An excellent choice for executives who require built-in lumbar support, the Glenmore Black Posture Chair by Porch & Den stuns in its sleek design. The LeatherPlus upholstery adds a softness that you won't find with other chairs and the fact that the material is so durable is a welcome bonus. Users love that the unit can be adjusted to match their height and depth preferences, as well as the thick pads that make the seat more comfortable.
