I'm looking for an ergonomic office chair that prioritizes both comfort and support for long hours of sitting. Key features I'm interested in include lumbar support, adjustable height and armrests, and breathable fabric to ensure proper ventilation. It would be great if the chair has a sleek, modern design that fits well in a professional environment. Additionally, I'd like to know about your available color options and any customization possibilities. Please include information about bulk pricing, lead times for delivery, and warranty details. I'm eager to see what you can offer, as I aim to provide my team with high-quality seating solutions that enhance productivity and well-being.
