A good chair often means one that comes with a variety of adjustments. Branch's Ergonomic Chair fits this bill. It's surprisingly easy to assemble in minutes (the instructions are great), and there are tons of little tweaks you can make. You can push the armrest back and forward, up and down; the seat can extend out or be pushed all the way in; you can lock the recline; and there's even adjustable lumbar support. It does all this while managing to look very sleek and without asking an outlandish price. (There's no headrest but you can pay to add one.)

It doesn't keep my back as upright as I'd like, but the double-woven nylon mesh backrest feels nice to lean against. The seat is made of high-density foam—it's firm yet comfy—and it doesn't trap heat as much as other foam seats I've tried. It's a great chair for a variety of body sizes; my 6'4" self enjoyed sitting on it, as did my 5'1" partner. Fair warning though: Pet hair tends to cling to the upholstery. 

Ask WIRED reviews director Jeffrey Van Camp what the best office chair is and he'll point you to the humble Hyken. It's frequently available for just $170 during big sale events, making it one of the most affordable good options out there. It reclines, has a breathable mesh fabric on the back and seat, and it's sturdy. You even get a headrest and lumbar support. After three years of continuous sitting, Van Camp says the mesh has compressed a bit, but it's still comfy. However, it may not be the best option if you need a wider seat. 

No one wants a swampy butt. There, I said it. Thick foam seats often trap your body heat, especially during the summer months. That's why I like the X-Chair. It doesn't just have a mesh backrest, but the seat is mesh too, allowing for excellent airflow. It also feels like you're sitting on a hammock. Who doesn't want that? Every part of my body feels well supported, and you can adjust nearly everything on the chair. Pull the seat up and push the armrests up, down, and side to side, or angle them in or out. The lumbar support feels like a cushion, and it adjusts as you move in your seat. 

If you want to rest your head, you can pay extra for the headrest. Speaking of which, X-Chair has a number of models to choose from. I tested the X-2 K-Sport with the wide seat, and it fit my 6'4" frame really well. But it was too wide for my partner, who is 5'1". Most people should be fine with the standard X1. The only things I dislike? X-Chair offers up various cooling, heating, and massage attachments, but I didn't find them all that helpful. The chair is also very expensive.

A Familiar Alternative: The Mavix M7 ($778) looks strangely similar to the X-Chair, and that's because both are owned by the same company. I ran into some issues with assembly, but customer service was able to exchange the model without much effort. The M7 has similarly adjustable armrests and seat angles, but you get wheels that lock. The mesh back and wide seat construction keep you cool and comfortable during a sweaty session of League of Legends, and the lumbar support makes me feel like I'm in good hands. If you're short, contact customer support while ordering—Mavix offers shorter cylinders so your feet touch the ground.
