The seat and back toppers are also available in any Spinneybeck leather (www.spinneybeck.com) and optional perforations are available. Please call or email us for pricing on leathers not listed.

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.

For added comfort, add a 2.25" thick foam Ultra Topper.

Our Customers Say ...
I received the chairs today and they are perfect. Thank you for your personal attention to my shipping snafu. In this day and age of the internet and push button instant gratification, we sometimes forget that the real value is not in a price that is 1% better. It's in the value added by empathetic people how really try to help. Maybe you should create a company tag line like "Real humans providing great human solutions."
