The Sitmatic GoodFit is one of the company's best-selling ergonomic chairs — but is it the right chair for you? In this Sitmatic GoodFit review, I'll take you through my experience with a customized version of the GoodFit and share the pros, cons, and everything in between.
My verdict up front: the GoodFit is one of the most thoughtfully designed ergonomic chairs I've tested, with outstanding PressureCast cushioning, memory foam armrests, and an optional tailbone cutout. It's best for people willing to customize carefully. In my configuration, the prominent lumbar support clashed with the tailbone cutout, and the headrest only helped in a full recline — so plan your seat size and control mechanism around your body.
Disclaimer: I received this chair at no cost after attending Sitmatic University. While I didn't pay for it, I am committed to providing an honest review that highlights both the strengths and limitations of the chair.
Key takeaways
- Standouts: PressureCast foam that holds its shape, wide memory foam armrests, Aerohide upholstery, and an optional tailbone cutout.
- The sliding seat helps you keep a 2–4 finger gap between the seat edge and the back of your knees.
- In my setup, the built-in lumbar protruded above the tailbone cutout; a larger seat pan or the SynchroEnhanced control may fix this.
- Skip the headrest if you mainly work upright at a desk — it only engages in a full recline.
- Best for buyers who want a high-end chair and will plan their customization carefully.
Why Did I Choose the Sitmatic GoodFit Chair?
I chose the GoodFit because it's Sitmatic's flagship ergonomic chair, and I wanted firsthand experience with their top model to see how it measures up against other premium office chairs on the market. Although this version is customized, I'll clearly note which features are standard and which were upgraded so you can make an informed decision.
I selected the standard seat and back sizes, along with the Multifunction (MF) control mechanism, which is highly recommended for ergonomic seating. The sliding seat function, in particular, allows you to achieve optimal posture by maintaining a 2–4 finger gap between the edge of the seat and the back of your knees. Seat depth is one of the ergonomic chair features that matter most, so I was glad to see it handled well here.
My configuration at a glance
| Feature | Standard or upgrade | My take |
|---|---|---|
| PressureCast cushioning | Standard | Plush, holds its shape, doesn't sag |
| Multifunction (MF) control with sliding seat | Selected option | Great for posture; better for shorter legs |
| Memory foam armrests | Upgrade | Highly recommended for mouse users |
| Tailbone cutout | Custom feature | Excellent pressure relief, but conflicted with the lumbar in my setup |
| Aerohide upholstery | Upgrade | Soft, breathable, worth the cost |
| Headrest | Upgrade | Skip it unless you recline often |
What Do I Love About the GoodFit Chair?
Four features stood out: the memory foam armrests, the tailbone cutout, the Aerohide upholstery, and the standard PressureCast cushioning.
1. Memory Foam Armrests
These wider-than-standard armrests are made of soft memory foam and offer excellent comfort — especially while using a mouse. They adjust in height, width, and pivot angle, making them one of the most versatile armrest options I've experienced. If your budget allows, I highly recommend this upgrade for improved arm and shoulder support.
2. Tailbone Cutout
As someone with lower back pain, I found the tailbone cutout a game-changer. It's a small, discreet indentation in the rear of the seat — covered with fabric — that reduces pressure on the coccyx area. This thoughtful customization demonstrates Sitmatic's deep understanding of seating ergonomics. If you're considering any custom features, this should be your top priority. However, I did run into one issue related to this feature, which I'll explain below.
3. Aerohide Upholstery
This synthetic leather (polyurethane with reinforced rayon backing) exceeded my expectations. It's soft to the touch, breathable, and does not stick to your skin — making it ideal for long hours of sitting. While it's one of the more expensive fabric options, the upscale appearance and performance make it well worth the cost.
4. PressureCast Cushioning (Standard)
Sitmatic's proprietary PressureCast technology uses a special foam formulation cast under high pressure. The result? A cushion that feels plush, holds its shape over time, and doesn't sag after hours of use. It's one of the most comfortable seat foams I've experienced — and it stays that way day after day.
What Didn't Work for Me (and What Could Be Improved)?
The main issues were a conflict between the tailbone cutout and the lumbar support, the need to unlock the rocking mechanism to use both, sensitivity to seat height, and a headrest with limited use at a desk.
Tailbone Cutout & Lumbar Support Conflict
The GoodFit's built-in lumbar support is prominent and supportive — but in this custom setup, it clashed with the tailbone cutout. The lumbar protrudes above the cutout area, making it difficult to position my lower back comfortably even with the seat slider fully extended.
If I could do it over, I would select a larger seat pan so the tailbone cutout aligned better with my anatomy. Alternatively, switching from the Multifunction control to SynchroEnhanced may have provided more seat depth for taller users. I'd recommend:
- Multifunction for users with shorter legs
- SynchroEnhanced for those with longer legs or needing more seat flexibility
Rocking vs. Fixed Seating
To benefit from the cutout and lumbar support simultaneously, I had to unlock the rocking mechanism. This allowed me to recline into a position that engaged both features — but it isn't ideal for someone like me who spends 8+ hours typing at a desk. I prefer a fixed seating angle just slightly beyond 90 degrees for productivity and posture.
Height Sensitivity
To truly appreciate the ergonomic design of this chair, you'll need your feet flat on the floor or a properly adjusted footrest, such as the Sitmatic Footsie Footrest. If your desk is high, the chair must be lowered accordingly — otherwise, you won't fully benefit from its ergonomic shaping.
Headrest
I'll be blunt: the headrest is not worth it unless you plan to recline often. The large lumbar support prevents your upper back from resting flush against the backrest, which in turn means your head doesn't contact the headrest. It only becomes useful when the chair is in a full recline position — more suitable for relaxing or gaming than working.
If your primary use is office work at a desk, I suggest skipping the headrest and saving your money. Headrest fit is a common pain point across premium chairs; Aeron owners, for example, can read about Aeron accessories that fix common complaints, including aftermarket headrests.
Final Verdict: Is the Sitmatic GoodFit Worth It?
Yes, for the right buyer. The Custom Sitmatic GoodFit is one of the most thoughtfully designed ergonomic chairs I've ever tested. Its comfort, adjustability, and build quality are top-tier. The PressureCast cushioning, memory foam armrests, and tailbone cutout make it a standout option for those seeking long-term seating support.
That said, the lumbar-torso alignment issue with the tailbone cutout and the limited use case for the headrest are drawbacks to keep in mind — especially if you're looking for an ergonomic chair for all-day office work in a fixed position. If you're still deciding whether a premium chair is worth it at all, here's a look at the real benefits of an ergonomic chair.
Who should buy it
- Best for: People who want a high-end ergonomic chair and are willing to customize for personal needs
- Not ideal for: Users with long legs who need deep seat pans (unless opting for SynchroEnhanced) or those expecting full use of a headrest
- Customization tip: Tailbone cutout + larger seat + SynchroEnhanced = best ergonomic combo for taller users
A near-perfect ergonomic chair with excellent customization options — but plan carefully to get the right fit.

Frequently Asked Questions
Is the Sitmatic GoodFit chair worth it?
For people who want a high-end chair and will customize it carefully, yes. The PressureCast cushioning, memory foam armrests, and optional tailbone cutout are excellent. Plan your seat size and control mechanism around your body, and skip the headrest if you mostly work upright.
Which Sitmatic control should I choose: Multifunction or SynchroEnhanced?
In my experience, Multifunction suits users with shorter legs, while SynchroEnhanced is better for longer legs or anyone who needs more seat flexibility. If you're adding a tailbone cutout and you're on the taller side, SynchroEnhanced with a larger seat is the combination I'd choose.
Does the GoodFit tailbone cutout help with lower back pain?
It reduced pressure on my coccyx area noticeably. The catch is alignment: in my setup, the lumbar support sat above the cutout, so a larger seat pan may be needed for the two to line up with your anatomy.
Should I get the headrest on a Sitmatic GoodFit?
Only if you recline often. The prominent lumbar keeps your upper back off the backrest, so your head doesn't reach the headrest while you work upright. It becomes useful mainly in a full recline.
Are Sitmatic chairs good for petite users?
Sitmatic builds chairs for many body sizes, and the GoodFit can be configured with different seat and back sizes. For very short users, Sitmatic's dedicated Little Person chair with a footbar is usually the better starting point.
