Never feel bogged down again by bad posture with the Knoll Life Chair. With its uniquely designed slim silhouette and flexible mesh back, the act of sitting is made comfortable again. Slender, sleek, and ergonomic to its core, you'll love the intuitive adjustment and recline features, sans all of the levers included on most office chairs. Sitting just got a whole lot simpler.

Add the optional seat and back toppers for even more comfort you can count on.

The Knoll Life chair provides built-in lumbar support with the shape of the back frame and the back suspension fabric. However, the addition of an adjustable lumbar support offers more customizable comfort and superior support. The adjustable lumbar support mounts to your chair with magnets and features slow-recovery foam covered in your choice of three fabrics.
Select from three caster colors available for carpet or hard floors. Glides are also available on the Life ergonomic chair if casters are not necessary.
Back Suspension Fabric Color
All Knoll Life chairs come standard with a mesh suspension fabric that is durable, flexible and available in a wide range of colors.
The Life chair comes with or without a seat topper, and we strongly recommend the purchase of a seat topper for your comfort, especially if you sit for longer than five hours a day. The standard foam seat topper is 1.75" thick. Choose from a wide variety of Knitted, Hourglass, or Cameo fabrics.
Knitted - Base grade
The Knitted Seat Topper is Knoll's standard, base grade material. This lightweight and breathable fabric will keep you cool and comfortable throughout the day.
Hourglass - Grade A
Hourglass is a classic fabric with a dry, wool-like feel. It is composed of 15% polyester, 8% nylon, and 77% post-consumer recycled polyester. A water-based cleaner or mild, water-free solvents may be used for spot cleaning.
Cameo - Grade B
Cameo is a modern fabric with a soft, chenille feel. It is composed of 75% cotton and 25% viscose. For spot cleaning, use a pure, water-free solvent.
Volo leather is a lightly corrected, aniline leather. The light correction process refines the surface so it better accepts the grain enhancement done prior to finishing. Volo receives a special retannage that tightens the grain and provides a finer hand that other corrected leathers.
Sabrina leather is a very popular full grain leather. The special retannage Sabrina receives provides a smooth, tight grain and supple hand, making it an excellent choice for both elegance and high-traffic use. The average thickness is 0.9 - 1 mm, and the average weight is 2.25 - 2.5 oz per square foot. Sabrina leather is Greenguard certified and available in 114 colors.
Ultra Seat Topper
The standard foam Seat Topper is 1.75'' thick. For added comfort, upgrade your seat topper to a 2.25" thick foam Ultra Topper.
Both back and seat toppers snap quickly on or off the Life chair, making it easy to change the look of your chair as often as you'd like. The standard back topper is 3/4" thick foam. The back topper is available in a wide variety of fabric or leather choices to match your seat topper.
A black urethane headrest can be attached to your Knoll Life chair to add extra neck and head support. The headrest features 3" of height adjustment along 12 positions, and is a perfect match to the chair's frame and arm rests.
Please note: The headrest is not compatible with a back topper

I bought this for the looks. After sitting in it I'm very happy it also is extremely comfortable. A Big upgrade from my previous chair. Recommend.

I am very satisfied with the support provided by the Knoll Life Chair and the adjustability of it. The one thing that I would change is that there is no seat topper that is included with the basic chair. I assumed that there would be some sort of cushion associated with it and so did not order a seat topper. However, there is no cushion at all and, while comfortable, the seat gets very hard if you are sitting in it for a long time. I would recommend that some sort of cushion be included with the basic chair.

When I retired, I couldn't bear to leave my wonderful Knoll Life office chair. I was delighted to find that The Human Solution offered all the options available for these chairs. At home now I'm still spending many hours at my computer, and the Knoll Life chair is keeping my back happy.

Chair is very comfortable, but make sure you get the casters for hard floors. If you use a chair mat to move around on, the casters start peeling and make a mess!

Very adjustable. Seat could use a little more padding but that may just be a mesh chair thing. Overall very good.
