A standing desk is often bought as a fix for back pain and ends up causing a different kind of it, because the desk itself isn't the variable that matters most — how it's used is. The three most common mistakes are all avoidable, and none of them require spending more money.
Going from an all-sitting day to standing for hours at a stretch doesn't build tolerance, it just shifts strain from your lower back to your feet, knees, and hips, which weren't conditioned for sustained standing either. The realistic approach is starting with 20-30 minutes of standing per hour and building up over a few weeks, not switching to standing all day on week one. Most people plateau at roughly a 1:1 or 2:1 sitting-to-standing ratio across a workday, not standing the majority of it.
The standard guidance — elbows at 90 degrees when standing — is a starting point, not a fixed rule, and a lot of people set it once and never adjust for different shoes or tasks. Set the desk so your elbows rest at roughly hip height with shoulders relaxed down, not shrugged up. If you switch between flat shoes and shoes with any heel, that changes your standing height enough to matter — a desk set correctly for sneakers will sit slightly too low once you switch to boots.
Standing on a hard floor concentrates pressure on the same points of your feet for the entire time you're upright, which is where most standing-desk knee and lower-back complaints actually originate — not from the desk height. An anti-fatigue mat with some give changes this by letting your feet make small, constant micro-adjustments instead of staying locked in place. Look for at least 3/4-inch thickness; thin mats under half an inch don't compress enough to make a real difference.
Rather than a strict schedule, most people do better switching position based on the task: sit for deep focus work and long typing sessions, stand for calls, reading, or shorter tasks where movement is natural. Alternating this way tends to produce more actual position changes over a day than a rigid timer, because task-based switching happens more often without feeling forced.
New lower back tightness that appears specifically during standing sessions (not sitting) usually means the desk height is off, not that standing itself is the problem. Foot or heel pain that builds through the day points to missing or inadequate mat support. Knee discomfort when locked in one position for a while is a cue to shift weight more often — standing desks don't fix a static posture problem, they just move where it happens if you stand as rigidly as you sat.
Cutting through it: a standing desk is a tool that requires adjustment habits, not a fix that works by itself. Get the height and mat right, and build up standing time gradually — most of the complaints about standing desks trace back to skipping one of those two things.

Yes — an anti-fatigue mat at least 3/4-inch thick reduces pressure on the feet and is linked to fewer knee and lower-back complaints than standing on a hard floor.
New back tightness during standing sessions usually means the desk height is set incorrectly, not that standing itself is the problem. Elbows should rest near 90 degrees with shoulders relaxed.
