Backrest

The backrest is 48 cm (18.9") wide and 76 cm (30") high.


The backrest's height can be adjusted by lifting the backrest. A "click" means it has locked in place. To set it to its original position, pull it up and let it drop down.


The frame of the backrest is made out of reinforced nylon with a fiberglass overlap, and its support frame is made out of die-cast aluminium alloy.


An embedded mechanism with cushioning and a lever on each side is for height adjustments of the built-in lumbar-support system, which ensures it offers support wherever it may be needed.


The paddle under the left armrest allows you to lock or release the backrest, which has an adjustable angle that ranges from 90° to 135°. You may set it to drop back freely or lock it into a certain position.


A handle underneath the seat allows you to adjust the tension of the backrest.


Our sample is cyan and black in color. The stitching is color-matched and of exquisite quality.


Padded, breathable PU stripes with geometrical shapes on the backrest and seat make for a more powerful look and increase comfort. Mainly because of its appearance, the Yama7 can be used in both gaming and working environments. It also complies with the office chair standard ANSI/BIFMA X5 1-2013.


The company name and logo are embroidered in gunmetal and cyan on the headrest, while a metal plate with the logo has been added to the rear of the backrest.

Seat Base

The sitting area is 50 cm (19.68") wide and 50 cm (19.68") deep. There are no contoured edges, which means the entire seat is available for use. I like soft-cushioned chairs better, but the mesh material is very comfortable to sit in.


This chair has a high weight limit and is, as such, reinforced with a back-support frame made out of die-cast aluminium alloy, a sturdy base, and durable, wide casters to better support larger users.


The Yama7 is 123–133 cm (48.42–52.36 ") tall, which has the seat's height off the floor range from 48 to 58 cm (18.9–22.8 "). A paddle under the right armrest adjusts the height of the chair.


A button on the left side of the seat allows the base of the seat to be moved forwards and backwards, which is a nice feature to have for larger users.
