Flash Furniture's high-back mesh chair is a cheap desk chair, but it borrows ergonomic design cues from nice desk chairs. The all-mesh build keeps you cool while working, and adjustable armrests plus a headrest and built-in lumbar support offer more support for your body than you'll find in other sub-$200 task chairs.
Will it last you a decade? Will it feel like an expensive chair? No and no. But, marked down to just $125 today, it's a very nice deal on a product everybody is looking for.
