Those products are then shipped using IKEA’s well-known flat pack strategy. The “assembly required” products are shipped in smaller and fewer containers, allowing the company to get more boxes in vehicles, thus reducing trips, energy use, and emissions. IKEA takes it a step further by making sure optimal loading techniques are used, vehicles run on cleaner fuels, and more fuel-efficient driving practices are followed. To top it all off, only recyclable materials are used for flat packaging.
