The Deal: Herman Miller Aeron chairs up to 40% off at Allmodern.com

Many people are working long hours from home these days and, for many, a good office chair isn't a luxury but a necessity. Herman Miller's Aeron chair is considered among the best, ergonomically. Yes, the chairs are pricey but fans see it as an investment in comfort, let alone style.

Allmodern.com is offering several Aeron models for 30% to 40% off, depending on the style. The Basic chair begins at $629, reduced from $932, and the Loaded Work Stool rings up at $1,349, down from $2,042. (Arms, casters and lumbar extras increase the base price.) Buyers' comments include the suggestion to check if the armchairs are adjustable before you purchase.

Used Aeron chairs can be found on Craigslist and EBay but they are still fairly expensive, averaging about $500. As an authorized Herman Miller dealer, Allmodern will honor the manufacturer's 12-year warranty. It also offers free same-day shipping, no sales tax (unless you live in Massachusetts) and a price guarantee: If you find an Aeron chair elsewhere for less, Allmodern will match the price upon verification.
