Tonfary's 819 is a large mesh chair aimed at users from 160 to 192 cm, and it backs that claim with a sliding seat and a tall backrest. The seat is roughly 50 cm deep and moves forward for longer thighs, while the back stands around 75 to 80 cm. With a 150 kg rating, it suits people who are both tall and broad but do not want to stretch to premium prices.

Our take
Dimensions that matter for tall users
Tonfary lists the seat at about 50.5 cm wide and 50 cm deep, with seat height running from roughly 45 to 55 cm. The overall chair stands about 116 to 130 cm tall depending on height setting, and the backrest itself measures around 75 to 80 cm. That tall back is the main reason long-torsoed users will find it supportive between the shoulder blades.
The sliding seat moves forward and back, though the listing does not give the distance in centimetres. A waterfall front edge eases pressure behind the knees.
Back and lumbar design
The backrest is split, with elastic mesh across both halves providing what Tonfary calls full-lumbar support. There is no separate adjustable lumbar pad: support comes from the shape and tension of the back. The tilt has three angles, upright at 90 degrees, a balanced 115 and a relaxed 130.
Arms, headrest and assembly
The 3D armrests have soft PU pads and move about 7 cm up and down and 7 cm front to back, and they swing sideways. The detachable headrest rises about 5.5 cm and rotates 30 degrees. Assembly takes around 25 minutes with the included tools, and the chair weighs about 21.5 kg. The listing does not state a warranty length, so ask before ordering.
How it sits against rivals
The ProtoArc EC300 is aimed slightly higher, up to 195 cm, with a 6 cm rising back, but is rated for less weight. The Elabest X100 reaches a 58.5 cm seat height and adds a footrest, though its seat depth is fixed. The CAPOT mesh chair carries 181 kg with 8-level lumbar. The Tonfary is the balanced choice for tall, broader users.
Verdict
Buy the Tonfary 819 if you are tall and broad, want a sliding seat and a tall back, and are happy with built-in lumbar. If you are very tall but lighter, the ProtoArc EC300 fits a longer back, and if you need a higher seat with a footrest, the Elabest X100 is a better match.
