Home Office Fixes That Cost Nothing But Save Your Back
Let's get something out of the way: you don't need a $1,500 Herman Miller chair to stop your back from hurting. You don't need a motorized standing desk. You don't need any of the stuff that "best home office setup" articles try to sell you.
Most back pain from working at home comes from a handful of positioning problems. And most of those problems can be fixed with stuff you already have in your house.
I'm not saying nice equipment doesn't help. It does. But if you're choosing between spending money or continuing to hurt, there's a third option: spend nothing and stop hurting anyway.
Here's how.
The Book Stack Monitor Riser
Your monitor needs to be at eye level. Specifically, the top third of your screen should be roughly at eye height when you're sitting up straight looking forward.
Most monitors sit on desks. Desks are too low. So people look down at their screens all day and wonder why their neck hurts.
Fix this in sixty seconds: grab some books, a ream of printer paper, a box - anything sturdy - and stack it under your monitor until the height is right. I've seen people use old textbooks, shoeboxes, even a small bookshelf turned on its side.
Does it look a little janky? Maybe. Does it eliminate the neck pain you've had for six months? Yes. That's a worthwhile trade.
If you're on a laptop, this gets more complicated because raising the screen means the keyboard goes with it. You'll need a separate keyboard and mouse (these don't have to be expensive - any basic ones work), then you can raise the laptop itself to proper screen height.

The Towel Roll Lumbar Hack
Here's a dirty secret about most chairs: they have flat backs. Even the ones that look ergonomic. Even the ones that cost $400.
Your spine isn't flat. It curves inward at your lower back. When you sit in a flat-backed chair, either your lower back rounds out (bad) or your muscles work constantly to maintain the curve (also bad, just slower).
The free fix: roll up a bath towel or small blanket. Place it horizontally in the small of your back, right where your spine curves in. The towel fills the gap between your back and the chair, giving your lumbar spine something to rest against.
This works surprisingly well. It's not as adjustable as a real lumbar support pillow, but it costs nothing and you can do it right now. Experiment with how tight you roll it - some people like it thicker, some thinner.
Your cozy home office chair doesn't need to be replaced. It just needs a $0 upgrade.
The Hourly Alarm System
No setup in the world - not even a perfect one - can overcome eight hours of sitting completely still. Your body needs movement. Period.
But you're not going to remember to move. You're going to get focused on work and suddenly realize you haven't stood up in four hours.
Solution: set a recurring alarm on your phone for every hour. When it goes off, you stand up and move for 60 seconds minimum. Walk to another room. Do some stretches. Get water. Doesn't matter what - just move.
This feels annoying for the first few days. Then it becomes habit. And then you realize your 3pm back pain disappeared because you're not sitting frozen in place for marathon stretches anymore.
Some people use apps for this. Some use their phone timer. Some use their watch. The tool doesn't matter. What matters is something interrupts you before your body locks up.
The Cushion Chair Height Fix
Your chair might be too low. Here's how to tell: when you're sitting, your hips should be slightly higher than your knees. If your knees are at the same level as your hips, or higher, your chair is too low.
Low chair = rounded lower back = back pain. It also means your desk is probably too high relative to your elbows, which creates shoulder problems.
If your chair isn't adjustable (or won't go high enough), add a firm cushion to the seat. Not a soft squishy pillow - that'll compress and you'll sink right back down. A firm cushion, a folded blanket, even a piece of high-density foam.
This raises your seated position without buying a new chair. You might also need a footrest (see below) since raising your seat might leave your feet dangling.
The Box Footrest
If you raise your chair and now your feet don't reach the floor comfortably, you've created a new problem. Dangling feet mean your thighs carry more weight, which puts pressure on the underside of your legs and, eventually, your lower back.
Find a box, a stack of books, a small stool - anything sturdy enough to rest your feet on. Your feet should be flat on this surface with your thighs roughly parallel to the ground.
This is basic home office setup stuff that most people overlook because footrests seem like a luxury. They're not. They're load distribution. Your small home office probably has something that can work as a footrest already - you just need to repurpose it.
The Keyboard Edge Rule
Watch where your keyboard sits on your desk. If it's pushed back toward your monitor, you're reaching for it. Reaching means your shoulders are forward. Forward shoulders mean upper back strain.
Move your keyboard to the front edge of your desk. When you sit properly and rest your hands on the keys, your elbows should be at roughly 90 degrees, directly below your shoulders, not in front of them.
This might mean your monitor needs to move back. That's fine. The distance from your eyes to your screen is less critical than the distance from your body to your keyboard. (Your screen should be about arm's length away - close enough to read without leaning forward.)
One More Thing
All of these fixes are free. They're not pretty, but they work.

The Bottom Line
Free fixes that actually work: books under your monitor (eye level), rolled towel for lumbar support (fill the gap), hourly movement alarms (break the stillness), cushion for chair height (hips above knees), box for footrest (support your feet), keyboard at desk edge (stop reaching).
Your back doesn't care how much you spend. It cares about positioning. Fix that first. For more detail, see How to Fix Posture Working From Home: 5 Changes That Actually Work.
