Sabrina Leather

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.

Volo Leather

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.

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.



Professor Ergo's Thoughts:

I like to recommend the Knoll Life Chair to people looking for a comfortable ergonomic chair that's easy to use and adjust. This is a slim and efficient chair that offers a lot of support without the bulk. The Life Chair may look slight, but it's a strong ergo chair that's built to last with high quality materials. Add the optional seat and back toppers for more cushiony comfort.

  • Completely satisfied with the desk. More impressive was the buying process, knowledge of the sales and support staff, and attention to detail. It's clear that this company is on a mission to help people. They have found a way to differentiate themselves in a crowded market and stand out as a great company which deserves all the success it achieves. We will be adding a second UpLift 900 in the near future. Thank you!
