Best Ergonomic Gaming Chairs in 2024

The best ergonomic gaming chairs can bring a finishing touch to a new PC gaming rig while preventing chronic neck and back pain.

Great ergonomic office chairs have been available for years, but companies like Secretlab, Herman Miller, and Sihoo are doing in-depth research to deliver the best ergonomic health to PC users everywhere. While the former two brands may be recognizable to most office workers and gamers, Sihoo hasn’t quite reached household name status. However, their newest ergonomic chair, the Doro S300, offers a highly customizable alternative to traditional options.

Sihoo’s Ergonomic Designs

Founded in 2011, Sihoo’s focus on ergonomic health was improved upon with their establishment of the Sihoo Ergonomic Furniture Research Institution. Taking notes from their competitors, Sihoo has cultivated a team of over 100 experienced professionals specialized in ergonomics, engineering, and well-being, creating ergonomic office chairs using science-backed designs.

Similar to Secretlab, Sihoo spends hundreds of hours testing each new chair, ensuring dynamic support for good posture while seated at a desk, fostering a balance between intuitive comfort and ergonomics. This has paid off well, as Sihoo ergonomic office chairs became the best-selling computer chair in Europe in 2020.

Most of their chairs are built to keep PC users cool and rely on mesh fabric to support them. Despite being made mostly of mesh, clever engineering has led to a variety of shapes that offer targeted ergonomic support along various pressure points. Some chairs have separate lumbar supports, some aim to provide even support along the entire back, and still others relieve leg pressure with thickly padded seats.

For instance, the affordable Sihoo M102C provides users with a memory foam seat cushion that’s over three inches thick, plus adjustable lumbar and head support, all while being available for less than $200. Sihoo’s line also caters to users who prefer less intrusive designs, offering ergonomic chairs like the Sihoo M57 Full Mesh seat, which supports good posture using an adjustable, bi-directional lumbar support on the back of the chair, rather than through a separate piece on the front.

With every new Sihoo chair comes more dynamic ergonomic support and overall improved designs. Sihoo builds on their innovations with each iteration of their mesh chairs, clearly aiming to offer the best ergonomic chair for office workers and gamers alike.

From ergonomic design to breathable mesh, these office chairs are not only perfect for work but also excel in providing great comfort in gaming.

The New Doro S300 Ergonomic Chair

Sihoo Doro S300 innovation

The Doro S300 Ergonomic Chair is Sihoo's flagship ergonomic chair, was released in December of 2023 and stands as a testament to years of hard work from the company’s team of ergonomic experts. Purporting to “defy gravity”, this ergonomic chair with lumbar support promises a springy, yet sturdy seat, ideal for people who often sit for long periods of time in front of their desk. Not only does the Doro S300 offer an airy and comfortable chair for those late nights in the office or online with the squad, but the almost bouncy springs make it easier than ever to take a break and walk around or switch to a standing desk for a bit.

A 6th-Generation Innovation

The Sihoo Doro S300 chair is the 6th time the company has innovated their ergonomic designs, and the proof can be found in the advanced suspension system and the anti-gravity reclining system, which uses aerospace-grade glass fiber to evenly distribute weight and make movements fluid. That reclining movement automatically coordinates with other parts of the chair too, including the dual-lumbar support and the adjustable armrests.

The shock-absorbing suspension system is based on the same designs used in cars and other vehicles, with the same durability built-in. One of the biggest problems with mesh seat bases is that they often have significant pressure points. Sihoo’s S300 on the other hand, utilizes four springs beneath the seat cushion to effectively distribute weight across the entire seat, which also works to eliminate that uncomfortable “hard landing” that happens sometimes with cheaper office chairs. Once again, this is great news for users who are in front of their computers for hours at a time, as it’s important to stand and stretch frequently. With the S300, sitting back down feels like resting on a cloud.

Ultimate Adjustability

The adaptability of the Doro S300 cannot be understated. It’s clear that Sihoo’s ergonomic design extends beyond standard office use to offer a comfortable seat for gamers too. Gaming chairs were once leaders in the world of ergonomic chairs, but now office chairs are becoming more and more alluring to competitive gamers.

Long gaming sessions are less than ideal in the wrong chair, however, with the Doro S300, players can really make the chair their own with the vast amount of customizability available. First and foremost is the dual lumbar support, which is made up of two mesh panels with four omnidirectional springs that allow users to move each panel according to their specific height and weight. Along with this is the fairly unique independent backrest, which can also be adjusted to one of five total heights, supporting a wide variety of body types.

Other than these standout adjustable parts, users get the standard array of customizability, though even this is done better than most. The seat adjustments, which allow users to change the depth, height, tension, and recline of the chair, are all conveniently placed together, clearly labeled and uniquely shaped so that users can quickly identify each switch or knob to change their ergonomic chair on the fly. On top of this, these settings automatically adjust when a user reclines, so that an individual’s settings translate even when the chair is at an odd angle.

Premium Materials

The Doro S300 looks like something out of a sci-fi movie, especially with the clean white finish against the shiny, durable metal frame. That frame, made with a single piece of aluminum alloy, is strong enough to support up to 300 pounds, perfect for most users. At the same time, the mesh fabric outdoes the competition thanks to its being made with high-end DuPont TPEE Italian velvet. This material is strong enough to stay rigid even after years of use, yet is flexible enough to provide a consistently cushy and soft feel.

With excellent contouring, especially around the lumbar, head, and neck areas, paired with top of the line materials, the Doro S300 leverages its many features to provide gamers with one of the best ergonomic chairs for back pain without sacrificing adjustability and comfort in the process.

Investing in a Quality Ergonomic PC Chair

Sihoo Doro S300 new

Despite only having been recently released, the Doro S300 has already been tested and certified by BIFMA and SGS, while also garnering recognition from the German Design Awards. Plus, there are already dozens of independent reviewers talking about how the Doro S300 helped them finally get a hold of their ergonomic health and eliminate pains caused by poorly made chairs. Although it’s priced at just about the same rate as Herman Miller’s luxurious line, gamers, students, and office workers may find that Sihoo’s desire to compete has pushed their Doro S300 high above more established brands.

You can currently save $100 on the Doro S300. Plus, if you share a photo of their new chair by April 25th on either the Sihoo website or on Instagram, they will have the chance to win Apple AirPods Pro (2nd generation), an Apple Watch SE, a PlayStation 5, free orders, and more!
