Major Squeaking caused by bad welding! Only fixed temp with WD-40 or re-welding the stubs: CORRECTLY. EDIT: AH-HAH! I found the issue with this bed frame! With many hours of troubleshooting I see the welding job is shoddy at best.... No issues with the screws, no issues with the joint plug-ins. It's the weld! It's in the weld... If you look at the Non-movable metal stubs that are welded into the frame, were you plug the joints into, you can see: That the weld is not welded fully, It's not welded on all sides. you can clearly see that the only weld is done on the inside of the stub. not the outside. this is causes SPACE IN BETWEEN THE METAL. (Temp fix WD-40) WHY? IDK! It's also not HEALTHY for LONGEVITY! I can already see the weld starting to crack after a months use and sooner or later it will snap.

This is a great frame! I LOVE it! but what broke it for me was the noise being caused by the shoddy welding job not being anywhere close to good quality! 
DO. NOT. GET. THIS. PRODUCT!
