User's Experience

The YAMA7 is mainly made out of mesh, a material that adapts to a user's body instantly since it is quite flexible, durable, and breathable, which makes for a comfortable chair, especially during longer gaming or working sessions. Both the base of the seat and backrest use mesh and padded pleather stripes. The nylon frame of the backrest is reinforced with fiberglass, and its support frame is out of die-cast aluminium alloy for added support and safety. The cyan-colored details on the backrest—playful, sporty, and rather nice—are done with professional-grade automotive paint.


The chair is wide enough for the suggested weight limit, but users weighing 150 kg (330 lb)—the maximum weight limit—might find the base of the seat slightly restrictive.


While it sounds easy, not reading through the user manual might have understanding how to lock all adjustments into place properly take a while. If done properly, the backrest's and embedded lumbar support's adjustable features result in an almost perfect sitting experience by offering more than just a relaxing experience—it is as if sitting in an ergonomically designed hammock! We have a high work station in our lab, and it seems the Yama7 lacks a bit of height for it. I would like to be able to reach higher working areas. The steel class-4 gas lift responsible for all height adjustments is of good quality and filled with nitrogen gas.


The backrest's maximum 135° recline angle is not as high as with other chairs, but this is also an office chair with ergonomic features, and a recline of 130° results in the most relaxed sitting posture according to Mr. Niels Diffrient, as per his book "Humanscale." The rocking mechanism only applies to the backrest—the base of the seat cannot be tilted. Other models of the Yama series have both a tiltable backrest and seat. Tilting back the backrest is easy—you only have to press down the paddle under the armrest.


The chair's profile is comparatively slim because it does not use any foam, so it will fit in places where most gaming chairs wouldn't. The 2D armrests do take away from the chair's overall ergonomic feature set. 4D armrests would be the better fit because all other features are rather high-end.


The caster wheels are the typical 60 mm across. They are stable on flat surfaces and roll nicely when force is applied. However, on a carpet, more force is required because surface and user weight result in more resistance.


The Yama7 only has a one-year warranty that extends to two years by law in Europe. For such a build, the warranty should at least be two years across the globe.
