This is a decent buy for a guest bed, however, the machining was very chintzy.  Mine didn't come with a manual, but luckily Wayfair keeps assembly manuals for most products on your order page.

Assembly would have been easy, however, due to the poor machining, you had do really force some of the bolts in; I ended up having to set the torque up pretty high on my drill to get a few of them in, because the threads hadn't been drilled properly.

I wouldn't recommend this for anyone who plans to use it on a regular basis, but it works well as a guest bed.

On the plus side, even with build issues, it was still only a 30 minute job to put together.  It also looks very nice.
