Last week, Sarah—a marketing manager in Manchester—messaged our support team at 4:47 PM. The message was simple: "I can't turn my head to the right anymore." By Friday, she'd rung in sick. By the following Monday, she was back, but something had shifted. She wasn't just uncomfortable. She was frightened.
Sarah isn't alone. UK workers now take an average of 9.4 days off sick per year—the highest on record. And most of it—if not all of it—points back to the same root cause: their chair.
We don't want to say this is the whole story. But we will say this: if your neck's screaming at 3 PM, it's not because you're working too hard. It's because you're using something that fundamentally doesn't respect how your body works.
Understanding Neck and Shoulder Pain in the Office
You've probably heard someone say posture is the key. Sit up straighter. Adjust your posture. Raise your screen.
It would be lovely if that worked.
The problem is: this advice assumes you can maintain "good posture" for eight hours. But you can't. Nobody can.
You'll lean forward to read a spreadsheet. You'll recline to think. You'll tilt sideways to grab something. You're not static. But your chair usually is.
What happens to your cervical spine when you lean forward—even just 15 degrees?
Research shows that this angle increases the pressure on your neck from 5 kilograms to roughly 12 kilograms. Lean forward another 15 degrees (where most people end up when looking at their keyboard), and the pressure jumps to 18 kilograms.
Your neck muscles—particularly the deep cervical flexors—simply aren't designed to bear this weight all day long. Within a few hours, they start to fatigue. Within a few weeks, you feel a burning sensation. Within a few months, you're considering a career change.
Here's what most people miss: the problem isn't your posture. The problem is static loading.
You're trying to perform a dynamic, ever-changing task on something rigid and immobile. Your body makes constant micro-adjustments. Your muscles compensate continuously. Your spine adjusts constantly. All day long.
This isn't tiredness. This is injury.
Why Shoulder Pain Happens When You Work at a Desk
Now shift focus to your shoulders.
Your shoulders are the bridge between your neck and your hands. The trapezius—that large muscle running from your neck down to your upper back—is responsible for supporting the weight of your arms.
What happens when your chair's armrests are fixed too low, positioned too far away, or simply in the wrong place? Your elbows drift downward naturally. To compensate, you unconsciously shrug your shoulders—just slightly, but it's a subtle, constant movement. This state of "perpetual shrugging" creates trigger points in your upper back.
By 5 PM, it's not just your neck. Now it's your neck and your shoulders.
We talk to users, and they'll say something like: "I didn't realise I was shrugging all day." Once they notice it, it's hard to stop seeing it everywhere.
The Problem with Most Office Chairs for Neck Support
Most office chairs follow the same formula:
You have a fixed backrest angle. You have a static lumbar support cushion. You have rigid armrests. Maybe you have a headrest—a pad you have to adjust manually that becomes useless the moment you tilt, lean forward, or stretch.
The problem with this design? It assumes you'll sit in one position.
But you won't.
A chair actually designed for relief needs to do three things:
First, it needs a headrest that actually moves with you. Not something you manually lock into place. Something that tracks your neck curve, whether you're typing, tilting, or resting. Your C1 to C7 vertebrae need support, regardless of your position. Most chairs fail at this.
Second, it needs a mechanism that tilts with you. When you recline to relieve neck pressure, your seat should move with your backrest—not stay flat, leaving you in a "hammock" position where your shoulders roll forward. You need synchronised recline that keeps your spine neutral, even when you're resting.
Third, your armrests need to move with you. When you recline, your elbows change position relative to your torso. A fixed armrest becomes a liability. You need something that adjusts in multiple directions—up and down, forwards and backwards—and can sync with your recline.
This sounds like a lot. It really isn't. It simply means a chair that respects what your body actually does, rather than forcing you into a single position it prefers.
How Sihoo Engineered Solutions for Neck and Shoulder Relief
When Sihoo's engineers looked at why office workers end up with chronic neck pain, they identified a fundamental problem: most chairs treat sitting as a static position.
In reality, sitting is dynamic. You lean. You stretch. You tilt to reach for something. You recline to think. Your chair either moves with you or works against you.
That's why they built two different models from the ground up. Not designed for comfort. Designed for pain relief.
Sihoo Doro C300 for Active Work and Neck Pain
If your main complaint is neck pain, the C300 is our answer.
This chair was built around the headrest, not as an afterthought. It has a self-adaptive mechanical headrest that adjusts its angle automatically as you type. It doesn't ask you to pause and manually tweak it. It simply...adapts.
TechRadar tested it and said: "The headrest is excellent." They didn't say "looks nice." They said it works.
Your lumbar support tracks every movement you make. When you lean forward to check a spreadsheet, the support's there. When you recline, it adjusts. Your spine stays neutral throughout your working day.
The armrests adjust in three directions. That means, regardless of your frame, you can find a position where your arms are supported and your trapezius can actually relax.
The material? High-elasticity mesh. Breathes beautifully in a UK home office. Not cold. Not hot. Just...comfortable.
If you spend eight hours a day typing and in meetings, and all you need is for your neck to stop screaming, the C300 is exactly what you need.

Engineered with adaptive lumbar support, 4D adjustable armrests, and a breathable mesh design, the Doro C300 delivers all-day ergonomic comfort and effortless recline.

Now, imagine your problem isn't just your neck. Imagine your entire body is screaming. Your shoulders are tight. Your lower back is stiff. You work 10 hours. You're exhausted by 2 PM.
The C300 might do the job. But the S300 is for when you need something more.
This chair uses aerospace-grade fibreglass plates. Why does that matter? Because it allows a different kind of recline—one that feels genuinely weightless. When you lean back (up to 135 degrees), you don't just tilt. You feel yourself floating.
Research shows that this near-zero-gravity position reduces spinal disc pressure. Your spine decompresses. Blood flow returns. Your tissues get a chance to recover, not just survive.
Here's what happens when you recline like this on most chairs: your shoulders roll forward. That "hammock" feeling. The S300 doesn't work that way. It keeps your shoulders in neutral position as you recline.
It has 6D armrests. Sounds complicated—it's actually simple: your armrests move in six different directions, including syncing with your recline. This means whether you're sitting bolt upright or fully reclined, your arms are supported. Your trapezius doesn't have to do the work.
It has two independent lumbar pads that adjust separately. Most people's spines aren't perfectly symmetrical. The S300 accounts for that. You can fine-tune each side independently.
The material? Italian velvet mesh. It sounds luxurious because it is. It feels warmer during Britain's cooler months. Yet it still breathes. This isn't the "I'm sweating" material. This is the "I'm genuinely comfortable" material.
It won the German Design Award in 2023. It's been recommended by Forbes, TechRadar, and CreativeBloq.
Right, let's be honest. That extra £370 is real money. Is it worth it?
It depends. If you work in an office and spend most of your time typing, the C300 might be perfect. But if you're sitting all day and need a rest every few hours, or you're just someone who spends serious time in a chair...yes. The extra features will change your life.

One Honest Note About Office Chair Solutions
A good chair won't fix everything. You still need to move. You still need to stretch. You probably need regular breaks. If you sit on a brilliant chair and work in exactly the same way for eight hours, you'll still have problems.
But a good ergonomic chair stops making things worse. It stops the constant micro-adjustments. It stops the shrugging. It stops the forward lean. That matters more than you'd think.
Getting Started with Pain Relief
If you've read this far, your body is probably telling you something needs to change.
Order the chair that matches your pain situation. Sit in it for 30 days. Notice how you feel at 5 PM. Notice after a week. Notice after a month.
Most users see a difference within a week. Not "miracles happened." But "wait, I'm not in pain all day."
That's why we're confident offering a 30-day return guarantee. Once you feel the difference between genuine support and pushing through pain, you'll know whether it was worth it.
