cushion lab seat and lumbar cushions

honestly any lumbar and seat cushion set helps. i got a super cheap set a long time ago and they make my ergonomic chair way more comfy. that said, my sister has the ones from cushion lab and they're genuinely fantastic. makes sitting feel weightless. i ordered a set for my partner who reported way less back and hip pain. personally don't think the foot rest is as necessary unless your knees are sloping downward and pulling your back forwards at rest. don't buy full price, they have frequent sales.
