This is a fantastic box spring! I have put together other metal box springs before and this one was quite easy to build. I love that they included spare nuts and bolts!  There is no squeaking at all.  This is a great buy for the price and will last much longer than a wooden box spring. The cover is great quality as well. It was so easy to put on and is nice and thick. It is also easy to be removed in case it needs to be washed.
