Kneeling posture opens the hip angle on this ergonomic chair, tipping the pelvis forward so the lower spine keeps its curve instead of collapsing into a slouch through a long desk session. The seat and knee pad are built over a multi-layer board core with 3.1 inches of foam under a linen cover, thick enough that shins stay comfortable across a full work block. A solid wood frame measuring 33.2 by 19.9 inches carries up to 265 pounds and allows a slight rocking motion, which keeps the sitter shifting rather than locking into one fixed position. Seat height adjusts to match different desk heights and leg lengths, and the 16.1 by 11.6 inch seat cushion pairs with a 19 by 9.8 inch knee pad so weight is shared between hips and shins. Overall dimensions are 32.2 by 21.2 by 21.8 inches at 17.6 pounds, compact enough for a home office, a study nook or a meditation corner. Spot clean the linen with mild soap.
