Assembly varies from chair to chair. The Aeron comes 95% put together, for example, and only requires the attachment of the chair back using four screws. The Steelcase chairs, on the other hand, require more assembly. If you are concerned about chairs fitting into your car, we recommend bringing tools with you to disassemble the chairs. Chairs picked up from our showroom can just be wheeled out. Chairs picked up from our warehouse are fully assembled and covered in stretch wrap.
