Best Office Chair Under $300 (2026): 4 Ergonomic Chairs Tested

The honest truth about office chairs under $300: none of them are as good as a used Herman Miller Aeron off Craigslist for $400. But not everyone has a local used market, and there are a handful of sub-$300 chairs that will keep your back happy through an 8-hour workday without making you hate your life. After testing six of them over six weeks with help from a friend who is a physical therapist, here are the four I’d actually buy.

Quick picks

• Best overall: Branch Ergonomic Chair. 7 adjustment points, real lumbar, under $300 shipped.
• Best mesh: Sihoo M57. The best mesh office chair under $200. Ships with a real adjustable headrest.
• Best budget: Hbada Ergonomic Office Chair. Under $150 and comfortable for 4-6 hour workdays.
• Best for tall users: Autonomous ErgoChair Pro. Designed for users 6’0″ and up, where most chairs compromise.

1. Branch Ergonomic Chair – Best overall

The Branch is as close as you can get to a real $600 ergonomic chair for under $300. The big deal is adjustable lumbar depth – most chairs under $300 have fixed lumbar, which either hits your back wrong or doesn’t hit it at all. Branch lets you move the lumbar support in and out to match your spine. Add 3D armrests (height, width, and angle) and a seven-year warranty and you have a chair that will last the length of two normal office jobs.

2. Sihoo M57 – Best mesh

Sihoo is the Amazon budget chair brand that actually delivers. The M57 is the chair I recommend first to anyone asking “I need a decent chair, I can’t spend $300, what do I buy?” The full mesh back keeps you cool in a hot room, the lumbar is height-adjustable (most cheap chairs skip this), and the headrest actually reaches your head without you tilting your neck unnaturally. The tilt tension knob is surprisingly good.

3. Hbada Ergonomic Office Chair – Best budget

The Hbada is not going to last ten years. But for under $150, it’s comfortable, it has a mesh back, and the retractable footrest is a genuinely nice feature for mid-afternoon breaks. Good pick for students, first apartments, or anyone who isn’t sure they’ll keep working from home long-term.

4. Autonomous ErgoChair Pro – Best for tall users

Most office chairs under $300 are built for users 5’6″ to 5’11”. If you’re 6’2″, the headrest hits your shoulder blades and the seat cuts into the back of your thighs. The ErgoChair Pro is one of the few sub-$300 chairs that genuinely fits taller users, with a deeper seat pan and a headrest that reaches the back of your head. It’s our tall-friend pick for home office setups.

What to look for

• Adjustable lumbar. Fixed lumbar is a coin flip. Adjustable (up/down AND in/out) is what you actually need.
• 3D armrests. Height, width, and angle. Fixed armrests cause shoulder pain after a few weeks.
• Seat depth matters. Your knees should not touch the front of the seat. A chair with a seat slider is better than guessing.
• BIFMA or Class 4 gas lift. Cheap gas pistons sink during the day. Class 4 or better holds position.
• At least a 2-year warranty. Fabric and mesh wear fast on cheap chairs. Warranty is the proxy for build quality.

FAQ

Should I just buy a used Herman Miller Aeron?

If you can find one locally for $400-500 in good condition, yes. Aerons from 2010 onward are mechanically bulletproof and outclass every chair on this list. The catch is shipping a used Aeron costs $150-200, which kills the deal. Local pickup only.

Do I need a mesh chair?

Mesh is great if you run hot or live somewhere humid. Foam seats are warmer and often more comfortable for shorter users. It’s a preference thing, not a quality thing.

Which would you buy?

Branch for a home office you actually work in. Sihoo M57 if the budget is tight. ErgoChair Pro if you’re over 6 feet tall.
