These are a good option for either doing a much thicker flooring or putting on top of the floor for a deadlift platform. If using for a platform it is a solid rubber and bounces less than expected. Biggest issue is that they are 3.2'x3.2" so if you are deadlifting more than 6 plates per side, they can start to not be on the platform.
This is a very solid, well-built half rack. 3x3 and 5/8" holes make it universal for so many different attachment options. Price is lower compared to the other bigger brands versions of this style of half rack
If you are looking for a Flat Bench for powerlifting this bench is great. It is 17" high and has a very grippy pad, single post in the front makes for nothing getting in the way of your feet when setting up.
