme. It paid off in the data: testers averaged 51 more minutes of deep sleep per night on their Wright than on their previous mattress, a list that included Tempur-Pedic, Sleep Number, and Serta. We tuned both of our mattresses to that finding, then refined them through 27 rounds of prototyping for the W1.27 and 15 for the W2.15. The full story is in Inside Wright's R&D.

One honest caveat: we're mattress makers, not doctors. We can tell you what our testing supports about sleep quality and spinal alignment. We can't diagnose or treat back pain, and no mattress can.

What does zoned support actually do?

Your body isn't evenly heavy. Your hips and midsection carry most of the load, your shoulders need room to settle, and your legs barely press into the bed at all. A mattress that pushes back equally everywhere gets that wrong somewhere.

The W2.15's base is 8 inches of triple-zoned, triple heat-tempered pocket coils. The zoning firms up the center third of the bed, where your hips would otherwise sink, and eases off where your shoulders need to settle in. Each coil is pocketed, so it responds to your body independently instead of pulling its neighbors down with it. The result is a spine that stays close to level whether you're on your back or your side.

Which Wright mattress is right for your back?

Choose the W2.15 Hybrid if you want coil support. It feels sturdy and responsive, with a bit of bounce that makes changing positions easy. That matters more than people expect: if your back is stiff, you move around at night, and a bed you can move on beats one you fight with. The zoned coils and reinforced edges also make it the pick for heavier sleepers and for anyone who sits on the edge of the bed to get up.

Choose the W1.27 if pressure relief is your priority. Its 1.5-inch top layer is soft 10 ILD gel memory foam that lets shoulders and hips settle in, over progressively firmer ZeroG layers (18 and 20 ILD) and a 30 ILD base that stops you from sinking too far. You get the cradled, pressure-free feel of memory foam without the hammock effect that soft beds create. In our testing this medium-firm build suited about 90% of sleepers across back, side, and stomach positions.

Not sure which way to go? We broke down every difference in W1.27 vs W2.15. Side sleepers with back trouble should also read our side sleeper guide, since shoulder pressure and back alignment are connected.

How do the Wright mattresses compare on the things that matter?

If you're mattress shopping for your back, the trial length matters as much as the build. Backs take weeks to adjust to a new surface, so a short trial can run out before you know the truth.

Fair is fair: Saatva's 365-night trial and lifetime warranty beat ours on paper, and Tempur-Pedic's deep-conforming foam has decades of loyal fans. Our case is the combination: hotel-grade construction, zoned support, a 120-night trial that's long enough for your back to fully adjust, a 15-year warranty that covers sagging over half an inch with a free replacement, and free in-home installation with old-mattress removal. Details on all of that are in trial, warranty, and delivery explained.

That sagging coverage matters more for backs than people realize. A half-inch body impression quietly turns a supportive bed into a soft one. Most warranties tolerate deeper sag for longer; ours replaces the mattress free.

When should you see a doctor instead?

A mattress is worth trying for the ordinary stuff: waking up stiff, a dull ache that fades as you move, discomfort that started around the time your bed got old. But see a doctor if your back pain is severe or getting worse, follows an injury, wakes you at night regardless of surface, or comes with numbness, tingling, leg weakness, or fever. Those need a professional, not a new bed.

FAQ

Is a firm mattress better for back pain?

Usually not. Very firm mattresses press back at your shoulders and hips instead of letting them settle, which can leave your lower back unsupported. General sleep guidance and our own testing both point to medium-firm as the better starting point for most people.

Should I pick the W2.15 or the W1.27 for my back?

Pick the W2.15 Hybrid if you want sturdy, responsive coil support with zoning that reinforces the hip area. Pick the W1.27 if you want maximum pressure relief at the shoulders and hips with a memory foam feel. Both are medium-firm and both keep your spine aligned.

How long does it take a new mattress to help?

Give it a few weeks. Your body adapts to a new surface gradually, and the mattress itself breaks in over the first month. That's why we give you 120 nights instead of asking you to decide in a showroom.

Does an adjustable base help with back comfort?

Many people find slight elevation of the head or legs takes pressure off the lower back. Both Wright mattresses work on adjustable bases, and we make an Adjustable Bed Frame if you want to pair them.

What if the mattress doesn't help my back?

Return it. The 120-night trial is risk-free: full refund, and we pick the mattress up at our expense, no questions asked.

Give your back 120 nights

Try the W2.15 Hybrid or the W1.27 risk-free for 120 nights, with free shipping and free in-home installation, old mattress hauled away. If your mornings don't improve, we take it back and refund you in full.
