Based on my observations, these casters ARE a perfect fit for my hardwood furniture! They move with ease and precision even under the heaviest load... The installation process was easy and straightforward. Plus, these casters are durable and long-lasting. The only downside I can think of is that they might not be suitable for delicate flooring as they could leave markings on softer materials. Overall, I highly recommend these casters for anyone in need of industrial and scientific material handling products..
