Percko, a company known for its posture-correcting clothing, has launched an ergonomic office chair priced at 499 euros during a promotion (599 euros otherwise). Designed with input from health professionals rather than marketing teams, the chair includes nine adjustable features, an ErgoAdapt mesh backrest, a SeatCloud seat, a five-year warranty, and a 100-day trial period. Measuring approximately 40 x 53 x 127.5 cm and weighing 21.5 kg, the chair can support up to 150 kg. It features a breathable backrest with a 21° recline angle and five levels of resistance, a high-density foam seat with 92 mm thickness, polyurethane wheels, and multiple ergonomic adjustments for comfort and support. When unboxed, the chair arrived in a large package, requiring ample space to unpack. Inside were the standard components found in most office chairs: base, legs, seat, backrest, armrests, and a screw kit with a wrench. However, the assembly process was reported to be more complex than expected, with two manufacturing defects encountered. The chair’s weight made it difficult to assemble alone, requiring two people for stability. One left armrest had a screw that wouldn’t fit properly, leading to instability. Another issue involved a screw on the chair’s main frame that couldn’t be tightened with the provided wrench due to a manufacturing flaw. Despite these challenges, the assembly process, including time lost due to the defects, took about 45 minutes. For someone without such issues, it should take only 15 to 20 minutes. The chair offers nine ergonomic adjustments, including levers for backrest angle, seat height, and seat depth. These adjustments allow for a 90-degree knee angle and follow body movements without resistance. The armrests can pivot inward or outward, but users noted that more force was required than expected to operate them. Percko claims that 88% of users report reduced back tension and 84% develop better posture habits. The chair’s thick foam seat provided comfort even after 12 hours of continuous use. The mesh backrest and seat remained cool during hot weather. The chair’s recline tension adjustment adapts to the user’s weight, ensuring smooth movement. At 499 euros during a promotion, the Percko chair is priced above some similar ergonomic chairs, such as the Sihoo Doro S300 (around 1000 euros) and the Razer Fujin Pro, which targets gamers. A newer model, the Sihoo Doro C300 Pro V2, focuses on full-body support. The review recommends comparing these options before deciding on a purchase.
