How to choose a right ergonomic office chair?

Check out our buying guide for you!

M57 is comfortable to sit on, whether that's for a couple hours or more a proper marathon work slog. It's functional and keeps you upright in a comfy way. And I suppose that's sort of perfect given it's a work chair.

from CREATIVE BLOQ, M57 ergonomic chair review

A quick turn of the wheel behind the chair can lessen or deepen the intensity, and I’ve found that when working, the soft retention against my spine keeps me comfortably upright.

If your budget can’t stretch to the higher one, consider M57 fully adjustable ergonomic chair by Sihoo, it comes with a remarkable array of adjustable features and it is great for plenty of adjustments and breathable mesh.

    Chair is very comfortable, easy to assemble, with excellent lumbar and head support. Minor firmness in seat, but overall highly recommended.

    Best chair I’ve had.

    I’m 4’11” and love that the M18 lets me adjust the seat height, armrest height, and lumbar support so it fits me just right. The lumbar support and headrest feel great, and it actually helps me sit up straighter even though I usually have pretty bad posture. I do have to use a foot rest because at desk height, my feet don’t touch the ground lol. Assembly took me about 20 minutes, which wasn’t bad at all. The chair is on the heavier side, so I needed my husband’s help carrying it upstairs once it was fully put together

    After a month, this chair is still super comfortable. I love how adjustable it is, though I do wish the headrest could be a bit higher for my 5'11 height. Still, for under $300, it is an awesome deal.

    This is hands down the best ergonomic chair I have ever owned. At this price point, it is hard to find such comfort and adjustability. The horizontal lumbar adjustment is a huge win for back support. The armrests adjust outward, and at 6 feet tall, the chair supports my posture perfectly. Highly recommended for anyone working from home.

    The chairs that I bought before were too soft and negatively affected my younger son back. With this chair, it has an adjustable back piece that supports the spine. The head and arm pieces are adjustable as well. The whole chair also has a woven design which gives it good ventilation.
