Buying products from IKEA comes with many perks, including affordable furniture that is easy to personalize. That said, it does come with downsides that are routinely cited by customers. While it's normal to have gripes against companies that mass-produce their products, it can be worth knowing what some of those complaints are — especially if you are a newer consumer of the Swedish giant's pieces. Beyond the list of things you should never buy from IKEA, other concerns you might run into include missing mounting hardware, near-impossible product assembly, and inaccurate delivery windows, to name a few. Whether you choose to continue shopping at IKEA (there are plenty of seasoned IKEA customers who do so despite the common complaints) or decide to take your business elsewhere, being aware of the company's shortcomings can help you adjust your expectations and plan accordingly to provide you the best possible shopping experience.
