We are a fully authorized dealer for the Ergohuman Chair series. The Raynor Ergohuman series is made up of six different models. Each chair has standard features such as a sliding seat-pan, adjustable height backrest and pivoting armrests. Features like these allow the Ergohuman to adapt to almost every user effortlessly. The ME7ERG, LEM4ERG and LE9ERG each include an adjustable headrest. We do not recommend the headrest for customers that are under 5’3” and over 6’4” tall. Our most popular Ergohuman model is the ME7ERG, a high back mesh chair that compares favorably to the Aeron®. The full mesh Ergohuman chair is a great choice for those looking for a high end mesh chair. Beyond The Office Door’s recommended models are the LEM4ERG and LEM6ERGLO, a hybrid of the full mesh and leather models. These two chairs include a leather seat and mesh back rest. We believe the leather seat offers slightly better support over the mesh model when sitting for extended hours. Most of our customers sitting 7-8 hours a day in these chairs would agree the firm leather seat really can be more comfortable.
