How to Sit in a Chair
To sit correctly in a chair, push your body all the way back until you touch the backrest. Use lumbar support to help your lower back keep its natural curve. This helps your spine stay straight. Adjust the height of your chair so your feet rest flat on the floor. Your knees should bend at about a 90-degree angle. Leave some space behind your knees to allow for good blood flow. Check that your elbows are close to your body. Keep your arms relaxed. Follow these tips for a comfortable sitting position!
