Review: Perfect replacement for original - Perfect replacement hardware for original
Review: Old POÄNG owners, this is the bolt you're looking for... - We had a bolt shear off on one of our older version IKEA Poang chairs (circa 2010-ish). Apparently, from scouring the internet, they've since redesigned the chair and no longer have these bolts as replacement parts. Further searching came up with this as the size of the bolt needed! The bolt in question was the top bolt in the picture, it attaches the seat bottom to the frame. As you can see, it's not an exact match -- because it's a slightly smaller diameter head -- but it works perfectly! Best part is, we don't need to replace our chair, sending it to a landfill -- and have spares in case the other bolts suffer the same fate.

### ⭐⭐⭐⭐ Held up over a year now.
*by F***E on January 22, 2026*

Bought these to replace the ones needed for a toddler bed. Needed 14 so had to leave two holes empty. Ha! And even then, the bed has held up super sturdy. Removed a star due to the paint easily scrubbing off with the included wrench. Easy to install and great price.
