So far so good with this product! I was able to buy a metal bed frame and drill holes through that to mount it to these hydrolic arms. Very simple modification and these arms come with plenty of holes predrilled into the metal for east attachment to virtually and existing bed frame. While I haven_ actually completely built the bed frame and seen these things actually do what I bought them to do, I am pleased with the entire product experience so far.Also, great customer service from the company.
