Instructions were challenging, yet I put it together without real problems.
Will not be using the leg rest, as it is held in place by plastic mounts I feel will not hold up to a 250lb man. Haven't proven this, but a leg rest was not a major concern for me anyway. I was thinking "Metal base" meant metal legs, but it does not. The "metal base" is under the seat. I feel I got my money's worth with this chair, but I do not feel it is appropriately rated at 330 lbs. It's a standard reclining desk chair with a leg rest tacked on with plastic mounts, and a couple cushions thrown in.  My last chair was basically the same, functionally, and cost $50 less. The leg broke on that one when I leaned to stretch, dumping me on the floor. This one has legs that look almost identical. I will NOT be reclining in it.
