Before adding support, first identify which contact point is not making contact: feet, lower back, or head/neck. Adding too many cushions at once may shorten the seat depth or push your body away from the backrest.
Feet dangling: Address the floor first
After adjusting the chair height to match the desk, if your feet still cannot stably touch the ground, consider a footrest. The height should ensure your thighs are not pressed against the seat edge, and the footrest should not obstruct the chair legs or aisle.
Lower back off the backrest: Check thickness and fastening method
Lumbar support should fill the gap, not push your body forward. Measure the width of the backrest, the path of the fastening straps, and the seat depth; adjustable thickness or segmented designs are easier to adapt to clothing and sitting postures.
Headrest used only in appropriate situations
Headrests primarily provide contact when leaning back, taking short breaks, or watching content. There's no need to intentionally press your head back when typing normally. For taller headrests, ensure the backrest structure and fastening straps can provide stable support.
Change only one thing at a time
After adding a new accessory, use it for several days consecutively, observe your posture, how you get up, and desk operations, then decide if a second item is needed. This way, you'll know which item is truly helpful.
