The innovative lumbar support if the highlight feature of this chair.

Beyond the lumbar support, features are decent. One thing lacking that other pro chairs have is a multifunction tilt-lock. That lets you tilt and lock the seat at angles, independent of the backrest. Instead of a multifunction tilt, the Iskur chair comes with a cheaper standard version. That only lets you rock the chair, or lock at a flat angle.

  • Functionality: 4D armrests; depth-adjustable lumbar; seat height adjustment; rocking function.
  • Upholstery: black faux leather with carbon trim and green stitching.
  • Size rating: 5’6″ to 6’2″ (170-190 cm); up to 299 pounds (136 kg).
  • Warranty: 3-year warranty from Razer.

Mini-review: most Razer products charge a premium price, and the Iskur chair is no exception. It has decent features and a solid warranty, but no multifunction tilt-lock. That means less functionality than pro chairs. On the plus side, the Iskur chair’s lumbar support system is the most advanced on the market.


The Razer Iskur looks more like a marketing move than a revolution. It adds a unique new feature by addressing a problem that doesn’t exist. For example, a standard gaming chair pillow compresses when the user leans back. In that sense, it is depth-adjustable according to the user’s lumbar curve. Unlike the Razer Iskur, a cheap gaming chair pillow is also height-adjustable.

Built-in lumbar systems like the Secretlab Titan also do a great job. All extend out far enough to fill the lumbar curve of most users. While the Razer Iskur goes deeper, it does so an awkward angle. Instead of filling the lumbar curve, it jabs hard plywood into the upper part of the curve. It sounds awkward and uncomfortable.
