Walmart offers the Comfort Products Leather Mid-Back Office Chair in Black or Brown, model no. 60-5607M, for $44.88. (Amazon charges the same price for the black model, however it isn't expected to ship for three to five weeks.) Choose Site-to-Store pickup to dodge the $9.97 shipping fee. That's tied with last week's mention and $18 under the lowest shipped price we could find. Features include lumbar support, pneumatic height adjustment, and curved armrests.
