Factory Direct via Rakuten offers the BestOffice Mid-Back Ergonomic Mesh Office Chair for $44.99. Coupon code "OFFICE20" cuts that to $35.99. With free shipping, that's the lowest price we could find by $5. (For further comparison, we saw it bundled with $5 in Rakuten points for the same price in February.) It adjusts from 19" to 23" in height. Note: The coupon can be used once per household within a single transaction with one merchant.
