A sore back and a new mattress, without the medical costume

We get this question in the first line of the email. "Which mattress is best for back pain?" The honest answer is that we sell beds, not care, and the question is too big for a product grid.

If the pain is new, severe, shooting down a leg, paired with numbness or weakness, or it followed a fall or an accident, stop reading and talk to someone qualified to examine you. Nothing below is a workaround for that.

What a surface can change

Pressure and position. A bed that lets the hips sink on your back, or that leaves a side sleeper's shoulder on a hard shelf, can make a morning stiffer. Changing that surface can make the morning less stiff. That's a mechanical observation. It is not a cure, and it doesn't tell you why the stiffness started.

The way we'd shop it, if the pain is the familiar kind you've had for a long time and a clinician has already told you it's the ordinary sort:

• Back sleeping, hips sinking: look at Harbor or Loom in the supportive feel. You want the waist in contact and the pelvis held up. The hand test is in the back sleeper note.
• Side sleeping, shoulder and hip taking the night: look at Drift if you want foam, Harbor if you sink too far in foam. The pocket-versus-trench idea is in the side sleeper note.
• Stomach sleeping, low back worse in the morning: stop buying plush. Harbor, thin pillow. The stomach note is blunt about this on purpose.

What we'd want you to track

Seven lines, one each morning. Where it hurt. The position you woke in. Whether it eased after you walked around. If the note is identical every day on a bed that fails a straightedge sag test, the bed is a fair suspect. If the note depends on your work, your shoes, or a week of travel, a new mattress is an expensive guess.

Don't change the pillow, the topper, and the mattress in the same week. You won't know which one did the thing.

The trial is the ethical part of selling this

You should be able to send it back. Thaw's window is 100 nights from delivery. Use it if the mornings get worse, not just different. "Different" for two weeks is common, because you've been living in a sag and the new bed doesn't have your hollow. "Worse" is a return, and you don't owe us a full hundred nights of worse.

We will not publish a percentage of people whose pain "improved." We don't have that study. Anyone who shows you one in an ad without a real citation you can read is selling.

The old bed, in case it isn't the foam's fault

A broken slat feels like a bad mattress. So does a pillow the height of a loaf. So does a protector bunched into a rope under your hip. Fix the cheap variables before you haul a new box upstairs. If you already did, and the sag is visible, replace it. Age is not the test. The replacement essay is.

What we'd put in the cart, and what we wouldn't

If the long-standing pattern is "side sleeper, shoulder and hip, old bed sags," Drift or Harbor, a protector, and a pillow you can change. If the pattern is "back sleeper, soft bed, worse in the morning, eases when I walk," Harbor or supportive Loom. If the pattern is "I don't know, it just hurts," we wouldn't put anything in the cart yet. We'd ask for the seven-line week, and we'd ask whether anyone qualified has looked at it.

We wouldn't add a topper, a new pillow, a cooling cover, and a magnesium recommendation in the same breath. One change. The mattress is the expensive change, so it's reasonable to make the cheap ones first if the bed isn't sagging. If it is sagging, the cheap ones are decoration.

We also wouldn't tell you to sleep on the floor for a month as a cleanse. A night or two, if you want the information, is a personal experiment. It is not a program, and it is not something we'll cheerlead. Take care getting down and up. Then use what you learned: if the floor was better, your bed is probably too soft or too dipped. That's a shopping clue, not a lifestyle.

FAQ

Is a firm mattress better for back pain?

Sometimes, for a stomach sleeper or a back sleeper who sinks. Often worse for a side sleeper. "Firm" is not a prescription. It's a feel, and it isn't even standardized. See firmness.

Can I sleep on the floor instead?

People do, for a night or a week, as a personal experiment. It isn't advice we give, and it isn't a product. If the floor feels better, that tells you something about your current bed's sag. It doesn't tell you to buy the hardest thing in the catalog.

Will you recommend a medical device?

No. We don't sell them and we won't review them as if we did.
