This is the question that brings most people to this category. The answer is genuinely encouraging and genuinely limited, and the limits are the part usually left out.

The short answer
UT Southwestern Medical Center states that using a standing desk properly might help relieve back pain caused by excessive sitting, and cites a 2018 study in which sit-stand desk users experienced a 50 percent decrease in low back pain compared with controls. The same source is clear that a standing desk will not correct serious structural problems such as scoliosis or a bulging disc. This is not medical advice — see a clinician about your own back.
Back pain is the one outcome in this category with a genuinely encouraging finding behind it. A 50 percent decrease against controls is a large effect, and UT Southwestern — a major academic medical center, not a desk retailer — is the one reporting it.
Hold that alongside the broader picture. The 2018 Cochrane systematic review found only low-quality evidence that sit-stand desks reduce sitting at all, and none about longer-term effects. One promising study does not settle a question, and this site is not going to present it as though it does.
The qualifier that matters
UT Southwestern names these directly, and we are repeating them rather than softening them:
Sitting flattens the lumbar curve. Concentrating makes it worse — you slide forward, the pelvis rotates back, and the spine's natural inward curve reverses. Held for hours a day, that is a mechanical stress on the structures that most commonly hurt.
A sit-stand desk interrupts that. Not because standing is a good posture — standing badly is its own problem — but because the interruption redistributes the load. That mechanism also explains why the frequency of switching matters more than the total standing time, and why the 30-minute guidance is the actionable part.
Buying only the desk is the most common way to be disappointed here.
From the picks
The three purchases that together address sitting-related back pain. If you can only make one, make it the chair — you sit more than you stand.
Best current-generation buy
The V2's replacement, and the one that will actually be in stock. UPLIFT puts the range at 22.6" to 48.7" — a lower floor than the V2, which matters more than the ceiling for most people — on the same 355 lb rating and 15-year warranty.

Best chair for back pain
Height-adjustable lumbar support is the feature that matters for a bad back, and this is the cheapest Steelcase that has it — behind a 400 lb rating and a 12-year parts-and-labor warranty.

Best overall standing mat
A deliberately not-flat mat: the mounds and calf shelf exist to stop you standing still, which is the actual cause of standing-desk foot pain. Backed for sixteen years.

Questions
It may help with pain caused by excessive sitting; UT Southwestern cites a study reporting a 50% decrease among sit-stand users. It will not correct structural problems. Nobody on this site holds a clinical credential — talk to a doctor or physical therapist.
No. Standing too much has its own documented risks, and locked-knee standing loads the lower back directly. Alternating is the point.
We do not have data on that and will not guess. What we would say is to change one variable at a time — desk height first, because it is free — so you can tell what is actually helping.
