I tested the OdinLake Ergo Max A747 and sitting in this ergonomic office chair brings a relief I didn't know was possible

OdinLake's previous flagship, the Ergo Plus 743, was one of my favorite chairs I have ever tested. I prefer chairs to be firmer. When I'm sitting in a chair, I don't want to be enveloped by it, so I prefer a slightly firmer chair to start with.

The fact that OdinLake tends to be firm, combined with the choice to use mesh material, which keeps the sitter cool and features smooth casters, makes this my chair. Additionally, it features excellent ergonomics and is highly adjustable, all while maintaining a high weight capacity, so I have no concerns.

The O2, also known as the Ergo Max 747, is the upgraded version of the Ergo Plus 743. It utilizes the same material, design, and build quality and adds a few fantastic features. They upgraded the leg rest and the lumbar support and added a jacket rack to the back of the chair, making things just a tad better overall. How does it stack up against the best office chairs I've reviewed? I took it for a test ride.

OdinLake Ergo Max A747: Pricing & Availability

The OdinLake O2 retails for $899.00, though at the time of writing this article, the OdinLake listing shows it on sale for $799. It has a 30-day return policy in case you, for some reason, do not like it, and it comes with a 15-year warranty, ensuring you'll be covered for at least that long, if not significantly longer. It's available from OdinLake.com and a few other select retailers.

OdinLake Ergo Max A747: Unboxing & first impressions

The OdinLake O2 (also known as Ergo Max 747) was delivered in a large box, which contained the chair pieces, the necessary tools for assembly, and some instructions.

I built this chair myself in about 18 minutes, but keep in mind I had built a chair just like this before, so it wasn't new to me.

Right off the bat, I loved the design; I noticed just how similar it is to the last model I tested while still retaining its unique features in certain areas.

I love the look with the mesh and metal frame. It even looks good with my mostly Dark Walnut office with dark accents.

The biggest standout, of course, is the three-section backrest, and it's a bold look for sure, but I don't hate it; in fact, it's growing on me. It makes other chairs look like they are missing something, and this chair is not only hefty but also high-end.

OdinLake Ergo Max A747: Design & build quality

The OdinLake design for their flagship chairs has remained consistent, featuring an aluminum alloy frame, black mesh, and a sturdy base. The O2 features a distinctly designed backrest with three sections — one for your shoulders, one for your mid-spine, and one for your lumbar support. These independent sections help ensure that my back is supported better than in other chairs I have sat in that are just a single section.

The mesh is one of my favorite aspects of this chair; it's something I genuinely love. It's sturdy and doesn't feel like it's giving way, yet it's comfortable, and, of course, it's very breathable. As someone who is typically warm, regardless of the time of day, year, or what I'm wearing, having a chair that helps keep me cool rather than warm me up more is a must-have at this point.

The armrests are also really solid. Unlike some chairs that I have tested, where 4-D armrests are the bane of their existence and make for a super touch-and-go experience, I am wondering if adjusting or standing up using the armrest will be the thing that drops me to the floor due to giving way (dramatic, but based on a true story), these armrests are stable, secure, and sturdy to where I do not hesitate leaning on them, standing up pushing off of them, or adjusting to get more comfortable in the seat if needed.

OdinLake Ergo Max A747: In use

Not only is this chair adjustable from the jump, but it's also dynamic and moves with me during the day. I've spent (admittedly) many 9-to 12-hour days sitting in this chair, only getting up briefly. Usually, I like to rotate to standing, but that's not always something I remember to do or feel like doing, especially if I'm locked into a project. The O2's dynamic lumbar support moves with me, allowing for some flex, but in a way that adds support rather than getting out of the way.

This chair offers valuable insights with its suggested heights listed on the website. It's best for those who are 5'3" to 6'3". I'm right in that range, at 6'1" -6'2", depending on the day. This chair feels like it's made for people my height. I've had some taller friends enjoy this chair still, and some that are a tad shorter, though once you get closer to that 5'5" mark, you're going to feel like the chair is oversized.

For my larger friends, this chair is designed to accommodate those weighing 300 - 350 lbs as well. I'm currently floating around 200 lbs, so I had a buddy of mine, who is pushing 285 lbs, come and try this chair. I kid you not; he hasn't sighed relief like that since he tried my last OdinLake chair.

For those who followed my last review or are familiar with the OdinLake Ergo Plus 743, the most significant difference I've noticed is that this chair feels like a true "version 2" of the 743. The leg rest system has been upgraded and is easier to use. The lumbar backrest system has also been upgraded, and a jacket holder has been added to the back for use in a friendly office environment. You don't want to get your sports coat wrinkled or wear a jacket on a cold or rainy day. Everything else feels like it was all slightly improved, but perhaps that's just a matter of perception in light of the other upgrades.

OdinLake Ergo Max A747: Final verdict

All around, this chair is fantastic. It's one of my personal favorites for a reason. If you're looking for one of the best ergonomic chairs available, if you're over 300 lbs or over 6'2", if you run hot, or if you want a remarkably comfortable chair for long hours, the OdinLake Ergo Max A747 (O2) has knocked it out of the park. It's pricy, but it's worth every penny.
