10 Best Office Chair Under 100 2025 in the United States

The TRALT Office Chair is a solid choice for anyone looking for an affordable ergonomic chair under $100. It provides good support for your head, back, hips, and arms with adjustable features including seat height, headrest, backrest tilt, and flip-up armrests. This makes it comfortable for people roughly between 5'5" and 6'2" to sit for long hours, whether working or gaming. The breathable mesh seat helps keep you cool, and the foam cushioning offers decent comfort without being too soft or hard.

Its sturdy metal base supports up to 330 pounds, which is great for heavier users, and the chair’s 360-degree swivel and smooth rolling wheels work well on hard floors, making moving around your workspace easy and quiet. Assembly is straightforward with all tools included, which is a nice bonus. However, since the material is primarily mesh and foam, it may not feel as plush as leather or heavy padding chairs, and it might not suit those who prefer a very cushioned seat.

The chair's dimensions are suitable for average-sized adults but might be a bit tight for larger body types. While it’s highly adjustable, it lacks advanced ergonomic features like adjustable lumbar firmness or headrest angle beyond height. This chair balances comfort, adjustability, and durability at a budget price, making it ideal for home office users or students needing a practical and supportive seat for extended use.

The GABRYLLY Ergonomic Office Chair is a solid choice for those seeking comfort and support on a budget, especially suitable for people between 5'5" and 6'2". It offers good ergonomic features, including lumbar support and a headrest, which help reduce strain during long hours of sitting. You can adjust the seat height, backrest tilt (90° to 120°), and flip-up armrests, allowing more flexibility to fit your workspace and sitting preferences.

The breathable mesh material keeps air flowing, which is great if you tend to get warm while seated. The cushion is wide and supportive, designed to accommodate larger builds up to 400 pounds, making it a reliable option for bigger users. Mobility is smooth thanks to PU wheels that work well on hard floors without scratching. Assembly is straightforward and tools are included, backed by a reassuring 5-year warranty.

Some limitations include its unsuitability for users shorter than 5'5" and the mesh seat, which, while breathable, may not offer the plush softness of some padded chairs. The reclining feature is limited to about 30 positions, which provides adequate but not extensive adjustment. For those seeking a functional, adjustable office chair that supports different body types and offers decent comfort without breaking the bank, the GABRYLLY fits well within the under $100 category.

The Amazon Basics Classic Puresoft Mid-Back Office Chair offers good value for anyone looking for an affordable option under $100. It has a simple, clean design with cream-colored Puresoft PU upholstery that feels soft and easy to clean, which suits a home office or conference room setting. The seat and backrest include padding with foam cushioning, providing decent comfort for moderate daily use. Adjustability is present but limited to seat height, seat angle, and tilt control—enough to help you find a comfortable sitting position but missing advanced ergonomic features like lumbar support or adjustable armrests.

The chair supports up to 275 pounds and features a sturdy metal base with smooth-rolling caster wheels, so it should be stable and mobile on most indoor floors. Its mid-back design offers fair support but may not be ideal if you need full upper back or neck support for long hours. Assembly is straightforward, making it easy to set up without tools. On the downside, the build is lightweight at around 28 pounds, which might affect durability over time if used heavily. The armrests are fixed in height, which could limit comfort customization.

While the cushioning is comfortable initially, it may compress faster than higher-end chairs. For those seeking a basic, budget-friendly office chair with essential adjustments and good mobility for light to moderate use, this product fits well. However, if strong ergonomic support for longer periods or a chair that can handle heavier use is needed, other options might be more suitable.
