These are solid built concrete skates/knee boards. They seem to be good quality and easy to clean up. It was a quick assembly. Some adjustment needed for the feet depending on your size. There are more comfortable designs in the knee area but these are sufficient with the padding attached. These will help you reach difficult areas on a concrete slab allowing you to keep a smooth surface. Make sure you wait until the concrete is at the right consistency then slip on your knee boards to access those hard to reach spots without sinking into the wet concrete. Priced at $100, these are pretty average as far as the value goes. They will definitely last a long time but make sure to keep them cleaned up for a life time of use.

As a contractor with over a decade of experience in concrete flatwork, I’ve gone through my fair share of knee pads, foam supports, and makeshift solutions for protecting my joints during troweling, screeding, and finishing jobs. That's why I was eager to try the Concrete Knee Boards 30x8 Inch – Heavy Duty Stainless Steel Sliding Support,

These edge protectors are impressively lightweight and easy to handle. If you want them to stay put, I highly recommend using Gorilla Glue and apply generously and wipe away any excess. Once secured, they perform exceptionally well. I customized mine by adding foam pads and removing the straps, but you can keep the straps and kneepads if that’s your preference. Honestly, most pros I know don’t bother with them. Compared to fiberglass boards, these metal boards do pull slightly under the knees, not a major issue, but worth noting. Personally, I prefer these because of the flared ends, which help prevent concrete from caking up along the edges (a common problem with flat fiberglass boards). One caution: these boards slide like butter on ice. Be careful when stepping on, especially if you’re not expecting it as it can be a little dangerous. Bottom line: Great performance, lightweight design, and smart edge protection. Just secure them properly and watch your footing.

I got these concrete knee boards recently, and they've been a lifesaver for my projects. The adjustable toe brackets are great for different leg lengths, making it super comfy and easy on my back. The sliding platform is smooth and fast, gliding over wet concrete without any damage. The comfy pads and straps are a plus for long work days, especially on big slabs. They work awesome, but maybe a lighter design would make them easier to move around. Still, I'd totally recommend them!

Working as a prior cement mason, these will come in handy as we are almost done with our Airbnb rehab. Our next project is a patio and this will be used for sure as we pave a patio in our large yard. The padding on these boards were really comfortable as my prior boards were stiff from the inappropriate padding, where these have a supportive padding like memory foam. I have huge feet in size 14, and these fit great with my concrete boots on. I could get in and out of these easily. These are made of a durable metal and feel heavier, stronger and appear more intricately made than the knee boards I had before. I'm excited to use these and will post photos of our concrete rehab once completed, in about another month.
