Look beautiful, have held up well. I put a sheepskin throw over them for texture. The plastic is not super smooth (not like fiberglass). The construction is good, not excellent. A little tiny bit wobbly on one but overall for the price they can't be beat!
These chairs are beautiful. Look much more expensive than they are. I've noticed some issues with 'static electricity' - could just be my office environment - but often find hair and other lint 'stuck' on them. Have also needed to re-tighten the hex bolts on occasion. So keep the small tool that comes with them!
These beauts are a great and affordable way to get that Eames look for less. Keep the alan wrench around to tighten the base bolts occasionally as the chairs settle into themselves. But so far we've had a dozen people sit in these - including two HUGE men (one 6'7" and the other 350lbs!) - so far so good.
