This is pretty comfortable, and decently built. Legs are solid and the rocking motion is smooth. The faux Sherpa material is a little thin (you can see through it in some tighter spots), but this is a really good chair for the money.
As others have noted on similar (the same) chairs on Wayfair, this thing is excruciating to put together if the factory screw holes aren't perfectly aligned. If you have any muscle weakness or inability to get help with assembly, I'd recommend not buying this chair. My pregnant wife had no hope of doing this on her own. Thankfully, I had some extra long bolts lying around that I could use to hold one end in place while I screwed in the other side. Even with that, I nearly stripped the screws holding the back in place (using an allen wrench).

Now that it's together though, I have almost no complaints.
