These are sturdy but not too heavy and we’re easy to put together. They come with four screws and you line up the feet where you want them and then screw them in. It took me 10 minutes to do two of these. They fit perfectly with our Wayfair chairs that are a different brand. It’s so nice to be able to put your feet up a little bit. These are made of recycled material that’s waterproof so they will last forever￼
