If you've got a worn-out rocking chair or recliner that's seen better days, this BambooMN swivel rocker plate is exactly what you need to bring it back to life! Measuring 8.25 x 9.375 x 3 inches, this heavy-duty mechanism features three serious springs that provide that smooth rocking motion we all love. The mounting holes are rectangular shaped (about 7x23mm) with 5.5x6.25 inches between them, making installation straightforward if you're handy with basic tools. What's really cool is the 360-degree swivel function - you can rock and spin at the same time, which is perfect for those lazy Sunday afternoons. The construction is solid - this isn't some flimsy replacement part that'll break in six months. It's actually made right here in the USA, which explains the quality craftsmanship. Installation is pretty straightforward - there are mounting holes on both the top and bottom, so you can adapt it to different furniture designs. Whether you're restoring a family heirloom, building a new rocker from scratch, or just fixing that favorite chair that's been sitting in your garage, this mechanism delivers reliable performance. I used one to fix my grandfather's old rocking chair, and now it works better than it did when it was new! The rocking motion is smooth and quiet, and the swivel action is buttery smooth. It's amazing how such a simple replacement part can completely transform a piece of furniture.
