Standing Mate Chair

Ergoworks Standing Mate Chair is engineered for sit-stand desks to reduce lower back strain, eliminate posture slumps, and accommodate every way you work. Designed as an all-in-one ergonomic seating solution, it transitions seamlessly between 8 distinct postures—including upright focus mode, straddle horse-riding position, reclined relaxation, perching glute support, lower lumbar leaning, side-leaning stance, forward-lean chest support, and improved-posture kneeling. Featuring a 167° adjustable backrest, lockable twist angle, and an integrated Anti-Fatigue Mate foot cushion, it decompresses the spine while easing pressure on knees, joints, and feet during long work hours.
