We Tried the Percko Ergonomic Chair: Comfort Delivers, But Luck Wasn’t On Our Side!

Percko has built its reputation on posture-correcting clothing, and it seems the brand has now decided that their customers’ backs deserve better than a run-of-the-mill office chair bought off the shelf. Enter the Percko ergonomic chair, currently priced at 499 euros (599 euros without the discount), promising expert-designed support rather than marketing-driven features. On paper, it has everything to convince: nine adjustments, ErgoAdapt mesh backrest, SeatCloud seat, five-year warranty, and a hundred-day trial period to make up one’s mind. We’ve received the chair, unpacked it, and gave it a test.

Technical Specifications

Assembly: Our Chair Came with Two Stubborn Screws

Upon receiving the package, the first observation was the size of the box, appropriate for a complete office chair, requiring some floor space for unpacking. Inside, we found the usual components for this type of chair: base, piston, seat, backrest, armrests, and a bag of screws with an included wrench. Assembly is supposed to be straightforward. However, we encountered two manufacturing flaws that made the process less enjoyable than expected.

Before even reaching for the wrench, note that the chair is heavy—21.5 kg as stated by Percko—and it’s noticeable when fitting the two main blocks together. We definitely recommend having a second person help with this part: it’s doable alone, but it quickly becomes tricky to keep everything stable while aligning the components.

Each armrest is normally secured with three screws. On our left armrest, only one of these screws could be inserted and tightened properly. The second one went in without issue, but the third simply refused to go in, regardless of the angle or pressure applied. The left armrest holds, but without its third point of fixation, it’s unstable. If you press down on it, as one naturally would when leaning on the arms to stand up, it moves and feels insecure over time.

The second issue was with a screw in the main trunk, which fixes a central part of the structure. Here, the problem was different: it was impossible to insert the provided wrench into the screw head, which seemed to have a manufacturing defect. We had to resort to hand-tightening, which obviously does not achieve the necessary torque. The screw holds, but it’s not as tight as it should be.

In total, assembling the chair, including the time spent dealing with these two stubborn screws, took just under 45 minutes. For someone handy who doesn’t have to deal with defective screws, assembly should take about 15 to 20 minutes.

Ergonomic Adjustments

Once assembled, the Percko offers access to its nine settings, distributed between the backrest, seat, and armrests. Under the seat, there are several levers managing each specific function, and it takes a bit of fiddling to identify them all.

The large lever on the left locks the backrest tilt: turn it back to lock the backrest in the chosen position, forward to allow movement. The large lever on the right adjusts the tension of this tilt, clockwise for more resistance, counterclockwise for easier tilting. A flat lever, also on the right, adjusts the seat height over an 8 cm range. On the front left, another lever slides the seat forward or backward to adjust the depth, and on the back right, a final dial locks the seat in a horizontal position or allows it to follow the movement of the pelvis forward. Once these adjustments are made, the result is tangible: sitting normally, the knees form a right angle, and the chair follows the body’s movements without resisting or letting you fall.

The armrests are supposed to pivot slightly inward or outward to match the position of the arms, in addition to being adjustable in height via a button underneath. On our model, this rotation is indeed present, but it’s currently quite stiff to operate, requiring more force than expected. It’s hard to tell at this stage whether this will ease with use: on our model, it requires effort.

Day-to-Day Comfort

Percko claims that 88% of users experience less back tension with this chair, and 84% report adopting better postural habits. And in practice, it’s easy to see why. The foam of the seat is thick and dense, and even after spending a good part of the day on it, it’s impossible to feel discomfort in the posterior even after 12 consecutive hours in front of the screen. It’s these kinds of details that make all the difference in a workday.

After a month and a half of daily testing, it’s clear that the seat makes all the difference with this chair. It’s cushy without ever sagging or losing its form. Another unexpected plus: during heatwaves, we never felt overheated sitting in it. The breathability of the mesh backrest and seat truly does its job. The final ingredient is the adjustment of the tilt tension: once you find the right sensitivity for your own weight, the chair supports every movement without ever feeling like it’s working against you.

Price and Competition

At 499 euros on promotion, the Percko is priced above similar range ergonomic chairs. Competing models like the Sihoo Doro S300 typically retail around 1000 euros, while the Razer Fujin Pro targets gamers seeking ergonomics. More recently, the Sihoo Doro C300 Pro V2 focuses on support that adapts to the entire body, offering a basis for comparison before making a decision.
