The Marvin black desk chair features plenty of thick plush padding for comfort along with an embellished mesh trim throughout the chair. Its high back extends to the upper back for greater support. The high back design relieves tension in the lower back, preventing long term strain. The included headrest will take the pressure off of your neck while leaning back. The tilt lock mechanism offers a comfortable rocking/reclining motion. The free rein motion is great for taking a quick break from typing to answer phone calls and relax. The waterfall front seat edge removes pressure from the lower legs and improves circulation. Chair easily swivels 360 degrees to get the maximum use of your workspace without strain. The pneumatic adjustment lever will allow you to easily adjust the seat to your desired height. The chrome base adds a stylish look to complement a contemporary office space.
