Opening Hours: 10-20 / 10-20 / 10-20
IKEA needs no introduction. It is the place to go if you don't want to spend too much money on your furniture and homeware. They even sell woks, shopping bags, and wet wipes. Here's a bit of background about Ikea by The Local.
Below I only explain how to get there.
There are two IKEA stores in Stockholm: Kungens Kurva and Barkarby.
Even if you don't have a car, the one in Kungens Kurva is still accessible via free shuttle bus on weekdays. (Time Out Stockholm says it's daily, but that's wrong.) Every one hour from 10am to 7pm on Monday to Friday, the free shuttle bus departs from Vasagatan 10 (across the street from Stockholm Central station; only 30 seconds from the Vasagatan exit of T-Centralen). It takes about 20 minutes.
To go back to the city center, the shuttle bus departs in front of Ikea (where you got off if you arrived by the same shuttle bus) every one hour from 10:30am to 7:30pm, and stops at Hornstull (T-bana red line), Fridhemsplan (T-bana green and blue lines), Rådhuset (T-bana blue line), and Vasagatan 10.
Alternatively (and on weekends), go to Skärholmen (T-bana red line Norsborg branch) and take bus 707, 710, or 740 for 5 minutes.
