What should I buy for back pain from sitting all day?

Start with a lumbar support cushion and a footrest if you sit all day. They’re relatively low-cost, easy to try, and directly address the two common sitting problems: your lower back losing its natural curve and your hips/knees being poorly positioned. If your chair is worn out or unsupportive, consider an ergonomic office chair next. For flare-ups, a heat/ice pack can help short-term, but it won’t fix the sitting setup.

Best buy order:

1. Lumbar support cushion — best first purchase for lower-back support.
2. Adjustable footrest — best if your feet don’t rest flat or your chair/desk height is awkward.
3. Seat cushion — helpful if pressure, tailbone discomfort, or hard chairs make pain worse.
4. Sit-stand desk converter — useful if it helps you change positions, but don’t just stand all day.
5. Heat/ice pack — good for temporary relief during painful episodes.

Also buy yourself a timer habit: take brief movement breaks once or twice an hour. For sitting-related back pain, frequent breaks are often more helpful than any single accessory.
