Important 700 Seat Pan Information

Unless you have used or tried the 700 seat pan, we do not recommend purchasing it without testing it first. The contours of this seat pan are full and will fit some people perfectly, while others may not align properly with the deep contours. If you think the 5700, 6700, or 8700 ergonomic chair is for you, find a local dealer or retail outlet and test the chair. Chances are you will fall in love with this line of comfortable, attractive and durable office chairs. If you try it and like it, please buy the computer chair from the person and organization who provides you the evaluation chair and their time. It is certainly fair to pay considerably more than our online prices when you get in-person service in a showroom.
