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.

    M57 is a super comfortable chair made with quality materials that feel durable and well put together. The wheels roll smoothly and make it easy to move around my desk without any effort. The seating position feels natural, and the lumbar support does a great job keeping my back aligned during long hours of work.

    The armrests are nicely shaped and comfortable for daily use. This is a great choice for the price, and I am very happy with my new M57.

    I received the office chair as ordered. The packaging of the parcel is really impressive and of high quality. For all sorts of screw and washer you get a spare unit. The assembly of the chair is very well explained and easy to do with a pair of gloves included.

    I recommend this office chair
