There is not a single thing, there are several issues with ikea and there furniture 1. The information provided with large furnitures is not enough 2. The furniture comes with parts those if you by mistake attached wrong place then you have to through it and buy the other expensive one. 3. Ikea furniture is one time assembly furniture, once you assembled then you can not dismantle. If you try then everything will be useless. So its a fully wastage of money. 4. The assembling all the parts need lots of patience, time and use of your full of the brain. 5. If you are not comfortable any technical assembling, then do not buy since you can not return the ikea stuff 6. Ikea delivery sucks. The illiterate people will deliver your stuff and if they count it wrong then its a nightmare to get those stuff from ikea using there customer service. 7. To get customer service, you have to wait on the phone not less than 30 min. They will force you indirectly to listen there all ikea stuff. 8. I spent $4000 on kitchen furniture and ended up to through about $2000 stuff in the garbage due to incomplete delivery, certain things were beyond my understanding because of complicated guide book was provided. I realized that better to pay extra $2000 to local shop and get everything what you like. If you are middle class and has a limited budget then dont buy anything from ikea otherwise you will also end up writing such review.
