GABRYLLY vs. SIHOO M57: Which Budget Ergonomic Chair Actually Supports Your Back

Here is the short answer: both the GABRYLLY ergonomic chair and the Sihoo M57 are decent chairs for the price, but they solve the problem differently, and one of them is more likely to still feel good six months from now. If your lower back is already talking to you after a long morning at the desk, you do not have much patience for a chair that requires six tries to dial in. I picked up the GABRYLLY after sitting in a kitchen chair for two years at my home office desk, and I tested both options before committing. This comparison lays out what I found.

The GABRYLLY runs around $190 at current Amazon pricing. The Sihoo M57 typically comes in around $150. That $40 gap matters, but it is not the whole story. Cheaper chairs have a way of costing you more in the end if the lumbar support flattens out or the arm pads crack after eight months. Let me walk through the real differences.

Where the GABRYLLY Wins

The biggest edge the GABRYLLY has is what I'd call real adjustment range. The flip-up arms are not a gimmick. If you work at a keyboard all day, being able to fold the armrests out of the way when you stand up or pull close to your desk is genuinely useful. The Sihoo M57 has fixed arms, and if the height does not land right for your desk, that is just how it is. Fixed arms at the wrong height will tighten your shoulders over a long day faster than no arms at all.

The headrest on the GABRYLLY is the other thing that separates it. Most people doing real work at a desk lean back occasionally, especially on calls or when reading. Without a headrest, you are craning forward or resting your head against nothing. The Sihoo M57 skips the headrest entirely, which keeps the price down but leaves a gap in support that matters if you sit for more than four or five hours at a stretch. The GABRYLLY's headrest adjusts in both height and tilt angle, so it actually fits behind your neck instead of poking you in the back of the skull the way cheaper fixed headrests do.

The warranty is worth mentioning too. Three years on the GABRYLLY versus one year on the Sihoo M57. A chair that is going to sit under you for five or six years while you run a side business, teach remotely, or manage a freelance workload needs to be backed by something more than twelve months. That three-year coverage reflects the manufacturer's own confidence in the build.

Where the Sihoo M57 Wins

The Sihoo M57 costs less, and for someone who genuinely sits lightly, maybe three hours a day for email and light tasks, that price difference is the whole conversation. It also puts together faster. The GABRYLLY requires a bit more time and patience at assembly, nothing complicated, but the Sihoo is a simpler chair with fewer parts, so you are sitting in it sooner. If you are not mechanically inclined or just do not want to spend an evening with an Allen wrench, the Sihoo is the easier build.

The Sihoo also has a cleaner, lower-profile look. Some people find the GABRYLLY's headrest and tall back a little imposing in a smaller room. The M57's silhouette is less office-park and more minimal. If aesthetics matter to your space, that is a real consideration. A chair you like looking at is one you are more likely to keep.

Who Should Buy Which

Buy the GABRYLLY if you are sitting for five or more hours a day, if you have existing lower back or neck stiffness, if you are on the larger side and want the extra seat width and higher weight rating, or if you want a chair that will hold up for several years without the lumbar foam pancaking. The GABRYLLY is also the right call if you want the flexibility of flip-up arms, since once you have had them you will not want to go back to fixed arms at a desk.

Buy the Sihoo M57 if your daily chair time is lighter, if you are on a tight budget and the $40 difference matters, or if you want a faster, simpler assembly and a sleeker profile in a smaller home office. It is a respectable chair at its price point, but it does not have the depth of adjustability or the warranty coverage to compete at five or six hours a day over a multi-year stretch.

Fixed arms at the wrong height will tighten your shoulders over a long day faster than no arms at all. The flip-up design on the GABRYLLY is not a gimmick, it is the feature that earns the price difference.

A Closer Look at Build Quality

I have spent most of my working life looking at how things are made, and a chair is not so different from any other piece of furniture. You notice the base, the welds on the frame, the quality of the gas cylinder, and whether the mesh will stay taut or start to sag. The GABRYLLY uses a nylon mesh back with a fairly dense weave that holds its shape well. The base is five-pronged nylon, which is standard for this price range, and the casters roll smoothly on both hardwood and low-pile carpet.

The Sihoo M57 uses a similar mesh construction, and to be fair it does not feel cheap. But the back frame has a bit more flex to it than the GABRYLLY, and the armrests on the Sihoo are a harder plastic with foam padding that is thinner than what you get on the GABRYLLY. After daily use over months, padding thickness under your elbows becomes more noticeable, not less. The GABRYLLY's armpad foam is denser and the cap is a bit wider, which distributes pressure better.

The tilt mechanism on both chairs runs in the same 90 to 120 degree range. The GABRYLLY's tilt tension dial has more distinct positions and feels more precise to adjust. You can set a firm resistance for focused work and a softer lean for reading or calls without the chair feeling like it is fighting you. The Sihoo's tilt mechanism works but has less tunable range, so you are choosing between pretty stiff and a single softer lock.

Lumbar Support: The Detail That Matters Most

Both chairs have built-in lumbar support rather than a separate add-on cushion. That is the right approach for all-day sitting, since a clip-on cushion slides around and ends up doing nothing useful by afternoon. The GABRYLLY's lumbar support is a contoured section of the back frame that sits right in the lower-back curve when the seat height is dialed in. It is firm without being pointy, and it holds its position without drooping over time the way foam inserts tend to.

The Sihoo M57's lumbar support is built into the mesh frame at a fixed position. For some people that fixed height lands exactly right. For others, especially taller or shorter users, it either pushes above or below where the lumbar spine actually sits. This is the reason dedicated adjustable lumbar support matters. If the support is in the wrong spot, it is not supporting anything useful and may actually push your spine into a worse curve than no support at all.

If back support is the main reason you are shopping, that single factor tips the decision toward the GABRYLLY. You can read more about how proper chair adjustments affect lower-back pain over a full workday in the guide on 8 ways a good ergonomic chair fixes back pain.

Long-Term Durability and What to Expect

At this price tier, no chair is going to feel like a $900 Herman Miller. What you are looking for is a chair that holds its shape, keeps its adjustments, and does not develop a creak or a lean within the first year. The GABRYLLY's 14,000-plus Amazon reviews with a 4.4-star average across a wide range of body types and usage hours is a meaningful data point. That sample size is large enough to filter out the outliers, and the pattern in long-term reviews is that the chair holds up well past the one-year mark.

The Sihoo M57 has a smaller review base and a shorter warranty, which makes its multi-year track record harder to verify. That is not a knock, it just means less information to go on. When you are making a purchase that you plan to sit in for 30 or 40 hours a week for three or four years, more information is better.
