What difference is there between this chair (M57) and the cheaper M18, other than the 3D adjustable armrests?

Dear Customer, In addition to upgrading the armrests of the M57, the cushions and backrest areas are also made of more advanced, durable, and breathable mesh fabrics.

I want to buy a chair that is more supportive. I am 185cm/85KG. May I have an introduction?

Our latest ergonomic Office chair Doro C300. This chair is designed with independent waist support, which can better meet your needs.

Can the back be locked in position at different angles?

Just to confirm, the chair CAN actually be locked in reclined position. Recline back to desired level and then push the lever in to fix the position

You have stated to provide "zero profit product accessories within three years of warranty period", what does this mean?

If the product you purchased is under warranty and there is a problem with the parts of the chair, we will provide you with free new parts to replace.
