X-Chair's X4 is a chair that we truly get excited about! X-Chair has taken its highly successful X2 with the super conforming K-Sport Advanced Performance Material back and covered it with top grain or premium leather. The seat is a premium molded foam, carefully wrapped in soft leather. Now you can have the appearance, fit and feel of luxury leather atop a high performing ergonomic chair. Complete with a sliding seat, infinite recline and tilt lock, dynamic variable lumbar support as well as numerous other functions that are listed below, this leather ergonomic task chair will fit your body like a glove and support you throughout your workday. We especially like the X2 chair for its K-Sport material that is unique to the X2 model but now this new X4 leather task chair version sets a new benchmark in performance and comfort. The K-Sport weave foundation back beneath the leather wrap is unique and is only offered on the X4 chair. Coupled with the incredibly well done polished aluminum base, frame and under-structure, this X4 leather executive chair model just exudes beauty and confidence. In addition, the new FS Wheel casters will add a sleek more stable ergonomic foundation to your X Chair! (see details below) Now you can also get the X-Side chair that offers the advanced comfort of Flex Mesh Technology, the unparalleled relief of Dynamic Variable Lumbar support, and the distinctive design of the X-Chair. The X-Side provides instantaneous and personalized ergonomic support for every user in a new uni-body construction. This leather ergonomic task chair Ships Free in 1-2 Business Days. Extensive limited 15 year factory warranty from X-Chair. *Check out the great video on the X Chair functionality in the video tab above!

Design Studio Take-away: If the X2 is the big brother to the X1 ergonomic task chair, then the X4 is the looked up to as the sophisticated cousin. The X4 still includes the superior K-Sport material that is designed to conform to your body's  contours while being supportive and of course breathable. Still featuring a gorgeous polished aluminum base and frame, the X4 builds off the remarkable X2 with a soft and supple genuine leather. This is NOT a bonded, hybrid or 'eco-leather' product.  Like with the other 2 models, the ride of this chair is superior to most others. The underpinnings are robust and well engineered. The recline mechanism is above and beyond what we see in most chairs of this genre. Very strong factory warranty. Not much can be faulted in the overall design and ergonomics that are standard on each of the X1, X2, and X4. We strongly recommend all of the X-Chair models.
