The best times to shop for unsold and marked-down IKEA patio furniture tend to be around spring or summer. Then, the first IKEA summer sale occurs at the start of the season, usually running through parts of June and July. These events happen when many shoppers are searching for the perfect outdoor furniture for relaxing and enjoying the warmer weather. Also, like almost every other retailer, IKEA runs annual Black Friday and Cyber Monday events in late November. You may be able to find bargains on indoor IKEA furniture that works for outdoor spaces, as well as items like accent lighting and storage solutions for your patio.
