A chair provides support for a user in two configurations. The first configuration is a normal sitting position. The second configuration is a partial kneeling position. A knee cushion assembly is extendable from a stowed position under a tiltable seat cushion to an extended position in front of the seat cushion for the user's knees. When the knee cushion assembly is extended, the rear of the seat cushion is tilted upwardly to provide support for the user's buttocks.
