It is not recommended to sit on a wobble cushion all day. While wobble cushions are designed to promote active sitting and improve core strength, prolonged sitting on a wobble cushion may cause discomfort and even exacerbate existing musculoskeletal issues. It is recommended to use a wobble cushion intermittently throughout the day, alternating with periods of sitting in a stable chair or standing. It is important to listen to your body and adjust your use of the cushion accordingly.
