Research suggests that alternative seating options like stools or benches may promote better posture and muscle engagement compared to chairs with backrests. Traditional chairs with backrests tend to make sitting more passive by providing support that reduces the need for muscle activation. In contrast, seats without backrests require individuals to engage their core muscles for stability while sitting, leading to improved posture and increased muscle engagement. This type of seating encourages a more active sitting position that can help prevent issues like weak backs and back pain associated with prolonged periods of sitting.
