It’s so crazy that it actually might work..
Ikea has a ten year/life time warranty. My neighbour goes back with used, worn out furniture every few years and receives a new set for free (or with a high discount, I'm not sure). Apparently not many people do this so Ikea hasn't changed their rules yet.
Edit: So according to an anonymous IKEA employee the return/warranty policy is very lenient as this makes returning stuff easier for both the customer and the employees. If it's obvious you are abusing their system or the items have been treated without care warranty will be refused. It also depends on the item and how many there is in stock.
I asked my neighbour and he told me he returned a broken dining chair, a sofa and part of a tv unit throughout the last five years. The sofa was no longer in their product line and he got a replacement, he received new parts for the TV stand and chair. All these items had some wear but were not mistreated. Had that been the case he probably wouldn't have gotten his parts for free. Then again the issues he had with the furniture were quite minor (couch had a crooked leg and TV stand's door wouldn't close entirely).
Also you do need a receipt if you want to use your warranty. Apparently not always for returning items.
Edit 2: The friendly return policy is profitable for IKEA, have you ever gone to IKEA without buying at least 5 things?
I built it,
One piece at a time, and it didn't cost me a dime.
You'll know is me when I roll through your town...
It's a '63, '64, '65, '66, '67 automobile...
“Hey, I’m missing this here piece for desk model 60004736 in cherry black”
“Um, sir... that model is sold as a whole, not a set”
“Exactly, I’m missing the whole desk. The box just came with these instructions.”
Can confirm this actually works but way quicker than 6 months and with wayfair.com. wife and I ordered a nice TV console stand thing with sliding barn door style doors. It was on sale for like 170$.
As I was putting it together I noticed one of the pieces of a different color wood had a slight scratch in it. I thought it was a shelf and I wasn't sweating because I could just install it upside down and Noone would ever see the scratch. Well once my wife saw it she was like 'OH HELL NAW' and called them right away. The customer service person was like "no problem just tell me the piece number and I'll send a new one right away" well I was in the middle of putting the thing together so I had no idea what part it was. My wife tells them well call em back when we figure it out. Turns out the piece that had the scratch, was a protective board that was meant to take the bumps and scratches for this very purpose. We didn't call back.
Couple days later, wife gets an email from wayfair saying our order was shipped. Couple days after that fed ex guy is out front. They sent us a whole new full TV console thing. We called and was like we don't need this and the guy said it would cost too much to send back and this happens way more than you'd think and if we couldn't use it that if we could please donate it to someone who would need it. It was awesome 5/7 would buy from them again.
Sorry I'm on mobile.
Tldr: ordered furnature. Thought it was broke when we got it. Wayfair sent a whole other one for free when original wasn't broke afterall.
So in the military you can order replacement parts for the vehicles you work with and I know of a guy that almost damn near built a Land Rover part by part ordering the bits through the system and taking them home.
I do the same with Legos. 30 more years and I'll have half a millennium falcon.
