Love the look of the chairs- easy to put together. Just needed a 2nd pair of hands to get the back piece in place to put the screws in.  The chair is rated for 300 lbs.  I weigh 125lbs  and when sitting in it, it gives a bit.  I was a little worried it might not be strong enough for my husband but he sat in and said it was comfortable and didn't notice any give ( he weighs 220lbs).  I of course then googled poly wood and it does give more than traditional wood.
