Perfecto
Se rompió una de las puntas del pie de la silla del escritorio y no encontraba ningún repuesto. Y comprar una silla nueva no me parecía buena idea. Afortunadamente me encontré con este pie de metal universal y me salvó de un gasto innecesario!

Brilliant! Fixed an older chair.
I have a £125 "gamer chair" I've had for just over a year now, and one of the wheels popped off.. Because even though the base seemd quality it was plastic and was "honeycomb" around where the wheels clip in... Its this what broke, and this has been the offender for every chair.The missus suggested buying a new chair for £100+ but that seemed a total waste, and then I spotted this... Solid metal? £26? Seemed too good to be true?So it arrived, the alan key supplied is pretty poor quality but one end will work, so it's all assembled, I slap on the old wheels that came with the chair and boom!Winner winner chicken dinner, the seats as good as new! It is much higher than the old one, but everything seems better, sounds quiter on the floor boards, doesn't seem to creak as much, just feels really good and solid.I play a lot of online games from FPS to MMOROGs and pretty much everyone I know has had these issues, even with "£200+" chairs, now I'm glad I've found something to recommend... And I'm even more happy the "throw away society" didn't win this round with what's a perfectly fine chair (and perfect with this item on it).
